Detailed explanation-1: -Two hours after drinking a liquid that contains high levels of lactose, you’ll undergo blood tests to measure the amount of glucose in your bloodstream. If your glucose level doesn’t rise, it means your body isn’t properly digesting and absorbing the lactose-filled drink.
Detailed explanation-2: -Secondary lactose intolerance occurs when the gut lining (where lactase is produced) is damaged. This can occur due to a bout of gastroenteritis or due to chronic irritation (such as that due to food allergy or food intolerance), among other reasons.
Detailed explanation-3: -Primary lactose intolerance occurs as the amount of lactase declines as people age. Secondary lactose intolerance is due to injury to the small intestine. Such injury could be the result of infection, celiac disease, inflammatory bowel disease, or other diseases.
Detailed explanation-4: -Secondary lactase deficiency is a shortage of lactase caused by a problem in your small intestine. It can occur at any age, and may be the result of another condition, surgery to your small intestine or taking certain medication.
