A disorder in which the body’s immune system fails to identify and targets its own healthy tissues as invading. Inflammation is a common symptom of autoimmune diseases, and it can affect many different regions of the body. The body parts affected differ based on the type of autoimmune condition a person suffers.

Fatigue, fever, muscular aches, joint pain and swelling, skin problems, gut pain, digestive problems, and swollen glands are all common indications and symptoms. Symptoms might be mild or severe, and they come and go. Autoimmune disorders come in many different types. Women are more likely to develop them, and they can run into families. Also known as an immune deficiency.

What are Autoimmune Diseases?
A disorder in which your immune system mistakenly targets your body is known as autoimmune disease.
Normally, the immune system protects us against pathogens such as bacteria and viruses. It sends out an army of fighter cells to attack these foreign invaders when it detects them.
However, your immune system is able to distinguish between foreign invading and native cells.
The immune system misidentifies parts of your body, such as your joints or skin, as external in autoimmune disease. Autoantibodies are proteins released by the body that assault healthy cells.
Immune system disorders result in abnormally low or excessive immune system activity. Overactive immune systems cause the body to attack and destroy its own tissues (autoimmune diseases). Immune deficiency disorders reduce the body’s ability to fight against intruders, making it more susceptible to infection.
The immune system may produce antibodies that, instead of defending infections, attack the body’s own tissues in reaction to an unknown stimulation.
