are characterized by tissue damage and loss of function due to an immune response that is directed against specific organs.
Emerging research shows that most autoimmune conditions may share a common root hiding in the intestinal lining of individuals with autoimmune diseases; a major task of the intestine is to form a defensive barrier to prevent absorption into the bloodstream of damaging substances such as germs, toxins or other large molecules. This protective function of the intestinal mucosa is called permeability. The wall of the intestine is considered a semipermeable. This means the pores only allow certain things to enter the bloodstream and block other things.
Leaky gut syndrome is a proposed condition some health practitioners claim is the cause of a wide range of long-term conditions including Hashimoto's thyroiditis, chronic fatigue syndrome and multiple sclerosis.
When someone has leaky gut (increased intestinal permeability) proteins like gluten, bad bacteria, undigested foods particles and toxic waste are allowed make their way into the bloodstream causing an immune reaction.
Many things have been shown to increase intestinal permeability including gastrointestinal infections, medications such as aspirin or ibuprofen, liver disease, pancreatitis, inflammatory bowel disease and celiac disease.
