Lactose intolerance is the inability of grown-ups and kids to digest lactose, a sugar found in milk and other dairy products, bringing about symptoms. It is because of a lactase deficiency, or hypolactasia. In some (uncommon) cases, children have inherent lactase deficiency, which keeps them from having the capacity to digest human milk. Symptoms include abdominal bloating and cramps, flatulence, diarrhea, nausea, borborygmi, and vomiting (especially in young people). This can be seen after one-half to two hours of consumption. Lactose intolerance may be hereditary or environmentally induced.
Italy 68 % of people are lactose intolerant. Treatment: Limit the amount of milk and milk products in your diet. Most people can have about 10 g of lactose each day. This can be a glass of whole, low-fat, or fat-free milk, for example. All milk contains the same amount of lactose.
