How Lupus and Other Autoimmune Diseases Affect the Body

Lupus is an autoimmune disease, which means the immune system of people living with the condition doesn’t work as it should. Usually, the immune system is good at spotting foreign invaders — germs, bacteria, and viruses — and killing them off by producing antibodies to fight against them.

Resources.lupus.org explains that antibodies are proteins in the blood which fight off invaders and then create an immunity to the infection.

In people with lupus and other autoimmune diseases, the immune system is unable to distinguish the difference between foreign invaders and healthy tissue so it creates autoantibodies. These turn on the body and begin to attack healthy tissue instead of attacking unwanted germs and bacteria.

These attacks can occur anywhere in the body causing inflammation, meaning people living with lupus can suffer from a myriad of symptoms. When the autoantibodies attack, the person is experiencing a flare; when the autoantibodies are not attacking then the person is considered in remission. Lupus sufferers will go through phases of intermittent flares and remissions.
