Why do i have diarrhea when going off my cycle and how can i ease it?

Diarrhea: Because of the hormonal fluctuations, many women do experience cramping and some diarrhea periodically during their cycles. Is this a normal occurrence for you? Generally, as long as you keep well hydrated, you will fare well. If it is more than 5 days after your menses ceased, on this occasion, you might be dealing with a viral gastroenteritis. Pepto bismal helps - but only for occasional use.
