Many factors can cause your blood pressure to rise, and each factor may or may not require medication. Many people make lifestyle changes that lower their blood pressure without medication; especially for pre-hypertension and stage 1 of hypertension. Also, each time you take your blood pressure, make sure you are still and calm, sitting with both feet on the floor, arm supported on a flat surface, and you are measuring at the same time everyday. You can also take multiple readings in one sitting, but wait one minute between each reading. These steps will ensure you are providing your healthcare provider with the most accurate blood pressure reading!
