I have no idea why my blood pressure is high. I went to the doctors yesterday at it was 158/100. They put me on water pills for 3 weeks and a low sodium diet . The thing is, I think maybe it could be an underlying issue. Six months ago when i went, it was 112/86. My diet hasnt change too much (I eat fairly healthy), but i only exercise once or twice every two weeks. I am not overweight .. 5 125lb. I have been on birth control for about 3 years. I also have experienced a kidney infection (of both kidneys) and a few uti s. I want to make my bp isn t because of some kind of kidney problem, or possibly diabetes (my grandfather has type 1). What are your opinions?
