dear asking for a friend,
i have a bit of an awkward question. i am in my thirties, and i have always had normal periods. but one thing that has always bothered me is the effect it has on my stomach — i often have diarrhea, cramping and gas along with my period. is this a thing?

dear number two,
in addition to a host of other
symptoms, including mood changes, bloating, cramping and food cravings, many women report gastrointestinal issues that show up like clockwork each month.
according to dr. aalia sachedina, clinical assistant professor in the department of obstetrics & gynecology at the
university of british columbia, fluctuating hormones are largely to blame.
“perimenstrual gastrointestinal (gi) symptoms are common, experienced by up to 70 per cent of women,” she says. “these can include abdominal pain, boating, nausea, vomiting, diarrhea and constipation. these symptoms can be caused by changes in hormone levels and release of inflammatory substances that occur during periods.”
sachedina adds that there are also some studies that suggest that mood changes — which are also common during and before menses — can have an effect on gi symptoms, including bowel habits.
