My bood pressure has been high for many years. I tried to loose weight many times but just could not shift it. My BMI was around 32. Two of my Grandparents died of strokes in their late 50's, I'm 58 now. In the end I decided to go on medication, but after around 18 months I decided to come off it because I was having real problems keeping warm. I agreed with my Dr that I would loose weight instead to get the BP down. I've now lost over a stone this year and a stone last year. BMI now around 28, but my BP is going up (170/109 today). Three weeks ago my sister was diagnosed with Wegeners granulomatosis, she is very ill, kidneys almost packed in, on steriods, chemo, dialysis, blood transfusions. When I was looking it all up I discovered that one sign of kidney failure is feeling cold. I have had 3 kidney stones, although the last one was 20 years ago. Recently I did get what seemed like flu: freezing cold, then a few days later a terrible pain in my side. Not sure it was another stone because they are fantastically painfull. Sorry to dump all this one you.
