Lupus is a kind of autoimmune disease wherein the immune system of the body starts getting hyperactive and will attack the healthy and normal tissue. This results in the body going through swelling, damage to the lungs, heart, blood, kidneys, skin, and joints.
Lupus makes the body’s immune system confused and have difficulty differentiating between the healthy tissue and the antigens. This is why it leads the antibodies of the immune system to go against the healthy ones. This doesn’t only pertain to antigens. The good thing about lupus is that it is not contagious.
