What is lactose intolerance?
What are the symptoms of lactose intolerance?
Symptom: Abdominal bloating
How do you diagnose lactose intolerance?
- Hydrogen breath test: This test measures the level of hydrogen that's found on your breath. The higher the amount, the more likely that lactose has been fermented by bacteria in the bowel, rather than being converted by lactase.
- Elimination diet: This process involves eliminating foods and drinks containing lactose from your diet, then slowly beginning to reintroduce foods while keeping a diary of your symptoms. If symptoms reappear, then lactose intolerance is most likely the cause.
