Ask a Scientist: Can Adults Suddenly Develop Lactose Intolerance?
Content: Most people experience a gradual decline of lactase (the enzyme that helps your body digest milk products) activity as they age. Lactase is produced by the cells lining your small intestine, and if they don’t produce enough, the lactose you consume passes undigested into the large intestine. There, it interacts with bacteria and causes all those nasty stomach problems — diarrhea, gas, bloating — that those with lactose intolerance know all too well. Lactose intolerance could be caused by anything that disrupts the functioning of the small intestine — for example, surgery, an illness such as Crohn’s disease or even food poisoning. Sometimes the intolerance is temporary and resolves itself; other times, it’s permanent. For some, the natural lactase decline happens quicker and more drastically, causing intolerance that was never there before. Advertisement
If dairy isn’t sitting as well with you as it used to, try this self-test: stop consuming dairy products for five days, and on the sixth day, drink a glass of milk. If your symptoms resolve during the dairy-free days and come back when you reintroduce it, you most likely have developed lactose intolerance.
