Most women and people who menstruate complain about bloating during their menstrual cycle.

Constipation is highly noticeable in women before their period starts. The menstrual cycle affects the gastrointestinal tract in how it works to push out waste from the body. The main cause behind this is progesterone level. High level of progesterone causes some slackening of the muscles, leading to a reduction in gastrointestinal motility, and which in turn may lead to bloating and constipation in some women.
