Why do I get stomach pain after eating eggs?

Stomach pain after eggs splits into intolerance and allergy, and the distinction matters. Intolerance: the gut struggles with eggs - often the fat in the yolk or the sulfur compounds - producing cramping, bloating, gas, or loose stools an hour or two after eating, with symptoms that scale with the amount. Allergy: the immune system reacts to egg protein - MedlinePlus lists hives, swelling, vomiting, and breathing difficulty among food allergy symptoms - and reactions can escalate with repeated exposures. Egg allergy is common in children and usually outgrown, but adult-onset egg allergy exists, and adults who keep childhood allergy can react harder. Telling them apart at home: intolerance is dose-dependent and gut-only - a bite might be fine, three eggs are not. Allergy tends to react to small amounts, comes on faster - minutes to an hour - and brings non-gut signs: itching, hives, lip or tongue tingling. A food and symptom diary for two weeks usually makes the pattern obvious. The allergy red flags are anaphylaxis signs: trouble breathing, throat tightness, swelling of lips or tongue, faintness, or spreading hives - emergency, call an ambulance. For suspected intolerance: cook eggs thoroughly - some people tolerate well-cooked egg but react to runny - try egg-free stretches, and mention persistent reactions to your provider, who can arrange testing when allergy is in doubt.
