Type 1 diabetes, multiple sclerosis, rheumatoid arthritis, lupus, Crohn's disease and psoriasis are some of the most common autoimmune diseases. An autoimmune disease is any type of disease where the body’s immune system attacks healthy cells. None of these diseases have a cure.

They often go undiagnosed for long periods of time because symptoms aren’t always visible and are caused by other common conditions. According to the Autoimmune Association, there are more than 100 autoimmune diseases and 50 million Americans have one or more autoimmune diseases. That is why March is Autoimmune Diseases Awareness month nationally.
