Lactose intolerance

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.
