Lactose Intolerance

This entry is adapted from the peer-reviewed paper https://medlineplus.gov/genetics/condition/lactose-intolerance

Lactose intolerance is an impaired ability to digest lactose, a sugar found in milk and other dairy products. Lactose is normally broken down by an enzyme called lactase, which is produced by cells in the lining of the small intestine.
