I'm 39 and have had borderline high blood pressure for years. The irony is that I have an autoimmune disorder which in theory leads to low pressure. My endo theorised that one my meds might be bumping the blood pressure up a little too high, but I need it at this dose to ensure my renin levels are good, so what can you do? On the other hand, high blood pressure also seems to be genetic on my mother's side of the family. I'm lucky that my GP understands my levels of physical activity, and that she and her practice nurse monitor my health regularly. I also see my endocrinologist once or twice a year. With any luck I'll be able to stay off the blood pressure meds for a few more years yet!
