Why Do I Have Diarrhea Every Time I Eat?

Diarrhea after eating often indicates food intolerance, irritable bowel syndrome, or inflammatory bowel disease. Common triggers include lactose, gluten, high-fat foods, or artificial sweeteners. IBS affects 10-15% of adults and frequently causes post-meal digestive upset. Bacterial overgrowth, celiac disease, or gallbladder dysfunction can also trigger rapid bowel movements within 30 minutes to 2 hours after meals. Keep a food diary tracking symptoms, timing, and specific foods consumed. If diarrhea persists for more than a week or includes blood, fever, or severe dehydration, seek medical evaluation for proper diagnosis and treatment.
