High BP. I went to my Diabetic Clinic today and my BP, Systolic, was somewhere in the 170s.?

Usually treatment is not started on just one high reading as it could be due to anxiety etc. but two weeks is also a long time to check it again. Get your BP checked from somewhere else and if still high go to your doctor. Meanwhile reduce salt intake, increase fibres and fruits in diet. exercise regularly. stop smoking reduce weight if applicable.
