My father is 84 years old, type 2 diabetic, triple bypass at 60 and also has 4 stents. I am concerned about his blood pressure which has been running around 120/55 and a pulse of 60. He is cold all of the time, he feels like he has to urinate but nothing comes out and also has lost his appetite. We have to force him to eat something. HIs blood sugars have been normal and taken daily. He had bladder cancer 3 years ago but just had a scope done 2 weeks ago and everything was clear. I was wondering with being cold, no fever and no urination if he has a UTI.
