Diarrhoea after every meal

Every meal can activate bowel movement, but persistent urgency may also reflect an intolerance, excess thyroid activity, inflammation, or altered gut sensitivity. Food Intolerance can affect particular ingredients, whereas Irritable Bowel Syndrome often involves a recurring relationship between stool change and abdominal discomfort. Coeliac Disease and Crohn's Disease can cause ongoing bowel symptoms and need clinician assessment. A recent infection, including Gastroenteritis, Food Poisoning, or Giardiasis, may leave the bowel sensitive for a while. Medicines, supplements, and sugar-free products are also worth reviewing.

Arrange a routine medical appointment rather than repeatedly guessing which foods to remove. Until then, drink regularly and use oral rehydration solution if fluid loss is significant. Eat smaller portions of simple foods and avoid obvious personal triggers, alcohol, and very fatty meals. Keep your usual diet as broad as you can tolerate so that a food diary remains useful. Note whether symptoms occur overnight, the stool appearance, pain, fever, travel, recent antibiotics, and any weight change.

Seek urgent help for severe dehydration, fainting, confusion, severe abdominal pain, repeated vomiting, or bloody or black stools. Ask for prompt medical advice if the pattern is continuing, you are losing weight, have fever, or are passing very little urine. A clinician can examine you and choose focused tests instead of relying on symptoms alone.

Could my medicines or supplements be contributing? Which tests fit this repeated pattern? Should I change my diet while waiting for assessment? What signs mean I should seek urgent care?
