Measuring blood pressure is the only way to know whether your blood pressure is high or low. Blood Pressure rises and falls with each beat of your heart, that’s why blood pressure measures with two numbers. The systolic and Diastolic blood pressure. The top number refers to the amount of pressure in your arteries during contraction of your heart muscles. This is called systolic blood pressure. The bottom number refers to your blood pressure when your heart muscles rest in between beats. This is called diastolic blood pressure.

Systolic Blood Pressure:- when your heart beats, it contracts and pushes blood through the arteries to the rest of your body.The force creates pressure on the arteries. This is called systolic blood pressure. A normal systolic blood pressure is 120 or  below. A systolic blood pressure of 120-139 means you have normal blood pressure that is higher than ideal. Even people with this level are at a greater risk of developing heart diseases. A systolic blood pressure of 140 or higher, on repeated measurements is considered to be hypertension. Systolic blood pressure can be caused by artery stiffness, heart valve problem or diabetes.

Diastolic Blood Pressure:- The diastolic blood pressure indicates the bottom number which indicates the pressure in the arteries when heart rest in between beats. A normal diastolic blood pressure number is 80 or less. A diastolic blood pressure between 80 and 89 is normal but higher than ideal. A diastolic blood pressure 90 or higher on repeated measurements, is considered to be hypertension. High diastolic blood pressure can be caused by diabetes, kidney diseases, obesity,smoking,hardening of arteries or history of heart diseases.
It is important to check your blood pressure frequently and ensure your blood pressure is normal to decreases the risk of heart attack, heart stroke and organ failure. Moderate diet , moderate exercise, quit smoking are keys to normal blood pressure.
