I just checked my blood pressure on the machine at the local pharmacy. it was 154/101. i don't have a history of high blood pressure. what should i do?

High blood pressure: Is defined as two or more blood pressure readings above 135/85 at two distinct time points. I would suggest having a manual BP measured at two different time points. Secondary reasons for elevated BP are stress, excess salt intake, caffeine and alcohol. Also diet and exercise and cutting caffeine, salt and alcholol can help. Assess for sleep apnea as well.
