Hypertension: High Blood Pressure – The Facts
In their majority hypertension sufferers are troubled with a kind of raised blood pressure called essential hypertension. There are numerous, but rarely clear, underlying causes for that. Maintenance of a normal blood pressure is a key factor to many diseases prevention throughout life. Hypertension or high blood pressure is a health condition that needs to be contained to prevent many of these health problems including: disease of the kidneys and heart conditions, heart muscle thickening, strokes, poor circulation of extremities, visual system problems and fall of brain function.
High blood pressure generally increases as a person ages and such abnormal increases can related to numerous causes.
Atherosclerosis: this is a coronary arterial disease; arteries become less elastic and can not dilate due to the development of plaque. When blood vessels turn inflexible then blood pressure stays high. If the plaque build up goes on it will compromise over time the supply of blood to kidneys and reduce their ability to check blood volume and therefore control blood pressure.
Obesity: a great deal of obesity is linked with high blood pressure particularly with females. Overweight individuals run a sixfold risk of suffering abnormal high blood pressure compared to that of lean individuals. Obesity is believed to be the number one element that is associated with hypertension since increase in body mass increases the demand for increased blood circulation. The additional blood vessels required increase the work output of the heart and consequently the blood pressure.
Inactivity: it is believed this to be the number two contributing factor to hypertension - vlose related to an individuals life-style. Engaging in frequent physical activity of 30 minutes each time and lose as little as five to seven kg, could most frequently bring hypertension and health dangers down to controllable levels. With higher blood pressure comes bigger and higher risk.
Elevated levels of insulin: raised insulin is connected with insulin resistive adipose cells (fat cells). retention of sodium (Na) in the body is increased with Insulin and this in turn could speeds up coronary artery disease. It is believed that more than 60% of individuals suffering from diabetes also have high blood pressure.
Additional factors that lend to hypertension include: excess of sodium intake in the diet; the exact mechanics are not clear however, it is clear that sodium retention step-ups retention of fluid which increases the volume of fluid. This in turn will require increased blood pressure for the elimination of excess sodium. - Alcohol consumption excessiveness; contributes more than 10% of all the cases and concentrations of lead in bones; has shown also to increase hypertension risk.
Hypertension can be detrimental to several body organs and systems and he risk factors are numerous. However, risks can be highly reduced with suitable life-style changes. Studies have establish that a diet low in sodium and plentiful in calcium magnesium and potassium, can decrease high blood pressure in a very sort time period.
Expert opinion proposes that individuals with borderline or mild hypertension attempt to lower their blood pressure by life style changes and dieting before resort to drug treatment for high blood pressure . Taking medication over long periods of time turns out to be expensive and holds many side effects. However, those diagnosed with hypertension may need to begin treatment as the condition often advances and with time can become serious and become drug resistant .
Medicinal drugs that generally prescribed for the control of hypertension include beta-blockers, diuretics, angiotensin enzyme inhibitors and calcium blockers. Most of the time a combination of drugs is used. These drugs work on slowing down the rate of the heart and induce vasodilation.
