I presume that you meant on Lupus. Well first of all this is autoimmune disorder and this means that your autoimmune system becomes hyperactive and the result is attacking healthy tissue and cells.
Unfortunately this action has really nasty results such inflammation, swelling, and damage to joints, skin, kidneys, blood, heart and lungs.
Furthermore there are few types of lupus but the most common one is SLE which means systemic lupus erythematosus. This type of lupus can be pretty severe because it can attack any type of the body anytime.
Unfortunately there is no cure for lupus. But early diagnosis of this disease can be really helpful in controlling the disease and its symptoms. I hope this satisfy your curiosity.
