Diarrhea during period is a common yet often overlooked issue that many women face, stemming from hormonal fluctuations in the menstrual cycle. Particularly, prostaglandins, which trigger uterine contractions, can also affect the gastrointestinal tract, leading to increased bowel movements and diarrhea. 

Research highlights the prevalence of gastrointestinal symptoms around menstruation. According to the BMC Women's Health, in a survey involving 156 women, a staggering 73% reported experiencing gastrointestinal symptoms before or during their period. Notably, 58% experienced abdominal pain before their period, and 55% during menstruation, while 24% reported having diarrhea before their period, with 28% experiencing it during. This data underscores the commonality of such symptoms among women during their menstrual cycle.

While it can be uncomfortable, understanding its causes, identifying risk factors, and adopting effective treatment and prevention strategies can greatly alleviate symptoms. This comprehensive approach ensures that period-related diarrhea does not significantly impact one’s daily life and well-being.

Diarrhea During Period

Causes of Diarrhea During Period

Many women notice a pattern of digestive issues, including diarrhea, coinciding with their menstrual cycle. But why does this happen? The primary culprit is the natural hormonal fluctuations that occur during a woman's menstrual cycle. Specifically, the levels of progesterone and estrogen significantly vary, impacting not just the reproductive system but also the gastrointestinal tract. These hormonal changes can lead to increased bowel movements and sometimes, diarrhea.

A significant player in this process is prostaglandins, chemicals released during menstruation that cause the uterus to contract to shed its lining. However, prostaglandins can also affect other muscles in the body, including those in the digestive tract, leading to more frequent bowel movements or diarrhea. This is a key factor in understanding why period diarrhea occurs.

Risk Factors for Diarrhea During Menstrual Periods

While most women may experience some form of gastrointestinal discomfort during their period, certain factors can increase the likelihood or severity of symptoms like diarrhea. Understanding these risk factors is essential for managing and mitigating the impact of period-related diarrhea on one's life.

Underlying Gastrointestinal Conditions

Women with pre-existing conditions such as Irritable Bowel Syndrome (IBS) or inflammatory bowel disease may find their symptoms exacerbated during their period. The hormonal fluctuations can trigger more severe reactions in their already sensitive digestive systems.

Diet and Lifestyle

Dietary habits can influence the severity of period diarrhea. Consumption of certain foods and beverages, such as caffeine, spicy foods, and high-fat foods, can aggravate the digestive system, especially during menstruation when it may be more sensitive.


There's a well-established link between stress levels and gastrointestinal symptoms. High stress can exacerbate symptoms of diarrhea and vomiting during periods, making it essential to manage stress effectively.

Hormonal Contraceptives

For some women, the use of hormonal contraceptives can impact the severity and frequency of menstrual symptoms, including gastrointestinal issues. The changes in hormone levels due to contraceptives can either alleviate or exacerbate these symptoms.


Recognizing these risk factors is crucial for individuals seeking ways to manage period diarrhea. Simple changes in diet, lifestyle, and stress management techniques can make a significant difference in how one experiences their menstrual cycle. Additionally, for those with underlying conditions, consulting with a healthcare provider for tailored advice is advisable.

Complications of Period-Related Diarrhea

Experiencing diarrhea during menstruation, while common, can sometimes lead to complications if symptoms are severe or overlooked. 

The primary concern with ongoing diarrhea is dehydration. This condition occurs because diarrhea leads to an increased loss of water and electrolytes (such as sodium and potassium) from the body. Dehydration can manifest through several symptoms, including but not limited to, feelings of dizziness, a significant decrease in urine output, dry skin, and an intense sensation of thirst. If dehydration becomes severe, it may require medical intervention to prevent further health issues.

Another significant complication associated with persistent diarrhea is nutrient malabsorption. When the digestive system is in turmoil, the efficiency with which it absorbs nutrients from the food you consume can decrease. This can lead to deficiencies in vital nutrients, vitamins, and minerals, affecting overall health and energy levels. Symptoms of nutrient deficiencies can vary widely, from fatigue and weakness to more severe health issues over time. Ensuring a well-balanced diet and possibly supplementing with vitamins, under a healthcare provider's guidance, can help counteract these risks.

Treatment for Diarrhea During Period

Managing symptoms of diarrhea and vomiting during menstruation involves several strategies aimed at reducing discomfort and preventing complications:

Dietary Adjustments

Modifying your diet can significantly impact your digestive health during your period. Incorporating foods that are gentle on the stomach and high in fiber can help firm up stools and reduce diarrhea. Bland foods, such as toast, rice, bananas, and applesauce, are often recommended for easing digestive discomfort. It's also beneficial to avoid known irritants like caffeine, spicy foods, dairy products, and high-fat foods during this sensitive time.


Given the risk of dehydration with diarrhea, increasing fluid intake is crucial. Water is always a good choice, but herbal teas and electrolyte-replenishing drinks can also be beneficial. These beverages can help replace lost fluids and minerals, aiding in the recovery of the digestive system.

Stress Management

Stress can exacerbate gastrointestinal symptoms, making effective stress management techniques a vital part of treatment. Practices such as yoga, meditation, deep-breathing exercises, or engaging in a favorite hobby can reduce stress levels and, by extension, the severity of period-related diarrhea.

Symptom Management

For those seeking immediate relief from diarrhea, over-the-counter medications can offer temporary respite. However, it's important to approach these remedies with caution and consult a healthcare provider if symptoms persist or worsen. Additionally, using the Symptom Checker can provide insights into whether your symptoms might be indicative of a more serious condition, guiding you on when professional medical advice is warranted.

Prevention of Diarrhea During Menstrual Periods

Preventing or reducing the severity of diarrhea during menstruation largely hinges on lifestyle and dietary choices. Implementing the following practices can offer relief:

  • Dietary Modifications: A diet rich in fruits, vegetables, whole grains, and lean proteins can support digestive health and reduce the incidence of diarrhea. Avoiding or limiting foods known to irritate the digestive system, especially during your period, can also be beneficial.
  • Regular Exercise: Engaging in regular physical activity has numerous health benefits, including improved digestive function and reduced stress. Even moderate exercise, such as walking or cycling, can help.
  • Adequate Hydration: Maintaining good hydration is essential for overall health and can prevent the constipation that sometimes alternates with diarrhea during menstrual periods. Aim to drink at least 8 glasses of water a day, more if you are experiencing diarrhea.
  • Stress Reduction: Since stress is a known trigger for gastrointestinal issues, finding effective ways to manage stress can mitigate symptoms of diarrhea during your period. Whether through meditation, relaxation techniques, or spending time on activities you enjoy, lowering stress is beneficial for your digestive and menstrual health.
  • Monitor Your Health: Keeping a symptom diary can help you identify patterns in your menstrual cycle and digestive health, allowing for better management of symptoms. This awareness enables you to take proactive steps in adjusting your diet and lifestyle as needed.


By taking a comprehensive approach to understanding, treating, and preventing diarrhea during your period, you can minimize its impact on your daily life. Remember, if diarrhea is severe, persistent, or accompanied by other worrying symptoms, seeking the advice of a healthcare professional is crucial to ensure proper care and treatment.
