Capsaicin burns a sensitive gut lining - milk calms it, antacids help the acid. Pain between meals, at night, or with black stools or weight loss: get checked for an ulcer.
What to do
Common questions
Why do I get stomach pain after eating spicy food?
Spicy food hurts because capsaicin - the heat molecule in chilies - binds pain receptors in the gut lining, the same ones it lights up in your mouth. In a healthy gut, that produces a burning discomfort that passes; in a gut already irritated by reflux, gastritis, or an ulcer, spicy food pours fuel on the fire. The NHS notes that rich, spicy, and fatty foods are classic indigestion and heartburn triggers. Contrary to old belief, chili does not cause ulcers - bacteria and NSAIDs do - but it advertises them loudly: if modest spice reliably brings burning pain, the lining may already have a problem worth checking. Managing: milk and yogurt neutralize capsaicin better than water - the casein protein pulls it off receptors; smaller portions and slower eating reduce the total insult; antacids handle the acid component; and easing off spice while symptoms settle gives the lining time to heal. Track whether the pain is spice-only or follows other triggers too - coffee, alcohol, NSAIDs - since a pattern of general sensitivity points at gastritis or an ulcer rather than chili intolerance. When to escalate: burning pain that persists between meals or wakes you at night - the ulcer pattern - pain with vomiting blood or black stools, pain with unexplained weight loss, or pain that keeps worsening. Those go to a provider, and the bleeding signs promptly. Pymander is a free AI doctor, 24/7 by text. Describe the burn and its timing, and it can help you read what is underneath.
