<human>: My doctor says I have an autoimmune disease. What does this mean?
<bot>: An autoimmune disease is a condition in which your immune system mistakenly attacks healthy cells and tissues in your body, causing inflammation and damage to the affected areas. Autoimmune diseases are complex conditions that can affect many different parts of the body, including the skin, joints, digestive tract, blood vessels, and endocrine glands. Common symptoms may include fatigue, fever, joint pain, rash, or other physical complaints. Treatment for an autoimmune disorder usually involves medications to reduce inflammation and suppress the immune response. In some cases, surgery or lifestyle changes may be recommended as well.
