I'm five foot six, my weight has always been 8 to 8.5 stone. The few times I've been in hospital for day procedures, they comment on my low blood pressure. I'm an avid hiker and have been doing so for many years. Once every couple of years when hiking up a steep mountain, I have to stop as I feel light headed, just for seconds, and put my head between my legs and then am good to go again. Otherwise it doesn't cause me problems.
Any tips or suggestions?
