Lactase deficiency

Lactase deficiency is a condition in which the body is unable to fully digest lactose, a sugar found in milk and other dairy products. This is due to a shortage of the enzyme lactase in the body.

Symptoms

The symptoms of lactase deficiency usually occur 30 minutes to two hours after eating or drinking foods that contain lactose. Common symptoms include nausea, cramps, bloating, gas, and diarrhea.

Causes

Lactase deficiency is caused by a shortage of the enzyme lactase in the body. This enzyme is produced in the small intestine and is needed to break down lactose into two simpler forms of sugar, which can then be absorbed into the bloodstream.

Diagnosis

Diagnosis of lactase deficiency may involve a lactose tolerance test, a hydrogen breath test, or a stool acidity test. These tests can help determine if the body is properly digesting lactose.

Treatment

Treatment for lactase deficiency typically involves dietary changes. This may include avoiding foods that contain lactose, using lactase products to help digest lactose, or consuming lactose-reduced milk and milk products.
