Celiac disease, also known as gluten intolerance, is a genetic disorder that affects at least 1 in 133 Americans. Symptoms of celiac disease can range from the classic features, such as diarrhea, weight loss, and malnutrition, to latent symptoms such as isolated nutrient deficiencies but no gastrointestinal symptoms. The disease mostly affects people of European (especially Northern European) descent, but recent studies show that it also affects Hispanic, Black and Asian populations as well. Those affected suffer damage to the villi (shortening and villous flattening) in the lamina propria and crypt regions of their intestines when they eat specific food-grain antigens (toxic amino acid sequences) that are found in wheat, rye, and barley. Oats have traditionally been considered to be toxic to celiacs, but recent scientific studies have shown otherwise. This research is ongoing, however, and it may be too early to draw solid conclusions.

Based on the figure mentioned above we can extrapolate the total number of people in the United States with celiac disease: 2.18 million (based on the total population: 290,356,028). It is very important that doctors understand just how many people have this disease so that routine testing for it is done to bring the diagnosis rate in line with the diseases epidemiology. Testing is fairly simple and involves screening the patients blood for antigliadin (AGA) and endomysium antibodies (EmA), and/or doing a biopsy on the areas of the intestines mentioned above, which is still the standard for a formal diagnosis.

The only acceptable treatment for celiac disease is strict adherence to a 100% gluten-free diet for life. An adherence to a gluten-free diet can prevent almost all complications caused by the disease. A gluten-free diet means avoiding all products that contain wheat, rye and barley, or any of their derivatives. This is a difficult task as there are many hidden sources of gluten found in the ingredients of many processed foods. This site is designed to help people with celiac disease get diagnosed, and make life easier after their diagnosis. Those who are interested can read the story of my diagnosis.
