Autoimmune diseases occur when the bodys immune system attacks and damages its own tissues, mistaking them for foreign invaders. There are over 80 known autoimmune diseases, and some of the most common ones include:

• Rheumatoid arthritis (RA): This is a form of arthritis that attacks the joints, causing inflammation, swelling, and pain.
• Systemic lupus erythematosus (lupus): This is a chronic autoimmune disease that can affect various parts of the body, including the skin, joints, kidneys, and brain.
• Inflammatory bowel disease (IBD): This is a group of inflammatory conditions that affect the digestive tract, including Crohns disease and ulcerative colitis.
• Multiple sclerosis (MS): This is a chronic autoimmune disease that affects the central nervous system, causing symptoms such as fatigue, muscle weakness, and difficulty with coordination and balance.
• Psoriasis: This is a skin condition marked by thick, scaly patches of skin.

Autoimmune diseases can affect many types of tissues and nearly any organ in the body, and they may cause a variety of symptoms including pain, fatigue, rashes, nausea, headaches, and dizziness. Some autoimmune diseases are easily treated, while others can last a lifetime. There is no known cure for autoimmune diseases, but treatments aim to manage symptoms and may include medications, supplements, and physical therapy.
