What causes lactose intolerance?
Lactose intolerance is caused by too little of the enzyme lactase. If your body does not produce enough lactase, lactose will not be broken down and absorbed into your body. At this point, bacteria in your body will break down lactose using a fermentation process. This causes bloating, gas and diarrhea.
