Approximately one out of 115 people get celiac disease, but unfortunately, many people are undiagnosed because the symptoms mask so many other diseases.

"Nausea, vomiting, diarrhea, acid reflux."

Other common symptoms are weight loss, abdominal pain and there are non digestive symptoms as well that make it hard to diagnose.

"They may have headaches, they may have seizure disorders, they can have liver abnormalities, they can have anemia," said Dr. Arthur Ostrov.

This auto-immune disease can show up at any age, a simple blood test is needed to diagnose it. It's set off by products containing gluten.

Ostrov said, "It's something in wheat, barley, rye, it sets off an inappropriate reaction in your body, it attacks you instead of the wheat, barley and rye."

Signs for little ones can be a bit hard to pinpoint.

"Failure to grow, maybe a failure to gain weight, maybe indigestion, reflux," said Ostrov.

Because this disease requires kids to separate their toys and food, it can be very hard on them emotionally.

"Our child has to be in a gluten-free environment. They can't consume any gluten. So is there gluten in crayons? Mmm hmm. Is there gluten in the toy things you write with? Mmm hmm. So you have to make sure that child, if they're using crayons and there is gluten in the crayons, doesn't get the material in their fingers and in their mouths and set off a terrible reaction. So you have to eliminate all those things from the classroom? That is a possibility," Ostrov said.

A gluten-free diet is not easy on the pocketbook and certainly not easy on the kids.

"What about ice cream? They put wheat in ice cream for filler. You're starting to see all these joys children have and young adults have are very difficult. This is not easy to do, and it's expensive. Gluten-free products are very expensive," Ostrov said.
