What hormone is commonly used to treat anemia in patients with kidney disease?

Erythropoietin is the correct choice because it is a hormone that stimulates the production of red blood cells in the bone marrow. In patients with kidney disease, the kidneys often do not produce enough erythropoietin, leading to anemia. When kidney function declines, the decreased erythropoietin production results in a reduced capacity to generate red blood cells, which can cause fatigue and weakness due to lower levels of hemoglobin and subsequent reduced oxygen delivery to tissues.

Treating anemia in such patients typically involves administering erythropoietin analogs, which can restore red blood cell production to a more normal level. This treatment is vital for improving the quality of life in patients suffering from anemia associated with chronic kidney disease.

Other options such as calcitriol, insulin, and adrenaline do not play a direct role in stimulating red blood cell production or addressing anemia related to kidney disease. Calcitriol is involved in calcium metabolism and bone health, insulin regulates blood glucose levels, and adrenaline is primarily involved in the body’s fight-or-flight response. Thus, their functions do not address the specific issue of anemia caused by inadequate erythropoietin levels.
