Lactose intolerance is a condition that occurs when the small intestine doesn’t make enough of the enzyme called lactase, according to the National Institutes of Health (NIH).

The enzyme is needed to digest lactose, which is a type of sugar found naturally in milk and other types of dairy products, according to the NIH.

Lactase is able to break down the milk sugar into two simpler kinds of sugar that can be absorbed into the bloodstream, according to the Food and Drug Administration (FDA).

For more information about lactose intolerance, talk with your doctor.
