The normal values of systolic blood pressure are usually 90-139 mmHg and diastolic blood pressure 60-89 mmHg for a middle-aged man of 46 years old. There are many factors affecting blood pressure, such as heredity, age, diet, weight, emotions, alcohol consumption, and changes in the weather, which may lead to fluctuations in blood pressure. For example, irregular work and rest and heavy drinking may lead to higher blood pressure. The incidence of hypertension may increase significantly with age. At 46 years of age, you are middle-aged. When you take blood pressure measurements, no special treatment is usually needed as long as your blood pressure is within the normal range. If the blood pressure is outside the normal range, it is recommended to avoid alcohol, overwork, and emotional fluctuations. If the blood pressure measurement is performed several times and ≥ 140/90 mmHg, it is considered to be related to hypertension. It is recommended to pay attention to lifestyle intervention, low-salt and low-fat diet, increase exercise, weight control, close follow-up, and medication under doctor’s guidance if necessary.
