Lactose Intolerance

Lactose intolerance means that your body can't digest lactose, a sugar found in dairy products. It causes gas, belly pain, and bloating. 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.
