So at least for now, there is no cure available for autoimmunity—once you have it, you need to deal with it. To alleviate pain and inflammation, generally autoimmune diseases are treated with a variety of medication that suppresses the immune system, particularly inflammation, which as you may imagine, is not great either. It may alleviate the symptoms of autoimmunity by making the immune system weaker and less likely to attack the body but it also leaves the patient more vulnerable to infections.
