An autoimmune disease is a condition arising from an abnormal immune response to a functioning body part. Autoimmunity is the system of immune reactions of a creature against its solid cells and tissues. A disease that results because of this sort of reaction is called an autoimmune disease.
The cause is unknown. Some autoimmune diseases such as lupus run in families, and infections or other environmental factors may trigger certain cases. Some common illnesses that are generally considered autoimmune include celiac disease, diabetes mellitus type 1, graves’ disease, inflammatory bowel disease, multiple sclerosis, alopecia areata, addison’s disease, pernicious anemia, psoriasis, rheumatoid arthritis, systemic lupus erythematosus. Some autoimmune diseases target only one organ. Type 1 diabetes damages the pancreas. Other diseases, like systemic lupus erythematosus or lupus, can affect the whole body.
