This depends on where the 150 is on your blood pressure reading, and understanding what the numbers mean takes a basic understanding of a blood pressure readout. Blood pressure is the pressure the blood places on the walls of blood vessels, and it depends on a person’s heartbeat, blood, artery walls and overall health of the person. When you take your blood pressure, the results are systolic and diastolic numbers.
The top number is systolic blood pressure, meaning the pressure caused by the contraction of the heart as it works to pump blood into the arteries. The bottom number is diastolic blood pressure, and is the expansion of the chambers of the heart with every heartbeat.
The generally accepted normal number is 120/80. If your top number is 150, you fall into the Stage 1 Hypertension category and should probably work to adopt a healthier lifestyle to get your numbers down to normal. A systolic number from 120 to 139 is considered pre-hypertension, and 160 or higher is Stage 2 Hypertension. A bottom number over 100, especially at 150, is a cause for immediate concern. If this is the case, see a doctor or go to the emergency room for treatment immediately.
