Lactose Intolerance

What is Lactose Intolerance?

Lactose intolerance is a condition that leads to symptoms due to the inability to fully digest lactose (milk sugar) in dairy products.

Causes of Lactose Intolerance

A deficiency of lactase — the enzyme produced by the lining of your small intestine and important in the digestion of lactose— is responsible for lactose intolerance. Many people have low levels of lactase, but only those who also have symptoms have, by definition, lactose intolerance.

Symptoms of Lactose Intolerance

Symptoms may include abdominal cramping, abdominal bloating, flatulence, or diarrhea. The condition is usually not dangerous, but symptoms of lactose intolerance can be uncomfortable.

Treatment for Lactose Intolerance

You can control symptoms of lactose intolerance by carefully choosing a diet that limits dairy products. You can also take over-the-counter products that contain lactase when you ingest dairy products to minimize symptoms.
