Lactose intolerance is a common complaint among children and adults. This digestive disorder makes it hard for the body to process lactose, which is found in milk and dairy products. Since the body cannot digest lactose properly, it starts to ferment and release gases.

1. Symptoms at Any Age

Lactose intolerance may first appear in childhood but becomes more common with age. With age, the ability to make the enzyme that breaks down lactose goes down. The cause of the disorder may be a minor infection in the digestive system, and everything returns to normal in under a month. When lactose intolerance develops in later years, it is likely permanent, but it can go away on its own. Most commonly, the disorder develops in people in their 20s or 30s but can come on at any age.
