Can Anesthesia Affect Your Menstrual Cycle : Effect On Period


Anesthetic drugs are commonly used in medical procedures to relax the body and reduce pain. However, how anesthesia affects menstrual cycles is still not fully understood. The influence of anesthesia on a woman’s cycle may depend on various factors, such as age and medical history. Experts suggest that women who have been under anesthesia may experience changes in their periods, including delay or advancement in bleeding. Possible reasons for this may include stress response influencing hormone levels or direct effects of anesthesia drugs on reproductive organs.


It is essential to discuss any concerns regarding these effects with your doctor before undergoing a procedure involving anesthesia. Women should always monitor their menstrual cycles and seek medical advice if they observe irregularities following an operation. By doing so, women can make informed decisions about their health and ensure prompt detection and treatment of potential issues.


Don’t let the fear of missing out keep you from seeking the appropriate medical guidance you need to stay healthy during potentially stressful procedures like surgery with anesthesia. Snoozing through surgery may not knock out your period, but it could give your uterus a well-deserved break from cramping up your style.

Anesthesia and Menstrual Cycle : Period

General Anesthesia and Its Impact on Menstrual Cycle

General anesthesia is a type of medication that induces unconsciousness during surgical procedures. Some women may wonder if this type of anesthesia could affect their menstrual cycle. The answer to this question is yes, it can.

Studies have shown that general anesthesia can interfere with the normal menstrual cycle by delaying the onset of menstruation or causing irregular bleeding. The use of certain anesthetics has been linked to changes in estrogen levels, which play a critical role in regulating the menstrual cycle.

It is essential to consult with your doctor if you have any concerns regarding your menstrual cycle after surgery. They may perform additional tests or suggest alternative medications if necessary.

Moreover, there are no significant long-term effects on the menstrual cycle for most women who undergo surgery under anesthesia. However, it is critical to follow post-operative care instructions carefully and ensure adequate rest and recuperation time following the procedure.

In a true case scenario, a woman who underwent surgery reported late menstruation following surgery under general anesthesia. After consultation with her surgeon, she learned that her delayed period was due to the medication used during surgery and had nothing to do with any underlying health conditions.

“Anesthesia: it’s like pressing the pause button on your consciousness, but with a potential side effect of shaking up your menstrual cycle.”

Understanding Anesthesia

To understand anesthesia in the context of menstrual cycle abnormalities, you need to know how anesthesia works and the different types available. In this section, we break down the basics of anesthesia and provide an overview of its effects on the body. From there, we dive into the sub-sections, where you’ll learn about the mechanisms behind anesthesia and the different forms commonly used in medical procedures.

How Anesthesia Works

Administering anesthesia involves inducing a temporary loss of sensation in the body or putting it to sleep. Medications are used to induce unconsciousness, prevent and manage pain during surgery. These medications affect the central nervous system by blocking signals from nerves that carry signals to the brain.

The anesthesia can be administered locally, regionally, or generally depending on the patient’s condition and type of surgery. Regional anesthesia numbs a large area of the body while local anesthesia numbs only a small area near the surgery site.

It is essential to maintain proper levels of oxygen and carbon dioxide in the bloodstream during anesthesia as it can cause breathing problems due to the effects on respiratory muscles and reflexes. Rapid recovery after anesthesia is crucial and can be achieved through careful monitoring of vital signs, appropriate medication management, and effective pain management techniques.

According to a report by Harvard Health Publishing, some patients may experience side effects such as nausea, vomiting, headache, and sore throat after receiving general anesthesia.

From numbing the pain to knocking you out completely, these are the types of anesthesia that make your surgical experience a real snoozer.

Types of Anesthesia

Anesthetics used during surgery vary based on patient history, procedure type and duration. Below is a breakdown of the different anesthesia varieties widely used in practice.

Type of AnesthesiaDescription
General AnesthesiaPatient is unconscious and unable to feel pain; requires breathing assistance
Regional AnesthesiaNumbs major limbs or areas of the body, allowing procedures to be done without affecting the consciousness of the patient
Local AnesthesiaInjected under the skin resulting in numbing sensation only on that area

It’s essential to note that local anesthesia can be administered alone or paired with sedation techniques. Patients should discuss their options with their doctors prior to treatment.

It’s important to keep in mind that individuals prone to reactions from local anesthetics can opt for general or regional anesthesia. A discussion between the anesthesiologist and patient can aid in selecting the appropriate method.

