You have hypertension and you may need medications to control your blood pressure, especially if you suffer from other chronic disease, like diabetes and kidney impaired function.
Hypertension leads to organ damage overtime, affecting heart, kidney, eye, arteries and blood supply to all parts of the body, and brain.
When blood pressure readings are high as yours, it is very possible that you'll start with medications as soon as possible.
Life style modifications are important, but, alone are helpful for lower blood pressure readings.

Best wishes!
