Study Says 73% of Women Report Period GI Symptoms as Research Probes Hormonal Cause

Summary
A study cited in new reporting found 73% of healthy premenopausal women had at least one significant gastrointestinal symptom before or during menstruation, with abdominal pain and diarrhea most common.
Falling estrogen and progesterone levels appear to trigger prostaglandin production in the uterus, and researchers think those compounds may spill into the bloodstream and stimulate gut contractions that mirror menstrual cramps.
A second theory points to the vagus nerve, which can increase gut fluid release and muscle contractions; people with IBS, inflammatory bowel disease or endometriosis often report worse symptoms around their periods.
Treatment options remain limited: the only randomized probiotic trial improved indigestion but not diarrhea, while ibuprofen and naproxen may reduce prostaglandins yet can also irritate the gut and worsen some bowel diseases.
Judkins says practical steps for now are hydration, more fiber, less greasy food and possibly exercise, while the larger problem is a lack of menstrual-health research despite symptoms affecting a large share of women.
