Immune System Diseases and Dysfunction

Immune system diseases can be divided into two basic categories. There are disorders or diseases of the immune system to the body's ability to fight against disease and dysfunction is impaired or immune system disorders in the exaggerated immune system to stimuli, causing damage to other organs or body systems.

There are many congenital and hereditary diseases of the immune system and they are often referred to as primary immunodeficiency diseases. These autoimmune diseases affect about 50,000 people in the United States. A healthy immune system recognizes "invaders" such as viruses, bacteria, or anything that is not a normal part of the body and destroy the invaders. In severe cases of immune diseases, the body may have small normal immune responses, where appropriate ,. These diseases of the immune system results in frequent recurrent infections. Acquired immunodeficiency syndrome (AIDS) is a disease of the immune system that is hereditary or not congenital. HIV invades and inactivates certain immune cells called helper T cells. T helper cells are white blood cells that normally stimulate the production of antibodies and killer T cells that destroy viruses, bacteria and intruders, such as cancer cells. There are many conditions which are believed to be caused by a dysfunction of the immune system and these are sometimes called immune diseases or are grouped with diseases of the immune system for the purpose of discussion. The diseases such as systemic lupus erythematosus, juvenile diabetes onset, multiple sclerosis and psoriasis are all supposed to be associated with a system hyperactivity immune. diseases such as these are characterized by the immune system attacks normal healthy cells for unknown reasons. Allergies believes yet be associated with a dysfunction of the immune system, the immune system overreacts to allergens.

A lot about how the healthy immune system works is unknown. Most of what we know about a healthy immune system that has been learned by studying the immune system diseases. Much of what we know about health supplements that help support and maintain a healthy immune system stems from the study of diseases and efforts to correct immune system.
