Lactose intolerance can be inherited

Is lactose intolerance hereditary?


Is lactose intolerance hereditary?

Good evening!

A distinction is made between different forms of lactose intolerance, the primary (genetic) and the secondary (acquired) form.
About 3/4 of the world's population "suffer" from the primary form, especially in Asia and Africa, a large proportion of people can no longer tolerate lactose after they are young. This shows that it is not a disease, but a completely normal phenomenon. The fact that so many people in our regions can tolerate lactose for life is due to a mutation in the corresponding gene trait.
If both parents have primary lactose intolerance, the child will also develop lactose intolerance. The first symptoms are usually to be expected in preschool age at the earliest; with increasing age, the activity of lactase (the enzyme that breaks down lactose) decreases more and more. It makes sense to give lactose regularly as long as there are no symptoms.
