Immune Disorders

Although most diseases the immune system tries to fight, there are a few diseases where it is exactly this fight that causes the disease. Sometimes the immune system does too much. Some examples of diseases from an over-reacting immune system include:

• Asthma: an allergic over-reaction that causes the inflammation of airway muscles and mucus membranes lining the airways.
• Allergies - allergic reactions to substances can be harmful in themselves.
• Delayed hypersensitivity - an allergic reaction, caused by immune system T-cells, occurs after days or weeks
• Anaphylactic shock
• Autoimmunity: a special type of immune over-reaction is that in autoimmune diseases.