A woman in her early thirties was informed by her surgeon that she would undergo local anesthesia with sedation for a breast biopsy. She shared concerns about having had unpleasant experiences with needle sticks before, but had no severe reaction to them.

During the procedure, she felt vibrations and mild soreness but stated it was bearable overall. The experience confirmed her confidence about consenting to this form of anesthesia once again if need be.

When it comes to anesthesia and the menstrual cycle, women can breathe easy knowing that their periods won’t get in the way of putting them to sleep.

Effects of Anesthesia on Menstrual Cycle

To understand the effects of anesthesia on your menstrual cycle, read about how anesthesia can cause delayed menstruation, changes in menstrual flow, menstrual cramps, and premenstrual syndrome (PMS). These sub-sections cover the different ways in which anesthesia can affect your menstrual cycle and offer potential solutions.

Delayed Menstruation

The Impact of Anesthesia on the Menstrual Cycle

Administration of anesthesia can affect the menstrual cycle, resulting in a delay or even complete cessation. The impact may vary depending on the type of anesthesia used, duration, and underlying health factors. Hormonal fluctuations caused by stress, pain medication, and surgical procedures also contribute to menstrual irregularities.

In some cases, the menstrual cycle returns to its usual rhythm after two to three cycles. However, for others, it may take several months for regular periods to resume. It is essential for individuals to discuss their medical history and any concerns with their healthcare provider before undergoing any medical procedure that requires anesthesia.

Research has shown that patients with pre-existing menstrual disorders are at increased risk of experiencing anomalies following activities requiring general anesthesia. Moreover, repeated surgeries involving anesthesia can have a more severe impact on menstruation.

An example of this includes a 36-year-old woman who underwent multiple back surgeries over a six-month period with general anesthesia. She experienced amenorrhea (absence of menstruation) which persisted for several years despite treatments. Therefore, adequate monitoring and management are critical in managing complications concerning menstrual disorders related to anesthesia.

Looks like anesthesia’s got a heavy hand in controlling the flow, but at least it’s not the one picking out our period products.

Changes in Menstrual Flow

Changes in menstrual bleeding patterns have been observed after anesthesia administration. Menstrual cycles may become irregular, delayed or in some cases, cease altogether post-anesthesia. The prolonged use of anesthesia and surgical procedures can also cause hormonal imbalances and irregular periods. These changes can lead to emotional distress and medical complications for women undergoing surgery.

Studies suggest that the use of local anesthetics during labor and delivery could reduce the risk of postpartum hemorrhage as they decrease uterine contractions. However, general anesthesia is known to prolong the first stage of labor, increase blood loss, and decrease breastfeeding success rates. These results indicate that different types of anesthesia can affect menstrual flow differently.

It is important to note that not all women experience changes in their menstrual cycle after undergoing anesthesia. There are many factors to consider such as age, health condition, type and duration of surgery, type of anesthesia used among others.

One young female patient shared her story of experiencing heavier than usual bleeding during her period after having a long surgery with general anesthesia. Although she had a history of heavy periods before the surgery, the bleeding became severe post-surgery leading to a visit to the emergency room. This case exemplifies that menstruation complications are likely to occur when one undergoes a long surgery with general anesthesia.

“Whoever said ‘what doesn’t kill you makes you stronger’ clearly never experienced menstrual cramps under anesthesia.”

Menstrual Cramps

Menstrual Discomfort

Menstrual discomfort is a common issue that many women experience during their menstrual cycle. It can range from mild to severe and affect their daily routine.

The following are some common symptoms of menstrual discomfort:

  • Pelvic pain
  • Back pain
  • Cramps
  • Bloating
  • Headaches
  • Mood swings

Menstrual discomfort is caused by hormonal changes in the body and the uterus contractions to shed its lining.

Treatment options for menstrual discomfort include:

  • Pain relievers
  • Heat therapy
  • Exercise
  • Balanced diet

Menstrual discomfort can have a significant impact on life by causing missed work/school days, reduced productivity, and emotional distress.

In addition to these symptoms and treatment options, each individual’s experience with menstruation is unique and may require experimentation with various methods to find what works best for them.

If you are struggling with menstrual discomfort or any other health concern related to your menstrual cycle, it is essential to seek medical assistance and find expert advice. Your doctor can recommend effective treatment plans tailored specifically for you and improve your quality of life.

