What causes lactose intolerance? Our body has the enzyme lactase produced in the small intestine. It breaks down lactose. Which is found in many dairy products, into smaller sizes and is absorbed to use as energy in the body. But the body of a person with lactose intolerance cannot completely digest lactose. This is because the small intestine does not produce enough of the enzyme lactase. When undigested lactose reacts with bacteria in the large intestine. It causes gas and causes bloating and abdominal pain as a result. สมัคร ufabet
