Can lactose intolerance recover on its own?

Lactose

intolerance is a condition caused by a lack of lactase in the body that breaks down lactose in dairy products. It can be divided into primary lactase deficiency, secondary lactase deficiency, and congenital lactase deficiency. In infants with primary lactase deficiency and congenital lactase deficiency, lactose intolerance persists and generally does not recover on its own. For secondary lactase deficiency caused by infection factors, inflammatory factors and other small intestinal mucosa damage, lactose intolerance will gradually improve over time after controlling the primary factors.
