Lately when I drink milk or eat dairy products, I get an upset stomach. I?m 30 and have never had a problem like this before. Could I have become lactose intolerant all of the sudden? Answer
Theoretically, you can become lactose intolerant at any point. While it is true that most people show their intolerance to lactose early in life, people can get it in their teenage years, or even in adulthood. Lactose intolerance is caused by a deficiency in the enzyme lactase in the inner lining of the GI wall. See a doctor who can help

Since the GI track cannot absorb lactose whole (it must be broken down), it stays in the gut.
