Celiac disease affects more than two million people in the United States. This genetic digestive disease begins with exposure to gluten—the protein in wheat, rye and barely—and can be mistaken for a gluten allergy. In the presence of gluten, the immune system of a person with Celiac disease attacks the villi, which line the small intestines absorbing nutrients into the bloodstream during digestion. This immune system reaction can damage or destroy the villi possibly leading to malnourishment. Onset of this disease during childhood can be especially troubling as it may result in stunting of the child’s normal growth and development. Common symptoms with a childhood presentation of Celiac disease primarily have to do with digestion and can include:  abdominal bloating and pain, chronic diarrhea, vomiting, constipation, and weight loss. When Celiac disease presents in adults, the symptoms are typically somewhat different.  They include: anemia, fatigue, numbness in hands and feet, and a skin rash called dermatitis herpetiformis.
