Parts of the body it affects
Explore what each area does and the conditions that can affect it.
Blood & immune system
Blood carries oxygen and nutrients, and white blood cells defend you from infection. In autoimmune disease, that defense system targets your own tissues.
Skin
Your skin is your largest organ and a major immune barrier. Rashes, patches, and color changes are often the first visible signs of an autoimmune condition.
Hair
Hair is often one of the first places to show what's happening inside the body. Changes in shedding or thickness can point to nutrient, thyroid, hormone, or autoimmune causes.
Thyroid
This butterfly-shaped gland in your neck sets the pace of your metabolism. Autoimmune disease is the most common cause of thyroid problems.