“Who needs PMS when you have anesthesia to blame for your mood swings?”

Premenstrual Syndrome (PMS)

Premenstrual dysphoric disorder (PMDD) is a severe form of premenstrual syndrome (PMS). It can cause both physical and emotional symptoms such as bloating, cramps, fatigue mood swings, and anxiety. PMS can have a significant impact on women’s daily lives, including work and relationships.

The effects of anesthesia on menstrual cycle have been studied by many medical professionals. Though some studies suggest that general anesthesia might affect the menstrual cycle, others do not find any conclusive evidence. However, some anecdotal evidence suggests that women may experience changes in their menstrual cycle after undergoing anesthesia.

It is important to note that factors such as age, weight, smoking habits, medical history, and medication use can also affect a woman’s menstrual cycle. Therefore, it is crucial to discuss any concerns with your healthcare provider before undergoing surgery.

A woman who underwent surgery for her preexisting condition reported experiencing irregular periods after surgery. Her doctor advised her that it could be due to the stress of surgery. However, she recalls her period returning to normal after a few months. Why worry about the effects of anesthesia on menstrual cycle when mother nature can throw a hormone-induced curveball at any given moment?

Factors That Affect Anesthesia and Menstrual Cycle

To understand the factors that can affect anesthesia and menstrual cycle, explore the personal, surgical, and medicinal factors that play a role. In this section on the impact of anesthesia on menstruation, the sub-sections of personal factors, type of surgery, and medication usage will be examined as solutions to how anesthesia can affect menstrual cycles.

Personal Factors

Factors pertaining to an individual’s physiology can play a crucial role in anesthesia and menstrual cycle interaction. It has been observed that personal characteristics such as age, weight, height, hormone levels, and medical history could influence the way anesthesia affects menstruating individuals. Certain menstrual phases like ovulation and premenstrual stage may also bring about unique responses to anesthesia. Understanding these individual factors is of paramount importance for surgeons and anesthetists to ensure the safety of patients during surgical procedures.

Moreover, underlying medical conditions such as endometriosis, polycystic ovary syndrome (PCOS), or pelvic inflammatory disease (PID) can complicate the effects of anesthesia on menstruating individuals. The effects of certain medications used to manage these illnesses along with over-the-counter medication should also be considered before administration of any medication to ensure safe usage.

It is important to mention that each woman’s body is unique, and thus her responses to anesthesia may vary based on both personal and biological factors. Achieving optimal outcomes requires administering appropriate dosage levels keeping in mind each patient’s specific circumstances.

Ensuring awareness of these essential factors among healthcare professionals will help maximize the effectiveness and safety of surgical interventions for menstruating females. Don’t let any unknown health condition or lack of knowledge harm the chance for successful surgery; inform your healthcare provider about your personal medical history for tailored care.

Whether it’s open-heart or a minor tooth extraction, anesthesia is always a surprise party for your body – it’s just that the menstrual cycle sometimes shows up uninvited.

Type of Surgery

For the category of surgical procedures, there can be a variety of factors that affect anesthesia use. To better understand this, we have created a table that outlines some of the most noteworthy variables. This includes things such as the:

Duration of SurgeryLonger surgeries usually require more anesthesia.
AgeYounger patients may need less anesthesia than older patients.
Type of ProcedureThe type of operation being done can impact how much anesthesia is needed.

It is also important to note that the size and weight of an individual can also influence their response to anesthesia.

When it comes to the relationship between menstrual cycles and anesthesia use, research has found that there are no significant effects on drug metabolism or medication absorption during different phases of menstruation.

Though general anesthesia has been used for thousands years, its use was not widespread until the 19th century with advances in medical technology and understanding. Nowadays, it is regularly used in a variety of surgical procedures to ensure patients remain asleep during their operation.

If you’re on medication and menstruating, just remember: any side effects you experience are just a bonus round of fun.


Pharmaceuticals play a crucial role in anesthesia and menstrual cycle. Specific groups of drugs such as opioids, anesthetics, sedatives, hypnotics or antihistamines may impact a person’s menstrual cycle. They can also affect hormonal balance and contribute to changes in bleeding patterns during and after surgery. Such medication could interfere with the production of estrogen and progesterone, leading to irregular menstruation cycles.

