Magda, congratulations! I am going on 6 months after kidney transplant and I still have low energy days. I think its great that you are monitoring your vitals, its good info. Just try to remember your kidney is new, trying to acclimate and your body is trying to fight it. None of this is apparent, at least on the surface, but this is a huge deal. Be kind to yourself and try to do things you enjoy. Best wishes!
