What is the most common type of autoimmune disease?

Autoimmune diseases are a group of disorders in which the immune system mistakenly attacks the body's own cells and tissues. The most common type of autoimmune disease is Hashimoto's thyroiditis, which is a condition that affects the thyroid gland. It occurs when the immune system attacks the thyroid gland, causing inflammation and damage to the gland over time. This can lead to an underactive thyroid (hypothyroidism), which can cause symptoms such as fatigue, weight gain, and depression.

Other common autoimmune diseases include:

• Rheumatoid arthritis: a chronic inflammatory disorder that affects the joints
• Lupus: a chronic inflammatory disease that can affect many parts of the body, including the skin, joints, kidneys, and brain
• Type 1 diabetes: a condition in which the immune system destroys the cells in the pancreas that produce insulin
• Celiac disease: a digestive disorder in which the immune system attacks the small intestine in response to gluten

If you suspect that you have an autoimmune disease, it's important to see a doctor for diagnosis and treatment. Treatment may include medications to suppress the immune system and reduce inflammation, as well as lifestyle changes to support overall health.
