You can lower your blood pressure within a few weeks by changing your lifestyle a bit. This is the advice from the Blood Pressure Association:-

My blood pressure has always been around 130/80, but at the last GP visit it was 130/88 and I started worrying. My mum had high bp and died from a heart attack at 66. I am 3 stone overweight, but have lost a stone at Weight Watchers and have tried to cut back on processed foods. Had my HRT check-up today - bp was 110/60, so I am pretty happy to have got it down in less than 6 months. I still have a long way to go with the weight, but it is possible to lower your blood pressure through diet fairly quickly. I never eat salt now, not on chips, no crisps etc. No caffeine either. I eat bananas too which are good for bp.
If your doctor was worried they would soon put you on bp tablets for a while, but really with a bit of healthy eating (and exercise if poss) you can soon sort this out. Don't worry, good luck.
