Hypertension 153mmHg is considered high. A person’s blood pressure is divided into two parts: systolic and diastolic, where systolic blood pressure greater than or equal to 140mmHg and/or diastolic blood pressure greater than or equal to 90mmHg is considered high blood pressure. A blood pressure of 153 mmHg, both systolic and diastolic, exceeds the normal range of blood pressure and is considered hypertension. However, just an occasional measurement with a blood pressure value greater than normal is not sufficient to diagnose hypertension. It is recommended that multiple measurements not taken on the same day be taken, and if they are all greater than or equal to the normal blood pressure value, then hypertension can be diagnosed. Hypertension is further categorized into primary hypertension and secondary hypertension according to its cause. Primary hypertension, such as hypertension caused by vascular sclerosis in elderly patients. Secondary hypertension, such as hypertension due to acute glomerulonephritis. Prolonged hypertension has the possibility of secondary intracranial hemorrhage, and requires prompt medical attention and standardized treatment under the guidance of a doctor.
