Immune disorder
Immune Disorder
An Immune Disorder (pronunciation: /ɪˈmjuːn dɪsˈɔːdər/) is a condition that occurs when the immune system does not function properly. The etymology of the term comes from the Latin word "immunis" meaning "exempt" and the Old French "desordre" meaning "lack of order".
Types of Immune Disorders
Immune disorders can be categorized into three main types:
- Immunodeficiency disorders: These occur when one part of the immune system is missing or not functioning properly. Examples include HIV/AIDS and Severe Combined Immunodeficiency (SCID).
- Autoimmune disorders: In these disorders, the immune system mistakenly attacks the body's healthy cells as if they were foreign invaders. Examples include Rheumatoid Arthritis and Type 1 Diabetes.
- Allergic disorders: These are overreactions of the immune system to substances that usually cause no harm in most individuals. Examples include Asthma and Food Allergies.
Symptoms
Symptoms of immune disorders can vary greatly depending on the specific disorder. However, common symptoms may include:
- Frequent and recurrent pneumonia, bronchitis, sinus infections, ear infections, meningitis or skin infections
- Inflammation and infection of internal organs
- Blood disorders, such as low platelet counts or anemia
- Digestive problems, such as cramping, loss of appetite, nausea and diarrhea
- Delayed growth and development
Diagnosis and Treatment
Diagnosis of an immune disorder typically involves blood tests to see if the immune system responds properly to an infection. Treatment varies depending on the type of immune disorder, but may include medications to boost the immune system, treatments to target specific symptoms or complications, or in severe cases, immunotherapy or stem cell transplant.
