Causes

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

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

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

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

Symptoms of lactose intolerance

Symptoms of lactose intolerance usually develop within a few hours of consuming food or drink that contains lactose.

They may include:

The severity of your symptoms and when they appear depends on the amount of lactose you have consumed.

Some people may still be able to drink a small glass of milk without triggering any symptoms, while others may not even be able to have milk in their tea or coffee.

Medical treatments

There's no cure for lactose intolerance, but cutting down on food and drink containing lactose usually helps to control the symptoms.

Lactose-free products include:

  • lactose-free cows' milk
  • soya milks, yoghurts and some cheeses
  • rice, oat, almond, hazelnut, coconut, quinoa and potato milks

Your GP may also recommend calcium and vitamin D supplements.

You may be advised to take lactase substitutes, which are drops or tablets you can take with your meals or drinks to improve your digestion of lactose.
