Erythropoiesis-Stimulating Agents (ESAs)

Erythropoiesis-Stimulating Agents (ESAs) are medications that help the body produce more red blood cells, which carry oxygen throughout the body. They are typically used for people with anemia caused by chronic kidney disease or certain treatments like chemotherapy. By boosting red blood cell production, ESAs can alleviate symptoms like fatigue and shortness of breath. They work by mimicking a natural hormone called erythropoietin, produced by the kidneys, to stimulate the bone marrow to make more red blood cells. Proper use requires medical supervision to balance benefits and potential risks.
