About Lactose Intolerance

Lactose intolerance is a common problem of the digestive system that is caused by lack of the enzyme lactase, which is used to break down lactose, a natural sugar found in the milk of mammals, including cows, goats, and sheep. Foods that contain lactose include:

  • dairy products such as cream, cheese and yoghurt
  • biscuits and chocolate
  • some breakfast cereals
Symptoms of Lactose Intolerance

Lactose intolerance occurs when the body cannot break down and absorb lactose. It is usually caused by a lack of the enzyme lactase, which is produced by the small intestine. If there is not enough lactase in the small intestine, the lactose cannot be digested and it passes intact into the lower intestine, where it is fermented by bacteria and gives rise to abdominal symptoms such as:

  • a bloated stomach
  • flatulence (wind)
  • frequent diarrhoea
  • stomach pains and rumbling
  • nausea
  • stomach cramps

The symptoms of lactose intolerance can be very similar to those of other conditions, such as irritable bowel syndrome (IBS) or milk protein intolerance. IBS is a chronic (long-term) disorder that affects the digestive system. Milk protein intolerance is an adverse reaction to the protein in milk from cows, but it does not involve the immune system (milk allergy). Due to the similarities of these conditions they can easily be confused and so testing for Lactose Intolerance is particularly advantageous in ruling the condition in or out and enabling you to make appropriate changes to your diet.

Types of Lactose Intolerance

There are three different types of lactose intolerance. By far the most common is Primary lactose intolerance, an inherited condition where the production of lactase in the body usually starts to fall from the age of 3 years onwards. The symptoms of lactose intolerance develop over time and will vary from one individual to the next. Primary lactose intolerance is very common and found in approximately 5% of adults in the UK. In some ethnic populations its is even more common, particularly those where milk is not traditionally included in their diet. These include people of hispanic, south Indian, american indian and black or Ashkenazi Jewish origin, where lactose intolerance can occur in up to 50-80% of adults.

The other types of Lactose Intolerance are uncommon. Secondary lactose intolerance can occur as a side effect of other intestinal diseases, such as coeliac disease and is often temporary. Congenital lactase deficiency is a very rare genetic disorder present at birth. Our Lactose Intolerance kit confirms if you have the inherited Primary Lactose Intolerance from your DNA and cannot be used to identify the secondary or congenital forms.

Living with Lactose Intolerance

Lactose intolerance cannot be prevented or cured as it is a genetic trait that you inherit. However if have taken a test such as our Lactose Intolerance DNA test and you know for certain that you are lactose intolerant it can normally be controlled by making appropriate changes to your diet. By only eating or drinking dairy products that are within your body’s tolerance levels, or by choosing products with low levels of lactose, the symptoms can be controlled. Lactose intolerance can range from mild to severe, depending on how much lactose a person has in their diet and how well their body can digest it. The amount of lactose that it takes to start your symptoms will vary from person to person.  In more severe cases supplementary lactase enzyme can also be ingested with the food to make the lactose more digestible, on the advice of your dietician or doctor
