Hello, the top number 112 is good, the bottom number 90 is at the borderline for diastolic. Normally the top number and bottom number has a difference of 40 mm Hg, the difference of yours is 22 mm Hg, this means decreased blood vessel elasticity. At the borderline, it's okay not to take the BP meds right away, but a healthy diet and daily exercise will help you a lot. Cut half of your sodium intake, take plenty of fruits, vegetables, olive oil, nuts, fish, walk for 30-60 minutes a day 4-5 days a week. And try to measure your BP frequently, if not everyday.
