First dialysis . You may not feel better immediately after your first hemodialysis session (hd), as it sometimes takes 3 or 4 hd's to feel better. If you have no problem with fluid removal on hd, you should certainly feel better inside of two weeks. Your blood count should be rising as well as you're being given medicine to increase it on dialysis along with medicine to treat your hyperparathyroidism. Good luck.
Tired. Most patients feel fatigued and have lack of energy for 4-6 hours after first dialysis. After a few dialysis sessions most patients have improvement in their apetite and other symptoms.
