Lactose intolerance

Symptoms of lactose intolerance may include farting, stomach cramps or diarrhoea a few hours after having food or drink containing lactose.

Lactose intolerance is caused by your body not producing enough lactase, a substance that helps you digest lactose.

You can control the symptoms of lactose intolerance by avoiding food and drink containing lactose.

Lactose intolerance is where you cannot properly digest lactose, a type of sugar found in milk and dairy products.
