I am a 55 year old female who is seriously overweight but trying to lose weight sensibly. I am on HCTZ for my tendency to retain water (have had this tendency since my 20 s when I was not overweight), and to lower my blood pressure, which has been slightly high past few years. This morning, I felt weak, shaky, and had palpitations. My bp was 155/88 and pulse was 88. Rested 30 minutes, then my bp was 166/92 and pulse was 90. My resting pulse is normally around 72. I have a doctor appointment in 2 weeks. Do I need to be seen sooner?
