Lymphopenia

Lymphopenia is a condition where the body has fewer lymphocytes, a type of white blood cell crucial for fighting infections and supporting the immune system. This reduction can result from infections, certain medical treatments, autoimmune diseases, or other health issues. When lymphocyte levels are low, the body's ability to defend against viruses, bacteria, and other pathogens may be compromised, increasing the risk of illness. Lymphopenia is diagnosed through blood tests and can vary in severity and cause, requiring medical evaluation to determine its underlying reason and appropriate management.
