A large percentage of people with HIV seem to become lactose intolerant. This happens because the HIV infection changes the structure of the gut wall, resulting in a decreased lactase level. Lactase is an enzyme which is needed to break down lactose.
Lactose intolerance can also be caused by different conditions or even genetics. For example, can be common for people that are lactose intolerant as adults to have African or Asian ancestors.
