What Is Hypolactasia?

Link To Other Conditions

Hypolactasia occurs when the body doesn't produce enough lactase to break lactose down into digestible sugars, leading to cramping, bloating, nausea, gas, and diarrhea. Though hypolactasia is best known for causing lactose intolerance, it may have a link to other conditions as well. Certain conditions increase an individual's risk of developing hypolactasia. In rare cases, infants can inherit a genetic inability to create any lactase whatsoever. This can be serious, since infants receive all of their nutrition from milk. For a child to be affected by the disease, both the father and mother must pass on a gene for it. There's also secondary lactose intolerance, which occurs when the small intestine stops producing as much lactase following a certain illness. Some individuals experience this after surgeries or injuries to the small intestine. Crohn's disease, bacterial overgrowth, and celiac disease are all conditions that can lead to secondary hypolactasia.
