Leaky Gut is a term first coined by non-traditional medicine years ago and it was not until late 2014 that traditional medicine started recognizing it as a real problem.
Basically, Leaky Gut exists when the cells lining of the gastrointestinal tract (GI). During leaky gut, these cells separate allowing contents of the GI tract to enter the body between the separated cells. Once these digested particles get between the cells and into the body they are recognized as foreign and are attacked by natural killer white blood cells and their antibodies. Once this occurs, the intestinal tract becomes microscopically inflamed and can result in decreased nutrient absorption and allergies to food consumed. Many believe that this is the root of many autoimmune diseases and allergies. Many believe that many autoimmune diseases originate from the gut.
As you can imagine, this can result in a conglomerate of conditions ranging from food allergies to malnutrition (nutrient deficiencies). Commonly people can complain of fatigue, autoimmune diseases, gas, bloating, abdominal discomfort, diarrhea/constipation, weight gain, decrease mood, cravings (especially bread, sugar, salt) and intolerance to certain foods. These people frequently have positive food sensitivity and allergies tests to many foods.
Correction of this problem utilizes a multiple protocol approach. Often non-traditional FDA approved testing is utilized to help identify and to direct treatment. Leaky Gut is often treatable and the underlying problem can be addressed.
