The current high pressure of 180 mmHg, but no dizziness, may be physiological elevation of blood pressure, or may be the individual reaction is not sensitive. 1. Physiological elevation of blood pressure: For example, blood pressure will rise reflexively when the exercise is just finished or when the emotion is agitated, but after the emotion is calmed down or after resting, the blood pressure can be returned to normal, which is mostly a transient elevation, and the blood pressure does not increase on the weekday of the remeasurement. 2. Individual insensitivity: Some hypertensive patients are insensitive to blood pressure increase, or have no symptoms when their blood pressure increases for a long period of time but the patient has already tolerated it. The current diagnostic criteria for hypertension are three or more measurements on different days, at rest, showing a systolic blood pressure greater than or equal to 140 mm Hg and or a diastolic blood pressure greater than or equal to 90 mm Hg, i.e. hypertension. If you have a high blood pressure of 180 mmHg, you should go to the cardiovascular department of the hospital as soon as possible to see if you are hypertensive. Those who are diagnosed with hypertension, even if asymptomatic, should be actively treated under the guidance of a doctor.
