Autoimmune diseases occur when the immune system mistakenly attacks the body's own tissues. Common symptoms include fatigue, low-grade fever, muscle and joint pain, and difficulty concentrating. Specific symptoms can vary depending on the disease but may include numbness, dry eyes, hair loss, and heart palpitations. Genetics play a significant role in the risk of developing an autoimmune disease. Environmental factors such as infections, certain foods, and toxins can also trigger these diseases. Managing autoimmune diseases often involves a combination of dietary changes, avoiding known triggers, and following medical advice.
