I`m 32 female, normal weight. having problem with high blood pressure 120/90, heart rate 118. i lasts for 3 months almost. what can be cause?

Need tests.: See your doctor for a careful history and physical exam, blood and urine tests, and an ekg. The high heart rate needs assessment; one must check thyroid function and search for other, less common, causes of a high heart rate. In addition, monitor your blood pressure sitting and standing, once or twice daily, and review the data with your doctor.

Hyperthyroidism?: The rapid heart rate is suspicious for an over active thyroid. Please see a doctor.

Many factors: 120/90 is only borderline elevated. Try to have more readings taken under different circumstances. Cut out salt and soda from you diet. Try to limit sodium to less than 1500 mg daily. Cut out any over the counter cold, allergy or NSAID medication like; motrin, advill, alleve. If you have done those things and your average readings are 140/90 or higher you should go to a doctor to be evaluated.
