hai,
As per your quote your systolic blood pressure(164) is high. it seems to be
isolated systolic hypertension.
Diastolic pressure(84) is normal.
normal systolic blood pressure -100 to 140mmHg.
diastolic pressure- 60 to 90mmHg.
systolic hypertension didn't need any medication.
control in diet and exercise will help you in bring back to normal blood pressure.
Limit the amount of sodium (salt) you eat. Aim for less than 1,500 mg per day.
Eat a heart-healthy diet. Include potassium and fiber, and drink plenty of water. Stay at a healthy body weight.
Exercise regularly -- at least 30 minutes a day .
follow this advise for one month and take your blood pressure and consult a general physician if blood pressure remain the same.
thank you
hope i answered your query.
