High blood pressure 160mmHg, low pressure 90mmHg is more serious, but do not be too nervous, active control can still have a better prognosis. Generally speaking, the normal value of blood pressure is that the high pressure is less than 140mmHg and the low pressure is less than 90mmHg. When the high pressure reaches 160mmHg and the low pressure reaches 90mmHg, and at the same time three measurements in the resting state in the non-same day reach this level, then it will meet the diagnostic criteria of grade 2 hypertension. Generally speaking, this level of hypertension is relatively less dangerous in the short term, but if it remains uncontrolled for a long period of time, it is more harmful to the human body, and may lead to complications such as heart enlargement, cerebral hemorrhage, renal insufficiency, and arteriosclerosis of the fundus of the eye. Therefore, it is recommended to consult a doctor and receive standardized treatment to keep blood pressure at an appropriate level.
