The terms “blood pressure 115 and 75” are commonly used in medicine to refer to a blood pressure of 115 mmHg systolic and 75 mmHg diastolic, a measurement that falls within the normal range. Hypertension is defined as a condition in which the systolic blood pressure is ≥ 140 mmHg and/or the diastolic blood pressure is ≥ 90 mmHg in three measurements taken on a non-same day under standardized measurement conditions, while the blood pressure of 115/75 mmHg is below the standard, and therefore belongs to the normal blood pressure range. It should be pointed out that the blood pressure measurement cannot be used to determine whether the blood pressure is qualified or not, if hypertension is suspected, it may be necessary to take several measurements. If your blood pressure is 115/75mmHg, don’t worry, pay attention to your daily dietary habits, eat a low-salt, low-fat diet, stop smoking and limit alcohol consumption, and exercise moderately. If there are high risk factors for hypertension, you should pay attention to regular monitoring of blood pressure, if there is any abnormality, you should consult a doctor in time, and take medication as prescribed by the doctor for treatment.
