What Is Autoimmunity?
Your immune system, which consists of different types of cells, constantly works to protect you from ‘attacks’ by substances such as viruses and germs. The system recognizes these substances as being foreign and will send particular cells to kill them.
When the system doesn’t work right, however, this process can cause harm. Immune cells can mistake your body’s own cells as invaders and attack them. This ‘friendly fire’ can affect almost any part of the body, sometimes targeting many organs at the same time. This condition is called autoimmunity (meaning self-immunity).
