There's no cure for lactose intolerance, but limiting your intake of food and drink containing lactose usually helps to control the symptoms. Depending on what dairy products you're able to eat, you may also require additional calcium and vitamin D supplements to keep your bones strong and healthy. In some cases, your GP may refer you to a dietitian for further advice. In addition to dietary changes, lactase substitutes may also be helpful. These are drops or tablets you can take with your meals or drinks to improve your digestion of lactose.
