Many women experience digestive changes and issues during periods, one of them being diarrhea. It happens because of hormonal fluctuations in the body. Here are a few reasons why some women experience diarrhea during periods. Tap to know!

Hormonal Changes

When on periods, our body releases prostaglandins, a chemical that helps shed the uterine lining. However, excessive release of this chemical can lead to diarrhea.

IBS

Women with Irritable Bowel Syndrome (IBS) may experience worsened symptoms due to oestrogen and progesterone fluctuations during periods.

Water Retention

Before periods, the body retains water that can cause bloating. However, when the periods start, the body releases the water that can also cause diarrhea.

Low Progesterone

During periods, progesterone (hormone that supports menstruation) levels are low in the body, making the digestive system more active and leading to diarrhea.

IBD

Irritable Bowel Disease (IBD) can worsen during periods as it can increase inflammation in the digestive tract, worsening the diarrhea.

Cravings

While menstruating, women often crave sweets, coffee, junk food, and more that can irritate the stomach and cause loose stools or diarrhea.

According to PubMed, some women may experience diarrhea during periods due to IBS, IBD, low progesterone levels, and more. It is advisable to consult a gynaecologist for personalised suggestions.
