|The immune system normally protects the body from infections and disease brought about by bacteria, viruses, germs, or abnormal body cells. When an autoimmune disease develops, the immune system mistakenly attacks and destroys its own tissues and organs.
Many parts of the body such as the red blood cells, blood vessels, connective tissues, digestive system, endocrine system, muscles, joints, nerves and skin may be affected. Autoimmune diseases predominantly affect women, frequently during their childbearing years. These diseases often tend to be hereditary, and certain environmental factors may also contribute to a weakened immune system.
Autoimmune disease symptoms vary from individual to individual, with each disease being different. Ranging from mild symptoms to more debilitating conditions, a malfunction of the immune system occurs in all of them.
