lactose intolerance

Milk sugar malabsorption

Lactose intolerance is the inability to digest lactose, a sugar found in milk and dairy products.

People who are lactose intolerant lack sufficient lactase, the enzyme that breaks down lactose, leading to bloating, gas, and digestive discomfort after consuming dairy: I'm lactose intolerant, so I stick to oat milk.

The condition varies in severity—some people can handle small amounts of cheese or yogurt, others avoid dairy entirely.
