Erythropoietin, a component that promotes the production of red blood cells. Erythropoietin increases significantly when there is a significant decrease in hemoglobin and red blood cells. The first thing to do is to check the blood count for anemia. Patients with anemia should have a reasonable diet and should not be partial. Eat more pig blood, pig liver, lean meat, soy products, dairy products, rice, apples, green vegetables, etc. In addition, you can eat fruits and vegetables that can promote the absorption of iron. After the anemia is corrected, erythropoietin will also be significantly decreased. There is also renal anemia, erythropoietin can be applied to promote the increase of hematopoietic components. In addition, for thalassemia, erythropoietin can also be applied.