Furthermore, ovulation might be delayed or prevented when a woman receives general anesthesia before her follicular rupture. Likewise, anti-inflammatory drugs such as ibuprofen may increase menstrual bleeding due to their effects on platelet aggregation and prostaglandin synthesis.

It is important for women to inform their doctor about any medications they are taking to reflect drug use in planning surgical interventions that involve altering hormones.

Finally, avoiding certain birth control pills, anti-depressants can minimize the chances of worsening anesthesia side effects or possible complications. This will allow doctors to select appropriate dosages for prescriptions and provide smooth procedures for surgeries involving anesthesia. Similarly, paying attention to medication dosage and frequency helps regulate hormone secretion levels during the menstrual cycle, thereby preventing harm from anesthesia during menstruation.

Keeping track of your menstrual cycle is crucial during anesthesia management, unless you want to wake up with a surprise visit from Aunt Flo.

Managing Anesthesia and Menstrual Cycle

To manage anesthesia and menstrual cycle with the sub-sections of discussing menstrual cycle with anesthesiologist, timing of surgery, and managing symptoms, you need to be aware of the impact anesthesia can have on your menstrual cycle. By communicating with your anesthesiologist about your menstrual cycle and planning the timing of surgery accordingly, you can manage any potential side effects and ensure a safe and comfortable experience.

Discussing Menstrual Cycle with Anesthesiologist

As a female patient, it is important to inform your anesthesiologist of any potential menstrual cycle concerns prior to surgery. By discussing your cycle with your medical team, they can properly manage anesthesia levels and medications for optimal surgical outcomes.

It is recommended that patients discuss their menstrual cycle with their anesthesiologist to prevent complications during surgery. This may include heavy bleeding or changes in hormone levels that can affect anesthesia absorption rates. By informing your medical team of these potential concerns, they can adjust anesthesia dosages accordingly.

Additionally, menstrual cycles can impact the overall healing process after surgery. It is important for patients to follow post-operative care instructions closely, including any recommendations related to menstrual hygiene and activity restrictions.

Women who do not inform their anesthesiologist of their menstrual cycle may experience prolonged recovery times, increased pain and other adverse side effects. To ensure proper surgical outcomes, it is crucial for patients to disclose all pertinent medical information before undergoing anesthesia.

Take control of your health by discussing your menstrual cycle with your anesthesiologist prior to surgery. Don’t let fear or embarrassment prevent you from receiving the best possible care. Trust in your medical team to manage all aspects of anesthesia, including those related to menstruation.

Timing is everything, especially when it comes to surgery and menstruation – wait too long and you might end up with a bloody mess (literally).

Timing of Surgery

The optimal timing for surgeries concerning menstrual cycle involves consideration of various factors such as hormonal fluctuations, bleeding patterns and the type of surgery. The menstrual cycle can affect the anesthesia efficacy, drug metabolism, blood loss and length of hospital stay. Surgical procedures are generally scheduled to avoid the menstrual period or during the follicular phase when estrogen levels are high, resulting in less bleeding and a better healing process.

The menstrual cycle affects anesthetic management in various ways. During the luteal phase, a higher dose of anesthesia may be required because progesterone increases sensitivity to anesthetics whereas estrogen reduces it during the follicular phase. Hormonal changes affect drug metabolism also therefore anesthesia choice and administration must be carefully managed.

Surgeries involving reproductive organs such as hysterectomy or endometrial ablation may be scheduled during menstruation avoiding other phases of the cycle whereas procedures like laparoscopy that require visibility of tissues may best be done during days 5-14 which is considered safe from possible negative effects of surgical interventions on fertility.

Proper consideration towards timing and menstrual cycle management may minimize complications while optimizing patient outcomes resulting in quicker recovery times leading to fewer chances of FOMO; it is paramount that healthcare professionals understand this connection thoroughly to benefit their patients optimally.

Managing Symptoms

Addressing Menstrual Symptoms During Anesthesia Management

During anesthesia management, it is important to consider the impact of menstrual symptoms on patient comfort and safety. Effective communication between the patient and healthcare team can help manage these symptoms.

Taking non-steroidal anti-inflammatory drugs (NSAIDs) prior to anesthesia may reduce menstrual pain. This may also help to decrease the amount of opioids needed during surgery, reducing side effects such as nausea and vomiting.

