Introduction
An evening blood pressure reading of 140/80 mmHg may indicate prehypertension or early-stage hypertension, which warrants attention. Normal blood pressure is defined as systolic pressure less than 120 mmHg and diastolic pressure less than 80 mmHg. Patients can adopt measures such as lifestyle modifications, regular blood pressure monitoring, and medication when necessary to help control blood pressure and reduce the risk of complications.
In general, a nighttime blood pressure reading of 140/80 mmHg may indicate prehypertension or early-stage hypertension and is usually considered abnormal, thus requiring attention. The detailed analysis is as follows:
Normal blood pressure is defined as systolic pressure below 120 mmHg and diastolic pressure below 80 mmHg. Hypertension is diagnosed when systolic pressure is 140 mmHg or higher, or diastolic pressure is 90 mmHg or higher. Prehypertension refers to systolic pressure between 120–139 mmHg and diastolic pressure between 80–89 mmHg. Therefore, although a nighttime blood pressure of 140/80 mmHg does not meet the diagnostic criteria for hypertension, it approaches the prehypertension range and is considered abnormal. Individuals with such readings are advised to modify their lifestyle, maintain a healthy diet, and develop good daily habits. If lifestyle changes fail to effectively control blood pressure, medication may be necessary, such as mannitol or metoprolol tartrate tablets, which should only be used under a doctor's supervision.
If any discomfort occurs, prompt medical consultation is recommended to avoid delaying treatment.
