IMMUNE SYSTEM DISORDERS



Disorders of the Immune System fall generally in three categories:

   • Overactive or inappropriate immune response.

   • Deficient immune response.

   • Autoimmune (self-attacking) response.

Asthma and allergies are examples of an overactive immune system reacting to a non-threatening foreign substance. 

Immune deficiencies (immunodeficiencies) and autoimmune disorders are generally more serious and can be life-altering.
