An occasional increase in blood pressure generally does not matter and is related to the state of the blood pressure at the time of measurement, such as exercise, mental stress, etc. If these factors are excluded and there is still occasional hypertension, the patient still has a tendency to be hypertensive. Patients may have a pre-hypertensive state, where the blood pressure is between 120/80 mmHg-140/90 mmHg, and patients need to pay attention to lifestyle interventions. If an increase in blood pressure occurs after exercise or after a meal, the patient’s blood pressure measurement status is incorrect, and a regular blood pressure measurement in a quiet state at the same time period is required for side-by-side comparison.
