I've had lupus for 26 years now, and they really don't know what causes lupus, that's why they don't have a cure for it. Joy is correct in with Lupus our bodies basically attacks itself. It looks at our cells and attacks them and makes us sick.
Lupus can be controlled and varies from person to person. Some folks are very mild with their disease and others it's so bad it's life threatening. It can become quite and some folks can even come off all medications for periods of times, but they are NEVER cured of the disease.
The best thing a person can do is make sure that their disease is well controlled. Which may mean medications or not. Plus limiting stress in your life, getting plenty of rest, eating healthy, and if possible getting some exercise. If we don't do these things, then usually a flare up will come on. Lupus can sound overwhelming and it certainly can feel that way a lot of the time. However, you've found a great place here with many people who are willing to listen and help out with advice.
Try to take care and rest and leave the stress behind if you can. If you have any questions, please feel free to ask away. Oh, one other thing, you'll often see many lupus patients also have RA, Sjogrens, Raynauds, and Fibro. All of these conditions aren't the same, but have similar traits, some more than others.
Hang in there and looking forward to getting to know you better.
