Can you suddenly become lactose intolerant?

Content: For many people, their body can stop producing as much lactase as it did when you were younger. There is Primary lactase deficiency in which Decreased amount of lactase production can begin as early as age 2. For many people this is genetic, and if your parents are lactose intolerant, you may be as well. Secondary lactase deficiency is when there is another digestive issue that is creating the problem. Untreated celiac (genetic, autoimmune disease) destroys the tips of the villi where lactase is produced, Chron's, IBS (lactase can be washed away by constant diarrhea as well) are always suspected until proven otherwise with sudden onset of symptoms like you are having. So basically, if you add lactose back in and your symptoms get worse, yes, you need to see a doctor about it. They will want to make sure that your lactose intolerance is not celiac disease, and not the beginning of any other inflam. bowel issue. The level of lactose tolerance/amount of lactase produced varies from person to person. I am abe to tolerate very small amounts (in some medications and a very limited amount of yogurt or cheese) of lactose, but not much.
