Gluten intolerance is more common than you might think. Mostly, people do not even know that they have the problem at all. This is because there are varying degrees of symptoms associated with this health problem. The reality is, it is not a health problem at all if the gluten containing foods are avoided entirely. Different sets of symptoms arise for different people. What is a symptom for one is not for another. At the same time, you should remember that many of the symptoms for gluten intolerance can also be a sign of other health problems. In any case, if you are experiencing digestive or skin problems when you eat certain foods, you should seek the help of a physician to identify what the real problem is. As long as it is something you can avoid, you should do so. Common symptoms of gluten allergy and complete intolerance (celiac disease) include diarrhea, constipation, rashes such as dermatitis herpetiformis, swelling and water retention, increased heart-rate after eating wheat or other gluten containing foods, multiple allergies, and a weak immune system. This is just to name a few. One of these does sound particularly scary and that is dermatitis herpetiformis. First of all, understand that this issue is a serious condition of the skin, but it is not at all caused by any virus and is not contagious. It does look very similar to contact dermatitis, such as what you would get if you came in contact with poison ivy or poison oak. Instead, it will last much longer, never seeming to go away. In that case, the best thing to do is avoid any and all gluten containing foods. The reason that dermatitis herpetiformis occurs is due to an auto-immune reaction that the body takes on. This is when the immune system recognizes normal bodily tissues as foreign. Immune cells begin to attack such organs like the skin. Skin is the largest organ in the body and directly related to the intestines. When you have any of these symptoms, first go and see your primary care physician. There are other conditions which can cause the same symptoms. The doctor may refer you to a specialist such as a gastrointestinal doctor or an allergist just to be sure.
