Lactose intolerance

This is an absence of the enzyme lactase and is common in people from Mediterranean origin and those from the Indian sub-continent and also occurs in other populations. The best diagnosis is a hydrogen breath test (see investigations, and can be diagnosed with a test at endoscopy when a small piece of the small intestine lining is place in a special bedside lactose testing advice, and manifests as before).
