Causes of high blood pressure and ways to lower it? I am 30 and recently my blood pressure was 140/90.? I dont smoke, I dont drink excessively... I excerise 30-45 mins 4 to 5 days a week. I am on wieght watchers so trying to lose wieght, I just wasnt sure if it is only the wieght being an issue. Stress is definatley to the max! My dr didnt seem to concerned, just said we will keep an eye on it.
