“What should I do if my blood pressure is high?”

Check it every morning for 1 week. Keep a log book of your BP readings and bring it to your doctor.

Is this new occurrence for you?

The approach to elevated BP is first to document it is not episodic or stress related (so called "white coat hypertension") and assessing for comorbid medical problems (Diabetes and chronic renal insufficiency). If BP is persistently elevated and mild (Systolic (top number) above 140 mm Hg or diastolic (lower number) above 85 mm Hg) salt and alcohol intake restriction and weight reduction may be a first step. If moderately elevated (Systolic above 160 mm Hg, diastolic above 100 mm Hg) and higher risk mitigating factors, BP meds may be started. Since your kidney function and blood sugar would also need to be assessed would recommend seeing an internist or family doctor to discuss your individual situation.
