The cause of lupus is not certain, but most scientists consider it to be a genetical issue. However, genes are not the only factor in determining who gets lupus. There are several factors which might trigger the disease.

So what is lupus? It happens when something goes wrong with the immune system. Instead of warding off foreign substances present in the body, the immune system launches an attack on healthy cells and tissues and damaging them which in turn results in illness.

This reversal in the process might be the cause of damage in several parts of the body. The parts that are often affected are joints, skin, heart, lungs, kidney, digestive system and blood vessels. Lupus is of several kinds, and thus the manifestation of the symptoms of lupus may vary in different people. Though the disease can affect any gender, women get it more often than men.
