I'm 40 and I just got diagnosed. It makes me wonder how many latent cases are out there. Supposedly 1 in 200 people have it, but I don't know anyone else who is officially diagnosed.
I have a theory that all of the "beer bellies" out there are undiagnosed celiacs. I know plenty of people that drink a lot of beer that don't have "beer bellies." I remember how my stomach would bloat after eating pasta or pizza. Hmm...
It's not something many doctors think of when they here their patients ailments. Too bad, because much like lactose intolerance, a change in diet is all that is needed to clear up the problem.
