There is no current or direct way to prevent lupus from occurring. According to WebMD, avoiding tobacco and smoking can decrease the chance of getting Lupus. People who smoke or use tobacco products are more likely to be diagnosed with Lupus. Chemicals in these products can trigger lupus in the human body of certain people. It may not happen if you use these products daily, but it is better to be safe than sorry.
