Digestive System Disease-Celiac Disease

Celiac disease occurs when the body’s immune system reacts to a type of protein called gluten. If a person eats food that contains gluten, the immune system will gradually damage the lining of the small intestine. When the small intestine is damaged, it is difficult for the body to absorb vitamins, minerals and other nutrients from food. This can affect young childrens' overall health and growth. More than 2 million people in the United States have Celiac Disease. 

Some symptoms of celiac disease are:

abdominal bloating and pain

chronic diarrhea

vomiting

constipation

pale, foul-smelling, or fatty stool

weight loss

fatigue

irritability and behavioral issues

dental enamel defects of the permanent teeth

delayed growth and puberty

short stature

failure to thrive

Attention Deficit Hyperactivity Disorder (ADHD)

Gluten is found in rye, barley and all forms of wheat, including durum, semolina, spelt, kamut, einkorn and faro. Gluten is also found in some non-food products, such as stamp adhesive (glue) and some medicines.

Celiac disease cannot be cured, but it can be treated by following a gluten-free diet.