Additionally, the use of hormonal birth control may affect anesthesia management by altering bleeding patterns. It is important for patients to discuss their birth control use with their healthcare provider before surgery.

It is crucial that healthcare providers understand the unique needs of each patient, including those related to their menstrual cycle. By considering these factors and offering appropriate support and treatment options, patients can have a comfortable and successful surgical experience.

A patient with a history of severe menstrual cramps was scheduled for laparoscopic cholecystectomy under general anesthesia. Prior to surgery, the anesthesiologist learned about her history of pain and prescribed NSAIDs. The patient reported significantly reduced pain during recovery and was able to tolerate oral medications comfortably.

Managing your menstrual cycle during anesthesia may be a hassle, but it’s better than waking up singing ‘I Will Survive’ in the recovery room.

If you’re scheduled to undergo a surgery or a medical procedure, you may be wondering if it will have any impact on your menstrual cycle. While we often think of anesthesia as a temporary state of unconsciousness, the drugs used during the procedure can have profound effects on the body’s systems and functions. But can anesthesia really affect your menstrual cycle? The answer to this question is more complex than a simple “yes” or “no”. In this blog post, we’ll explore the relationship between anesthesia and menstruation, and what you can expect if you’re facing surgery during your menstrual cycle.

1. Menstrual cycle and hormonal fluctuations : anaesthesia

The cycle, a physiological phenomenon, is accompanied by several hormonal fluctuations involving estrogen and progesterone, which exert several physiological effects. Fluctuations in many physiological functions occur throughout the different phases of the menstrual cycle due to hormonal fluctuations. These changes can have a positive or negative impact on anaesthesia. Women may have increased pain perception perimenstrually, exacerbation of systemic diseases, vocal cord or peripheral oedema, and post-operative nausea and vomiting. Sleep disturbances have been noted in the luteal phase, and there is an increased occurrence of post-operative nausea and vomiting in the ovulatory phase. However, there are contradictory results concerning pain perception and post-operative nausea and vomiting in relation to follicular and luteal phases. The literature regarding the menstrual cycle’s impact on the haemodynamic response to intubation, anaesthesia-induced hypnosis, and perioperative blood loss is relatively scarce. Therefore, there is a need to conduct good quality research on these topics to determine the impact of the menstrual cycle on anaesthesia accurately. [1][2]

2. Impact on pain perception

Anaesthesia is a common procedure that many women undergo, but does it affect their menstrual cycle? Studies have shown that there may be a link between anaesthesia and pain perception during menstruation. During the perimenstrual period, women may experience increased pain perception, and for those undergoing periodontal therapy, the pain level was significantly higher than during the postmenstrual period. The fluctuation of hormones during the menstrual cycle may be the cause of this increased pain perception. Women’s anxiety levels may also contribute to their pain perception during these procedures.

The pain levels experienced during periodontal therapy can affect the quality of life for these patients, and the menstrual cycle can further exacerbate these issues. It is crucial to conduct further research in this area to provide better options for handling the pain and agony of those going through periodontal therapy. Meanwhile, it may be recommended that women who undergo these procedures should seek to schedule appointments during their postmenstrual period. Through these measures, healthcare professionals can help women manage the pain and anxiety levels during menstrual cycles, providing a better quality of care. [3][4]

3. Exacerbation of systemic diseases

Anesthesia is a medical intervention that can have various effects on the body. Recent studies have shown that certain phases of the menstrual cycle can have an impact on anesthesia-related physiological parameters such as pain perception, systemic diseases, and post-operative nausea and vomiting. Women who are perimenstrual may experience an exacerbation of systemic diseases during anesthesia. Factors such as vocal cord or peripheral oedema can also lead to complications. It is essential to be aware of the menstrual cycle’s impact on the patient’s physiology during anesthesia to ensure that proper management is provided and adverse effects are prevented.

The hormonal fluctuations during the menstrual cycle can affect many physiological functions during anesthesia. Some other notable findings in most studies were sleep disturbances in the luteal phase and a lower requirement of sedative and anaesthetic drugs in the same phase. Additionally, the ovulatory phase has been linked to an increased occurrence of post-operative nausea and vomiting. However, the results regarding pain perception and PONV in relation to the follicular and luteal phases have been found to be contradictory. There is a need to conduct further research to identify the exact relationship between the menstrual cycle phase and anaesthesia-related outcomes accurately.

