Detailed Information on Celiac Disease

Celiac disease is an inherited, autoimmune disease in which the lining of the small intestine is damaged from eating gluten and other proteins found in wheat, barley, rye, and possibly oats.

Celiac disease is a digestive disease that damages the small intestine and interferes with absorption of nutrients from food. People who have celiac disease cannot tolerate a protein called gluten, found in wheat, rye, and barley. Gluten is found mainly in foods but may also be found in products we use every day, such as stamp and envelope adhesive, medicines, and vitamins.

Celiac disease runs in the family. You inherited the tendency to get this disease from your parents. If 1 member of your family has celiac disease, about 1 out of 10 other members of your family is likely to have it. You may have this tendency for a while without getting sick. Then something like severe stress, physical injury, infection, childbirth or surgery can "turn on" your celiac disease.

Celiac disease affects each person differently. Symptoms may occur in the digestive system, or in other parts of the body. One person might have diarrhea and abdominal pain, while another person may be irritable or depressed. Irritability is one of the most common symptoms in children. Some people have no symptoms.

Celiac disease is a digestive condition triggered by consumption of the protein gluten, which is found in bread, pasta, cookies, pizza crust and many other foods containing wheat, barley or rye. Oats may contain gluten as well. When a person with celiac disease eats foods containing gluten, an immune reaction occurs in the small intestine, resulting in damage to the surface of the small intestine and an inability to absorb certain nutrients from food.

The body's inability to absorb nutrients can also mean that young people with untreated celiac disease may not grow properly and may have weight loss and fatigue. In addition, people who have celiac disease may be prone to developing other diseases, such as thyroid disease, type 1 diabetes, and gastrointestinal cancer.

Normally, the body's immune system is designed to protect it from foreign invaders. When people with celiac disease eat foods containing gluten, their immune system forms antibodies to gluten which then attack the intestinal lining. This causes inflammation in the intestines and damages the villi, the hair-like structures on the lining of the small intestine. Nutrients from food are absorbed by the villi. If the villi are damaged, the person cannot absorb nutrients and ends up malnourished, no matter how much he or she eats.

Celiac Disease may appear at any time in a person's life. The disease can be triggered for the first time after surgery, viral infection, severe emotional stress, pregnancy or childbirth. CD is a multi-system, multi-symptom disorder. Celiac Disease symptoms are extremely varied, can often mimic other bowel disorders and are not always gastrointestinal.

Celiac disease is an autoimmune medical condition in which damage to the epithelia (inner lining) of the small intestine occurs following ingestion of a substance called gluten. Gluten is a grain protein used in food processing because it binds, stabilizes, and prevents crumbling. The gluten protein in wheat has a portion called gliadin, which is toxic to people with celiac disease. Barley, rye, and triticale also contain proteins toxic to celiac patients.
