Can You Develop Lactose Intolerance Later In Life
Found in milk. Lactose is a large sugar molecule that is made up of two smaller sugar molecules, glucose and galactose. In order for lactose to be absorbed from the intestine and into the body, it must first be split into glucose and galactose. The glucose and galactose are then absorbed by the cells lining the small intestine. The enzyme that splits lactose into glucose ...Read more
Yes, comes with age: The great majority of the world's population becomes lactose intolerant with age (except northern europeans), because people produce less and less lactase enzyme and will not be able to digest milk sugar. Lactose intolerance can come on more suddenly after diarrhea. Taking lactase (lactaid tablets) can help a lot. We humans are the only mammals who keep drinking milk after weaning off the breast. ...Read moreSee 1 more doctor answer

Yes: It's hard to get latex allergy. Nurses develop eczema or contact dermatitis after using latex gloves for years. Later anaphylaxis, severe life-endangering form of allergy, occurs if latex contacts a mucosal surface - like a balloon in your mouth - or during surgery when the surgeon's gloves touches the inside of the body. Kids get it if they require multiple catheterizations for neurogenic bladder. ...Read moreSee 2 more doctor answers

Sudden lactose intol: Defects in lactose absorption can be acquired (due to inflammatory conditions of the intestine*) or congenital.

Congenital lactase deficiency (ar) is acute watery diarrhea in infants. *see your doctor for evaluation if your lactose intolerance is indeed of sudden onset. ...Read more
