Systolic blood pressure vs diastolic blood pressure

Every time your heart beats (pumps blood) the pressure in your arteries increases. Your highest blood pressure is called systolic blood pressure. In between heart beats when the heart is resting the blood pressure decreases and the lowest blood pressure is called diastolic blood pressure. Blood pressure reading is written or denoted with systolic pressure on top and diastolic pressure on the bottom like 120/80 or 130/90.

Low blood pressure and heart health

If you are healthy and the low blood pressure does not cause any problems it is a sign of good cardiovascular (heart and blood vessel) health. But if your low blood pressure is associated with symptoms, it can be a sign of an underlying problem

If your blood pressure remains constantly low and does not cause any problems it is almost never serious. But if the blood pressure drops suddenly it is associated with symptoms of dizziness or lightheadedness due to the decreased blood supply to the brain. Your risk of developing both low and high blood pressure increases with age.
