Immunosuppression refers to a condition or process that reduces the effectiveness of the body's immune system. This can occur intentionally, as in medical treatments, or unintentionally due to various diseases or environmental factors. When the immune system is suppressed, the body is less able to fight off infections and diseases.

Medically induced immunosuppression is a cornerstone of several treatments. For organ transplant recipients, immunosuppressant medications are crucial to prevent the immune system from rejecting the new organ, which it perceives as foreign. Similarly, in autoimmune diseases, where the immune system mistakenly attacks the body's own tissues, immunosuppressants are used to calm this aberrant immune response. Cancer chemotherapy also often leads to immunosuppression as a side effect, as these drugs target rapidly dividing cells, including those of the immune system.

Unintentional immunosuppression can arise from a variety of causes. Certain viral infections, most notably HIV/AIDS, directly attack and destroy immune cells, severely compromising immune function. Malnutrition, chronic stress, and aging can also weaken the immune system. Exposure to certain toxins or radiation can further suppress immune responses. Individuals with compromised immune systems are at a significantly higher risk of developing opportunistic infections, which are infections caused by pathogens that typically do not cause illness in people with healthy immune systems. Monitoring and managing the immune status of individuals is therefore important, especially when they are undergoing treatments that induce immunosuppression.
