Why Does Diarrhea Occur During Menstruation?
Menstrual diarrhea may be triggered by a cold. Inadequate abdominal warmth during menstruation can easily lead to abdominal chills, potentially resulting in acute enteritis and subsequent diarrhea. Under a physician’s guidance, medications such as Changyanling (a traditional Chinese medicine for enteritis) or Xieliting (an anti-diarrheal) may be used for treatment. Additionally, proper abdominal protection is essential—for instance, applying a warm compress using a hot water bottle. Menstrual diarrhea compromises the body’s immune resistance and impairs absorption of vitamins and nutrients, potentially leading to vitamin deficiencies and malnutrition.

These conditions can impair the body’s ability to resist viral infections, increasing susceptibility to viral illnesses. Severe diarrhea may cause disturbances in water and electrolyte balance as well as acid-base equilibrium. Profound fluid loss due to severe diarrhea can result in dehydration, further disrupting water, electrolyte, and acid-base homeostasis.

Menstrual diarrhea may negatively affect fertility. The associated nutrient loss hinders optimal conditions for conception. Chronic malnutrition may also impair ovarian development and compromise oocyte quality. Women with dual deficiency of qi and blood are at higher risk of miscarriage compared to those with normal constitution. We hope this information proves helpful!
