What is an impaired immune system?

A Answers (1)

  • AHealthwise answered

    The immune system is the body's natural defense system that helps fight infections. An impaired immune system does not work properly and can't 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).
