If you’ve found that your diarrhea appears before your period, you’re not alone. Many people experience severe diarrhea with PMS. Your menstrual cycle and digestive system are closely linked.
Why do you get diarrhea before your period?
Levels of progesterone and estrogen change during your menstrual cycle. There are receptor cells for these hormones in your gastrointestinal tract. This suggests that the gastrointestinal tract is designed to sense and react to these hormonal changes.
Apart from hormones, another cause for diarrhea before your period is the increased amount of prostaglandins. Prostaglandins can make the muscle that lines your bowels contract and push waste out quickly.

Most premenstrual symptoms begin one to two weeks before your period. They might last up to seven days after the start of menstruation.

One study has shown that 73 percent of women experience at least one of the primary gastrointestinal symptoms either before or during their period. Roughly 24 percent of women said they experience diarrhea before their period, while 28 percent experience diarrhea during their period.
