Blood pressure of 148/89 mmHg is not normal and is classified as Grade 1 hypertension, high blood pressure. Blood pressure mainly describes the lateral pressure of blood on the wall of the blood vessel per unit area during the pumping process of the heart, and the commonly said blood pressure generally refers to the arterial pressure in the body circulation. The usual measurement of blood pressure is cuff measurement, i.e., upper arm cuff pressure, and the results include systolic blood pressure and diastolic blood pressure, which are also often referred to as high and low pressure. The normal blood pressure range for a normal adult requires a high pressure of less than 120 mmHg, along with a low pressure of less than 80 mmHg. A high value blood pressure in a normal adult is generally defined as a high pressure of between 120 and 139 mmHg, with or without a low pressure of between 80 and 89 mmHg. The diagnostic criteria for hypertension are high pressure greater than or equal to 140mmHg with or without low pressure greater than or equal to 90mmHg. Simply from the blood pressure value, the blood pressure of 148/89mmHg has reached the level of grade 1 hypertension. However, blood pressure can be affected by body activities, emotions, etc. Generally speaking, when measuring blood pressure, it is required to rest quietly for at least 10 minutes, and keep your emotions stable, so that the measurement value will be more accurate. Don’t worry if your blood pressure is high in a single measurement, it is recommended that you take multiple measurements, with an interval of more than 24 hours between measurement cycles, and measurements in strict accordance with the measurement specifications, so that the results will be more meaningful, and it is recommended that you seek medical attention, and under the guidance of a professional doctor, you can carry out the measurement of your blood pressure and its treatment.
