Overview
Lactose intolerance is the term used to describe a decline in the level of lactase, an enzyme needed for proper metabolization of lactose (a sugar that is a constituent of milk and other dairy products), in human beings.
Classification
There are three major types of lactose intolerance.[1] They are primary lactose intolerance, secondary lactose intolerance and congenital lactase deficiency.
Epidemiology and Demographics
An estimated 70%[2] of adult humans are considered lactose intolerant, it is uncommon in healthy northern westerners and a few others groups.
