Blood in our body always moves in the circular motion. Blood filled with oxygen goes from the heart to all other parts of the body and blood vessels that have such function are called arteries. Blood pumps the blood from the heart to the organs and tissues in the body, and when it gets filled with carbon dioxide (or de-oxygenated, freed from oxygen it carried) veins distribute that blood to the lungs, to fill it again with fresh oxygen.
Blood pressure is the pressure in the arteries, measured when the heart pumps the blood out.
There are systolic and diastolic blood pressures. Systolic pressure is the pressure of the blood pumped out from the heart, while diastolic is the pressure experienced in the arteries when the heart is as rest (between the heartbeats). Systolic blood pressure is always the upper number shown on the screen when measuring the blood pressure and diastolic is the lower number.
Age affects the blood pressure significantly, as well as the gender, height, weight and the surrounding. Genetic predisposition and some medical conditions, like diabetes, could also affect your blood pressure. In most cases blood pressure is higher than it normally should be. Stress, cigarettes and alcohol are factors that increase the possibility of developing hypertension at some point of the life. Healthy lifestyle, which includes healthy eating habits and regular physical activity can benefit your blood pressure and maintain it normal.
Consult your doctor about your blood pressure. If necessary he/she will prescribe you some medications in order to keep your blood pressure normal and avoid potential medical consequences of hypertension.
Hyper and Hypo-tension
Blood pressure is measured in mmHg, and the value of 120/80 mmHg is considered normal. All measured values below that pressure are considered as low blood pressure (hypotension) and values higher than 120/80 are known as high blood pressure (hypertension).
Precisely, systolic blood pressure of about 50-90 and diastolic of 35 to 60mmHg is known as low blood pressure or hypotension. Numbers from 90 to 100 (systolic) and 60 to 70mmHg (diastolic pressure) are also called low normal blood pressure.
As perfectly normal blood pressure, doctors consider 100 to 130mmHg for systolic pressure and 70 to 85 for diastolic blood pressure.
If you happen to measure over 140 (to 160) mmHg systolic and 90 to 110mmHg diastolic blood pressure, you are suffering from high blood pressure. However, only people with measured values over 160 to 230mmHg of systolic blood pressure and 110 to 135mmHg diastolic pressure are considered as hypertension patients.
