My son was diagnosed at 12 years old with Celiac Disease. He had stopped growing and lost weight. His sister two years younger than him was taller and weighed almost as much. He had headaches and stomach issues for about 2 years before that. People with Celiac also have a compromised auto immune system for life. There is no cure for this and those over the counter meds to help are worthless.
First 24 hours of gluten free and the headaches stopped. He is now 20 and weighs 230 lbs and is 6'4. Being gluten free made a difference for him.
After 8 years of reading, speaking with doctors, specialists, etc, I agree with what many are thinking.
Celiac has been around for much longer than we know but the increase of people with Celia or are gluten intolerant may be caused by genetically modified foods and wheat.
We were told of a test done using wheat grown in the 70s vs today's wheat and people with Celia were able to eat the flour from the 70s but became sick on today's.
