Chronic Kidney Disease (CKD)

To keep you healthy, your kidneys are responsible for important functions, such as balancing fluids, regulating blood pressure, producing certain hormones, and removing waste products from the blood.

CKD is defined as a gradual loss of kidney function, which is measured by your estimated glomerular filtration rate (eGFR).

  • eGFR is a number that shows how well your kidneys are filtering. It is based on a blood test, in addition to your age, sex, and body type, as well as other factors

CKD can be caused by many factors, such as diabetes or high blood pressure.

Iron Deficiency Anemia in CKD

Common in patients with CKD, anemia is a condition that occurs when there are not enough healthy red blood cells to carry the oxygen your body needs.


To Make Red
Blood Cells, Your
Needs Iron and
Erythropoietin (EPO)

  • Anemia in patients with CKD is often caused by not having enough iron in your body, or iron deficiency. Not having enough iron can happen if your body isn’t able to absorb iron from food, or if you are losing iron from blood loss
  • EPO is a hormone made by your kidneys that tells your body to make red blood cells. As kidney function declines, the amount of EPO your kidneys make decreases. This reduces the number of red blood cells in your body, causing anemia