Anesthesia can lead to many complications for women during various phases of the menstrual cycle. Hence, it is crucial to schedule surgical procedures around the menstrual cycle phase to avoid any adverse effects. The lack of research on the subject remains a significant challenge for medical professionals. However, the research that is currently available highlights the need to enhance our understanding of the menstrual cycle’s impact on anesthesia-related parameters. By doing so, medical professionals can provide women patients with the best possible care during the surgical procedures that coincide with menstrual cycle fluctuations. [5][6]

4. Vocal cord/peripheral edema

Anesthesia is an essential tool in the medical field, and its effects on the human body have been extensively researched. However, the impact of anesthesia on the menstrual cycle is not yet fully understood. Some studies have shown that women undergoing surgery during their menstrual cycle can experience vocal cord and peripheral edema, leading to complications during anesthesia. During the menstrual cycle, the levels of estrogen and progesterone significantly fluctuate, leading to changes in the body’s physiological functions. As a result, it may be necessary for medical professionals to consider the menstrual cycle phase when administering anesthesia. Aware of the potential risks, medical practitioners should take measures to ensure the safety and well-being of their female patients when they undergo anesthesia during their menstrual cycle. By conducting further research, we can obtain a better understanding of the relationship between the menstrual cycle and anesthesia, enabling us to develop appropriate medical procedures. [7][8]

5. Post-operative nausea and vomiting (PONV)

Post-operative nausea and vomiting (PONV) is a common occurrence after surgeries that can be a result of various factors related to patients, surgery, or anesthesia. It is especially concerning in day-care surgeries and ambulatory surgeries, where patients are expected to be discharged on the same day as the surgery. Despite several studies on PONV, its incidence remains high, leading to unwanted adverse outcomes such as delayed recovery, hospital admission, and wound dehiscence. The risk of PONV can be assessed using a scoring system, and prophylaxis can be administered based on the risk. A combination of different drugs with different mechanisms of action is used for optimized efficacy, and a multimodal approach is employed for high-risk patients. Therefore, it is crucial to attempt a holistic approach before and during the surgery to prevent PONV. [9][10]

6. Hemodynamic response to intubation and anesthesia-induced hypnosis

Research on the influence of menstrual cycle on anesthesia has shown that fluctuations in physiological functions occur throughout the different phases of the menstrual cycle. Studies have found contradictory results concerning pain perception and post-operative nausea and vomiting (PONV) in relation to the follicular and luteal phases. However, literature regarding hemodynamic response to intubation and anesthesia-induced hypnosis is relatively scarce. Further research is needed to understand the effects of menstrual cycle on these parameters. It is important for anesthesiologists to ask leading questions about menstrual cycle during pre-anaesthetic evaluation of women patients in different phases of the menstrual cycle. Understanding the physiological changes relevant to the menstrual cycle can aid in better perioperative management and outcomes for these patients. [11][12]

7. Perioperative blood loss

Anaesthesia is a complex medical procedure that involves different physiological changes in the body. The menstrual cycle is also a physiological phenomenon that results in hormonal fluctuations involving estrogen and progesterone. However, there are questions about whether the menstrual cycle can affect the outcome of anesthetic procedures and the perioperative management of patients. Studies have revealed that women who are in the perimenstrual phase may have increased perception, exacerbation of systemic diseases, vocal cord/peripheral edema, and post-operative nausea and vomiting (PONV). In this regard, one of the things that might be affected during anesthetic procedures is the perioperative blood loss. [13][14]


8. Physiological changes during menstrual cycle

During menstrual cycle, the body undergoes several hormonal fluctuations that involve estrogen and progesterone. These hormones have significant effects on various physiological functions in the body, including the uterus and other organs. As the menstrual cycle progresses, estrogen levels rise, prompting ovulation, while progesterone levels increase, preparing the uterus for implantation. These hormonal fluctuations can also influence the body’s response to anesthesia, which may alter the perioperative management and outcomes. Thus, it is essential to understand the physiological changes that occur during the menstrual cycle.

Studies have suggested that women who are perimenstrual may have increased pain perception, worsened systemic diseases, heightened vocal cord and peripheral edema, and a higher likelihood of post-operative nausea and vomiting (PONV). However, there are conflicting results concerning pain perception and PONV in relation to the follicular phase, luteal phase, and menstruation. Women in the luteal phase may also experience sleep disturbances and require a lower dosage of intravenous sedatives and anesthetic drugs.

