Detailed information on autoimmune diseases and pregnancy Autoimmune diseases are conditions in which the body makes antibodies against one's own normal body chemicals. In these diseases, antibodies cannot tell antigens in the inside of the cell from antigens outside of the cell. When the antibodies attack the internal cells, the reactions can be local - in just a small area, or systemic - throughout the whole body. The skin and connective tissues (cartilage, bone, tendons) are most affected but other tissues can be affected, as well, including nerve and muscle.
