I've been diagnosed with an autoimmune disease. What is it?

That’s a tough one. There are many different types of autoimmune diseases, and they can be caused by many different things. The most common type of autoimmune disease is called rheumatoid arthritis, which affects about 1% of the population. It causes inflammation in the joints, and it can cause joint pain, swelling, stiffness, and loss of function. Other autoimmune diseases include lupus, multiple sclerosis, celiac disease, and psoriasis.
