Lactose intolerance is not the same as a food allergy to milk. It is a common digestive problem which means the body cannot digest lactose, a type of natural sugar, found mainly in milk and dairy products.

The body digests lactose using a substance called lactase. This breaks down lactose into two sugars called glucose and galactose, which can be easily absorbed into the bloodstream. People with lactose intolerance do not produce enough lactase, so lactose remains in the digestive system where it’s fermented by bacteria. This leads to the production of various gases, which cause uncomfortable symptoms such as flatulence or wind, stomach cramps, pains and bloating.

Some people who have lactose intolerance cannot digest any milk products. Others can eat or drink small amounts of milk products or certain types of milk products without problems.

Lactose intolerance usually affects older children and adults because the level of lactase starts to decrease naturally as you get older. It is more common in people of Asian, African and South American descent.

A big challenge for people who are lactose intolerant is learning how to eat to avoid discomfort whilst still getting the right amount of calcium for strong and healthy bones.

If you think that you may be lactose intolerant, it could be well worth your while doing our Lactose Intolerance DNA Test to see whether or not you carry the gene mutation responsible.

If you suspect that the symptoms you are experiencing may be due to lactose intolerance, you have probably given some thought to getting a diagnosis.

Collecting samples for a Lactose Intolerance Test at home is more comfortable and less time-consuming than traditional methods such as a hydrogen breath test, lactose tolerance test or milk tolerance test.

The test analyses analyzes the Beta-D-Galactosidase gene and determines whether the enzyme responsible for lactose digestion is functioning.

A Lactose Intolerance DNA Test does not require you to give a blood sample. Our test is carried out using the mouth swabs that we provide for you in our home sample collection kit. Sample collection is quick and easy, providing that you carefully follow the instructions provided.

You can view sample collection instructions on our How to Collect DNA Samples page.

There is no cure for lactose intolerance. You should change your diet to minimise symptoms by avoiding or cutting down on milk products.

If you can’t eat any dairy foods then you may not get enough calcium in your diet. Non-dairy foods that contain calcium include green leafy vegetables, soya beans, tofu and sardines.

If you are concerned about your diet then you should talk to your GP who may refer you to a dietitian for help and support. Your GP may also recommend that you take calcium and vitamin D supplements.
