A high pressure of 153 mmHg and a low pressure of 113 mmHg, if measured correctly, falls into the category of grade 3 hypertension, which is relatively serious, and if it is only measured once in a while, it is not indicative of a problem and requires further examination. Adults without antihypertensive drugs are considered hypertensive when blood pressure is measured three times on non-same days in the patient’s quiet state if the high pressure is ≥140 mmHg and/or the low pressure is ≥90 mmHg. Hypertension is also categorized as Grade 1, Grade 2, or Grade 3 according to the level of blood pressure. Grade 1 hypertension (mild) has a high pressure between 140-159 mmHg and/or a low pressure between 90-99 mmHg; Grade 2 hypertension (moderate) with high pressure between 160 and 179 mmHg and/or low pressure between 100 and 109 mmHg; Grade 3 hypertension (severe) high pressure ≥180 mmHg and/or low pressure ≥110 mmHg; Therefore, if a high pressure of 153 mmHg and a low pressure of 113 mmHg is the result of a correct measurement, it can be considered grade 3 hypertension, which is a very serious elevation of blood pressure and requires immediate medical attention and antihypertensive treatment as prescribed by the doctor. If the blood pressure is only measured once in a while, it is recommended to seek medical attention to measure it again, observe the blood pressure situation, and decide whether treatment is needed based on the results of the re-measurement.
