The “silent murderer” – – high blood pressure is called in this way. I let I steal up it slowly calmly and die of heart trouble or a stroke overnight. It is high blood pressure. The blood pressure is the pressure that blood sent off gives from heart on the wall of the blood vessel (artery). Because the heart repeats the shrinkage and expansion and sends blood off, time when time when blood pressure became highest lowered by blood pressure (upper blood pressure to be generally called), expansion of the heart by the cardiac shrinkage most for the shrinkage period is called diastolic blood pressure (blood pressure). I am flexible, and the wall of the blood vessel is flexible, but the wall of the blood vessel thickens to be opposed to this when high pressure suffers from blood vessel for a long time. And flexibility and elasticity are lost, and the blood vessel is tense, and the part of the blood vessel becomes small among them. This “is arteriosclerosis”. Then the blood pressure falls into a vicious circle to rise more. Therefore a burden depends on heart sending blood off.高血圧
The 95% or more are unidentified, and the high blood pressure calls this “essential hypertension”. A hereditary factor and the neglect of health of lifestyles such as salt and an adipose surplus intake, lack of exercise, obesity, stress, smoking, the alcohol participate a lot. On the other hand, there is a clear cause for the high blood pressure to be found by inspection. It is the high blood pressure that kidney disease or a disease of the internal secretion (hormone) are related to. These are called “secondary high blood pressure” and are the high blood pressure that can let you heal by the treatment such as operations unlike essential hypertension.
