1. What Is an Autoimmune Disease?
An autoimmune disease is a condition in which your immune system mistakenly attacks healthy cells. It should target only foreign organisms, like viruses or bacteria, during an infection. However, autoimmune diseases become confused and cannot differentiate between outsiders and the body’s parts, such as joints, skin, or organs. There are over 100 different types of autoimmune diseases, and they can affect people of all ages, races, and genders, though women are more likely to be affected than men.
