What is Celiac Disease?
Celiac Disease is an inherited autoimmune disease that effects more than 3 million Americans. The disease affects the digestive process of the small intestine and is triggered by the consumption of gluten--a protein found in wheat, barley and rye. Celiac Disease causes an abnormal response to gluten ingestion: the immune system attacks the small intestine, inhibiting the absorption of important nutrients, destroying the intestinal villi and wreaking havoc on body systems.
Celiac disease is an inherited autoimmune disorder that affects the digestive process of the small intestine. The small intestine is connected to the stomach-the first parts of the small intestine, the duodenum and the jejunum, are where celiac disease is commonly found.
When a person who has celiac disease consumes gluten, a protein found in wheat, rye and barley, the individual immune system responds by attacking the small intestine and inhibiting the absorption of important nutrients into the body.
Specifically, tiny fingerlike protrusions, called villi, on the lining of the small intestine are lost. Nutrients from food are absorbed into the bloodstream through these villi. Celiac disease can be associated to other autoimmune disorders and, undiagnosed and untreated, it can lead to osteoporosis, infertility, neurological conditions and in rare cases, cancer.
What is Dermatitis Herpetiformis?
Dermatitis herpetiformis (DH) is an itchy, blistering skin condition that is a form of celiac disease. The rash usually occurs on the elbows, knees, and buttocks and is characterized by its bilateral nature; both knees (and/or both arms) are affected, seldom just one. Many people with DH have no digestive symptoms and only about 40% of them have the positive blood tests (serology) for celiac disease: however, they almost always have the same, gluten-dependent intestinal damage as people with celiac disease.
Unless otherwise specified, the information pertaining to celiac disease also pertains to people with dermatitis herpetiformis. In addition to following a strict gluten free diet, DH is also commonly treated with a medication called Dapsone.
Is Celiac Disease a rare condition?
No. Celiac disease affects more than 1% of the American population, or about 3 million people in the United States. By comparison, Alzheimers disease affects approximately 2 million people. It is possible to be diagnosed with celiac disease at any age.
Is it possible to have Celiac Disease and no Symptoms?
Yes. Recent research has demonstrated that a significant percentage of children and adults with positive celiac blood tests, even when proven celiac by the biopsy, had no or minimal symptoms when they were tested. Further, there are a few patients that carry the gene for celiac disease, have no or minimal symptoms and negative blood tests, yet a positive biopsy showing that the disease is active.
Why is it difficult to find a doctor who knows about Celiac Disease?
Most physicians learned during medical school that celiac disease was so rare they would never see a patient with symptoms in their entire medical career. Lectures on celiac disease in medical schools, even today, are few and far between. When your doctor was in medical school, he or she may have heard a 20-30 minute celiac disease lecture during four years of classes. Medical textbooks still contain outdated information.
Additionally, celiac disease often presents with seemingly unrelated symptoms, such as fatigue, joint pain, anemia and infertility, making diagnosis that much more difficult.
