Hi,my mom has been receiving hemodialysis for the past two years, well tolerated. recently she has developed, upset stomach, bulging, black stool and H&H has dropped. Started on pepcid but has developed palpatations while taking it. NP at dialysis will start epogen shot for anemai, but I am wondering if she should be considered for a endoscope to rule out GI bleed, she has never had GI disorders in the past. but what concerns me is the corelation with the H&H dropping this past month, (which they did consider a blood transfusion if need be) and the bulging and gi upset, and most of all black stook but never any blood noted). What do you think, Thanks
