Lactose intolerance is a problem that makes it hard to digest lactose. Lactose is a sugar that is found in milk and milk products. Some children don't make enough of an enzyme called lactase. This is used to digest lactose. When this happens, it can cause gas, belly pain, diarrhea, and bloating. This is not the same as a food allergy to milk.
Lactose intolerance affects different children in different ways. Some children cannot digest any milk products. Other children can eat or drink small amounts of milk products or certain types of milk products without problems. You can help your child learn how to avoid discomfort and still get enough calcium to build and maintain healthy bones.
Lactose intolerance is a problem that makes it hard to digest lactose. Lactose is a sugar found in dairy products. This condition causes gas, belly pain, bloating, and diarrhea. You can reduce the discomfort by avoiding milk products, using reduced-lactose products, or taking a supplement that helps you digest lactose.
Lactose intolerance isn't the same as a milk allergy.
Symptoms of lactose intolerance can be mild to severe. Your symptoms may depend on how much lactase your body makes. Symptoms usually start 30 minutes to 2 hours after you eat or drink milk products.
Symptoms may include:
There is no cure for lactose intolerance. But you can treat your symptoms by limiting or avoiding milk products, using milk with reduced lactose, or substituting soy milk and soy cheese for milk and milk products. You can also take dietary supplements called lactase products that help digest lactose.
A doctor can usually tell if you have lactose intolerance by asking questions about your symptoms. He or she may also ask that you avoid dairy products for a short time to see if your symptoms improve. Sometimes doctors order tests to see if you are digesting lactose normally.

Lactose intolerance is a problem that makes it hard to digest lactose. Lactose is a type of natural sugar found in milk and dairy products. This condition isn't the same thing as a food allergy to milk.
When lactose moves through the large intestine (colon) without being properly digested, it can cause gas, belly pain, bloating, and diarrhea. Some people who have lactose intolerance can't eat or drink any milk products. Others can eat or drink small amounts of milk products or certain types of milk products without problems.
Lactose intolerance occurs when the small intestine doesn't make enough of an enzyme called lactase. Your body needs lactase to break down, or digest, lactose.
Sometimes the small intestine stops making lactase after a short-term illness, such as a stomach infection, or as part of a lifelong disease, such as cystic fibrosis. Or the small intestine may stop making lactase after surgery to remove a part of the small intestine. In these cases, the problem can be either permanent or short-term.
Lactose intolerance runs in families. Symptoms usually start during the teen or adult years. Most people with this type of lactose intolerance can eat some milk or dairy products without problems.
Some premature babies have temporary lactose intolerance. That's because they aren't yet able to make lactase. After a baby starts to make lactase, the problem often goes away.
