Impaired Immune System
content provided by
Healthwise
The immune system is the body's natural defense system that helps fight infections. An impaired immune system does not work properly and cannot effectively protect a person against infection.
Some conditions and medicines weaken or impair the immune system. These may include:
- Alcohol or drug abuse or withdrawal.
- Certain diseases or conditions. Diabetes, cancer, HIV/AIDS, or conditions in which the body mistakenly identifies its own tissues as harmful (autoimmune disorders) are some examples.
- Chemotherapy or radiation therapy.
- Some medicines, such as corticosteroids or those taken to suppress the immune system after an organ transplant.
- Surgery to remove the spleen (splenectomy).
