Lactose intolerance is the inability to digest lactose, a sugar found in milk and other dairy products. It is a very common condition. Lactase is a type of protein called enzyme, located in your digestive tract. It helps breaking down lactose so your body can absorb it. A lactose intolerance happens when you don’t have enough of this enzyme- it can happen naturally with age, due to a genetic deficiency, or temporarily after a of food poisoning, If you have lactose intolerance and you eat a diary product, you will probably suffer from bloating, stomachache and diarrhea.
