Autoimmune disease occurs when your body mistakenly attacks healthy cells, weakening your immune system and leading to inflammation throughout the body. Common types of autoimmune disease include rheumatoid arthritis, lupus, celiac disease, and more. Many doctors prescribe medication to treat symptoms, but never fully resolve them. Because autoimmune diseases can take so many different forms and have different causes, it’s important to determine the cause in order to formulate the best treatment plan. At Parsley Health, we do just that.
