Content: Types of lactose intolerance
There are three main types of lactose intolerance, each with different causes: Primary lactose intolerance (normal result of aging)
This is the most common type of lactose intolerance. Most people are born with enough lactase. Babies need the enzyme in order to digest their mother’s milk. The amount of lactase a person makes may decrease over time. This is because as people age, they eat a more diverse diet and rely less on milk. The decline in lactase is gradual. This type of lactose intolerance is more common in people with Asian, African, and Hispanic ancestry. Secondary lactose intolerance (due to illness or injury)
Intestinal diseases such as celiac disease and inflammatory bowel disease (IBD), a surgery, or an injury to your small intestine can also cause lactose intolerance. Lactase levels may be restored if the underlying disorder is treated.
