Stomach Pain and Diarrhea
Eating chili can cause intestinal distress in some people.
The symptoms may include abdominal pain, burning sensation in the gut, cramps, and painful diarrhea.
This is more common in people with irritable bowel syndrome. Chili can temporarily worsen symptoms in those who are not used to eating it regularly (29, 30, 31).
For this reason, people with irritable bowel syndrome may want to limit their consumption of chili and other spicy foods.