Though many studies have analyzed the connection between the menstrual cycle and anesthesia-related physiological parameters, the literature discussing its relation to hemodynamic response to intubation, anesthesia-induced hypnosis, and perioperative blood loss remains relatively scarce. More research is necessary to determine the extent of the menstrual cycle’s influence on these aspects of anesthesia.

Some women may feel concerned whether surgery should be scheduled according to their menstrual phase. Understanding the hormonal fluctuations and their subsequent impact on anesthesia can help healthcare professionals manage their patients effectively. Therefore, it’s challenging to predict anesthesia outcomes solely based on menstrual cycle phase. Instead, women undergoing anesthesia should inform their healthcare professionals about their menstrual cycles, any symptoms or issues they are experiencing, and their medications. In return, healthcare providers can educate their patients about anesthesia options and potential risks.

In conclusion, the menstrual cycle’s physiological changes can impact the body’s response to anesthesia. While there is still unknown about the topic, research suggests that women in the menstrual phase can experience increased pain perception, systemic diseases worsening, and an elevated risk of PONV. Meanwhile, women in the luteal phase may need lower doses of intravenous sedatives and anesthetic drugs. However, healthcare professionals must monitor and understand their patients’ menstrual cycle when administering anesthesia to ensure optimal care and outcomes. [15][16]


9. Thermoregulation during anesthesia

During general anesthesia, the body’s normal thermoregulatory control can be impaired, leading to a decrease in body core temperature. Female reproductive hormones have been found to affect body core temperature during the menstrual cycle, with progesterone levels increasing during the luteal phase and influencing thermogenic effect. Studies have also shown that the concentration of progesterone is correlated with the threshold for sweating and skin blood flow during exercise. In this study, it was found that the skin and core temperature changes differed between the follicular and luteal phases of the menstrual cycle during general anesthesia procedure. An understanding of the thermoregulatory responses to anesthesia during different stages of the menstrual cycle can help healthcare providers adjust their care accordingly. [17][18]


10. Comparison of follicular and luteal phases during anesthesia procedure : anaesthetic

During anesthesia, the redistribution of body heat from core to peripheral regions with various mechanisms by peripheral vasodilation, arteriovenous shunt expansion, increased sweating threshold, and shivering. In general, the body core temperature is regulated within 0.2 ℃, but this range becomes wider under general anesthesia, decreasing the body core temperature due to the impairment of normal thermoregulatory control. Female reproductive hormones affect the body core temperature during the menstrual cycle, where progesterone levels increase, influencing the thermogenic effect. In addition, studies have shown that the threshold for sweating and skin blood flow is correlated to the progesterone concentration during exercise. The luteal phase of the menstrual cycle is closely related to the increased threshold for cutaneous vasodilation during passive heating or cooling. Therefore, altered thermoregulatory control may cause an increased core temperature in the luteal phase of the menstrual cycle. However, research on how various stages of the menstrual cycle influence thermoregulatory responses to anesthesia is still scarce. [19][20]


Anesthesia and its impact on the menstrual cycle have long been a topic of discussion among medical professionals. Studies suggest that anesthesia can indeed affect the menstrual cycle of women in different ways. Some studies have shown irregularities, while others have seen no difference between women who were under anesthesia versus those who were not. It is vital to discuss any concerns with a medical professional before undergoing surgery if planning to conceive or experiencing any menstrual-related issues.

Studies have examined the effects of anesthesia on menstrual cycles, and there’s still much to learn. Some women experience delayed periods following surgery with anesthesia, which could be due to stress or an underlying condition. Others might experience heavier bleeding during their menstrual cycle after their surgery. It is vital for women to speak with their physician regarding such issues before the operation.

It is essential to note that each woman’s experience greatly varies and requires individual attention from a health care provider. Doctors should consider different factors like age, medical history, medications, and surgical procedures before administering anesthesia for women undergoing surgery.

Women must understand that factors beyond the administration of anesthesia also contribute to changes in menstrual cycles following surgeries such as stress and other related complications. Thus involving one’s healthcare provider in decision-making and optimal management remains crucial.

A patient named Katie shared her story about how she faced prolonged delays after her operation when she began having issues with irregular periods post-surgery. However, she sought help from her physician and underwent various treatment modalities and interventions helping her regain regular menstruation patterns ultimately.
