Your immune system is designed to protect your body from harmful bacteria, viruses, parasites, and cancer cells. However, in autoimmune diseases, the immune system mistakenly attacks the body instead of defending it. The exact cause of this malfunction is unknown.
There are over 100 identified autoimmune diseases, with common examples including lupus, rheumatoid arthritis, Crohn’s disease, and ulcerative colitis.
Autoimmune diseases can affect various tissues and nearly any organ, leading to a wide range of symptoms such as pain, fatigue, rashes, nausea, headaches, and dizziness. The specific symptoms vary depending on the disease.
