Immune diseases occur when the immune system attacks and kills healthy body cells by mistake, notes MedlinePlus. More than 80 immune diseases exist. When a person has an immune disease, the immune system fails to differentiate between harmful antigens and healthy tissues, causing the body to start a reaction that destroys the healthy tissues. The exact cause of immune diseases is unknown. However, there exist different theories; for example, drugs or microorganisms may cause changes that confuse the immune systems. The disorders can result in changes in organ function, unusual growth of organs and destruction of body tissues.

Areas commonly affected by immune diseases include joints, skin, red blood cells, connective tissues, blood vessels and endocrine glands, states MedlinePlus. The symptoms of the disorders vary by type, but common signs include rash, joint pain, ill-feeling, fatigue and fever. The goal of treating immune disorders is to ease symptoms, maintain the body's ability to fight diseases and regulate the autoimmune process. The doctor suggests treatment depending on the type of the disease.
