Celiac Disease or also known as Sprue, gluten intolerance and sensitivity, actually has many different types of symptoms. Some include gas, diarrhea, nausea, fatigue, hair loss, anemia, depression, joint pain, weight loss, and even skin rashes and osteoporosis. What the disease actually does is damage the lining of the small intestine and prevents it from absorbing food properly. The body reacts to gluten which is a protein found in wheat, rye and barley. Celiac Disease tends to be genetic but can occur in those without a family history.
