Ok,,keep in mind im not a doc. I do have kidney disease though and do understand the pain and the levels.
My concern is that she is bleeding somewhere. Low platelet count is norm with dialysis patients,,and anemia.Butttttttttttttt transfusions of blood with black stool tells me there is some internal bleeding going on!!!!!!!!!
As soon as possilbe directly ask for her to be checked for internal bleeding.....Stomach, colon,,etc.
Remember,,,,,,,,,they can treat diff issues,,but if they do not find underlying problem,,its all in vain!
Yes it is normal for a dialysis patient to recieve blood transfusions. The kidneys help produce red blood cells and without kidneys, the blood count drops.Even if you take your Epo or whatever it is your mom takes to stimulate her blood production.It could be medication causing the black stools. But it is always advisable to ask a doctor about internal problems. I will pray for your mom and her health.
