Can a person become lactose intolerant later in life?
I'm not sure if I'm just having a weird reaction to milk or is I'm becoming lactose intolerant. For example, when I eat/drink a dairy product I start to get nauseas, start to burp slightly, and possibly get...diarhea. Am I becoming lactose intolerant? Because my GI doctor said a while back to stay away from dairy products and green salads for a little while.
