How do you know that have celiac disease?

Celiac disease is an autoimmune disorder that affects the digestive system. It is caused by a reaction to gluten, a protein found in wheat, rye, and barley. When someone with celiac disease eats gluten, their immune system attacks the lining of their small intestine. This can cause a variety of symptoms, including:

* Digestive symptoms: bloating, gas, abdominal pain, diarrhea, or constipation

* Weight loss

* Iron deficiency anemia

* Fatigue

* Skin rashes

* Infertility

* Neurological problems

* Dental problems

Celiac disease is often diagnosed with a blood test that looks for antibodies to gluten. If the blood test is positive, the doctor may order an endoscopy to confirm the diagnosis. An endoscopy is a procedure in which a small camera is inserted into the small intestine to look for damage.

If you think you may have celiac disease, it is important to see a doctor for testing. Early diagnosis and treatment can help to prevent serious complications.
