Why do people get Lactose Intolorance?
Question:
Answers:
Lactose intolerance is caused by the inability of the digestive system to break down lactose into glucose. We also know that the protein (enzyme) responsible to break down lactose into glucose is called lactase. Therefore, the lack of lactase causes lactose intolerance. However, different persons may have different amounts of lactase produced. For instance Peter may be producing just enough lactase to cope with a glass of milk in the morning before suffering any effects while Jane is not even able to have a lick of ice-cream because it distresses her. Some of the causes of lactose intolerance are known. The production of the enzyme lactase can be hindered by certain digestive diseases and injuries to the small intestine. In some cases, children are born without the ability to produce lactase. However, in most cases lactase deficiency develops naturally over time when after about the age of 2 years, the body begins to produce less lactase. Interestingly, most people do not experience symptoms until they reach an older age.
