Dear Dr. Mo: How to cope with high blood pressure, walking or resting?
Dear reader: First of all, you have a high blood pressure or Hypertension, if you have a sustained elevation of resting systolic reading of at least 140 mm Hg (millimeters of mercury) or a diastolic reading of at least 90 mm Hg, or both.
The top number in your blood pressure reading is the systolic pressure. It reflects the amount of pressure in your arteries when your heart pumps – it is generated by the heart as a pump and the larger its output, the higher the systolic pressure.
The bottom number is the diastolic pressure. It is the measure of the pressure in the arterial tree in between heartbeats, when the heart is relaxing and it depends on the total peripheral resistance to the blood going out of the arteries into the veins and back to the heart.
High blood pressure is a common condition in which the force the blood exerts against your artery walls is high enough to eventually cause health problems, such as heart disease. Heart has to work harder and harder as blood pressure rises above normal limits and over time, this weakens the heart. It also injures the arteries, which then become susceptible to plaque formation and atherosclerosis in them. At times, high blood pressure may rupture the artery leading to bleeding and strokes.
Blood pressure measurement is one of the most important measurements for any doctor to take in order to determine your health status. Many people have elevated blood pressure, which increases as we age or develop certain health conditions. The trouble is, that if left unchecked, our bodies quickly adapt to elevated values as we go about our daily lives unaware of a serious health problem slowly evolving inside of us – until a big symptom occurs – a heart attack, a stroke, a kidney failure, eye sight problem or internal bleeding.Undiagnosed and untreated elevated blood pressure is among the biggest and most serious threats to our health, both short and long term.
