Question
Anemia commonly occurs in people with chronic kidney disease (CKD)—the permanent, partial loss of kidney function. Anemia might begin to develop in the early stages of CKD, when someone has 20 -50% of normal kidney function. Anemia tends to worsen as CKD progresses. Most people who have total loss of kidney function, or kidney failure, have anemia.
a) What are systemic consequences of kidney failure relative to hematocrit and blood volume?
b) Other common causes of anemia in people with kidney disease include blood loss from hemodialysis and low levels of the following nutrients found in food:
• iron •
vitamin B12 •
folic acid
What is the importance of above nutrients relative to patient’s ability to supply adequate levels of O2 / nutrients to cells (and remove C02 and waste), and subsequently produce ATP?
Explanation / Answer
Answer-a)kidney secreted a hormone called erythropoietin,which stimulate the erythropoiesis process.hemce,help in formation of red blood cells.red blood cells counts will be reduced and patient will become anaemic.there will be hyperdynamic circulation,which can cause damages to the end arterioles and results in stroke and haemorrhage.
Answer-b-as patient of chronic kidney disease is already anaemic,if his diet is deficient in iron,folic acid and vitamin B12.this will further exacerbate the anaemia of the patient.
