A blood pressure of 153 mmHg is considered to be Grade 1 hypertension if it remains at this level for three retests on a different day, which is relatively high. A blood pressure of 153 mmHg is relatively high. Normal people may experience an increase in blood pressure when they are emotionally aroused or do not have enough rest, but the blood pressure tends to return to normal after the triggers are removed. If the systolic blood pressure is ≥140mmHg or diastolic blood pressure is ≥90mmHg in three measurements taken at rest on non-simultaneous days, it is a sign of hypertension. In particular, if a systolic blood pressure of 140 to 159 mmHg and/or a diastolic blood pressure of 90 to 99 mmHg is met, it is classified as hypertension grade 1. Because long-term exposure to this level of blood pressure can increase the incidence of heart disease, cerebrovascular disease and other diseases, active intervention is needed. In normal times, pay attention to diet low in oil and salt, quit smoking, keep appropriate physical exercise and sufficient rest, avoid emotional excitement; if necessary, medication should be administered under the guidance of a doctor. You can choose to take angiotensin-converting enzyme inhibitors such as captopril, calcium channel antagonists nifedipine, diuretics hydrochlorothiazide and so on. It is recommended to consult a doctor as soon as possible to standardize the diagnosis and treatment.
