An immune system is a group of cells and substances that fight infection-causing organisms like bacteria and viruses. An autoimmune condition arises when a person's immune system erroneously targets their own body tissues as foreign, such as the skin or joints. As a result, it produces proteins known as autoantibodies, which assault healthy cells. Autoimmune illnesses are roughly classified into two types. 'Organ-specific' illnesses affect just one organ, whereas 'non-organ-specific' disorders impact numerous organs or bodily systems.

Women are more vulnerable than males for unknown reasons, particularly throughout their reproductive years. Sex hormones are assumed to be at least partially to blame. Although there is no treatment for autoimmune illnesses, the symptoms can be treated.

• Muscle ache, joint ache, or weakness
• Insomnia, weight loss, heat sensitivity, or a fast heartbeat are all symptoms of a cardiac condition.
• Recurrent rashes or hives, sun sensitivity, and a butterfly-shaped rash over the nose and cheeks are all symptoms.
• Hair loss, as well as white areas on the skin and within the mouth
• Mouth, eyes, or skin that is parched
• Numbness and tingling in the feet or hands
• Concentration problems
• Pain in the abdomen, blood or mucus in the stool, or diarrhoea
• Ulcers in the mouth
• Clots in the blood
• Miscarriages on many occasions

Treatments for autoimmune illnesses cannot cure them, but they can control the excessive immune response. Among the drugs used to treat these illnesses are:

• Nonsteroidal anti-inflammatory medications
• Immunosuppressive medications
