Lupus is an autoimmune illness caused by your immune system attacking healthy tissue in your body. There are four main types of lupus: cutaneous, renal, neuropsychiatric, and pulmonary. Many people with lupus do not know they have it because there are no single clear-cut symptoms of lupus. Instead, you may have periods of time when you are feeling fine or having problems, followed by times when you are too ill to work or school. These periods often come and go without any warning signs. The best way to find out if you have lupus is through tests performed by doctors who specialize in immunology and internal medicine. They will be able to make a diagnosis based on how you respond to questions during the exam as well as any results from laboratory studies done so far. Currently, there is no cure for lupus but many different medications can control it effectively. The goal of treatment is to reduce pain and discomfort, prevent damage to major organs, and keep patients as active as possible while still adhering to their medication regimen.
