High pressure 100 low pressure 65, usually refers to systolic blood pressure 100mmHg diastolic blood pressure 65mmHg, the above blood pressure is within the normal blood pressure range, but may need dynamic monitoring, but also need to be combined with their underlying blood pressure to determine the situation. The normal range of systolic blood pressure is 90~140mmHg, and the normal range of diastolic blood pressure is 60~90mmHg, so the measurement of blood pressure 100/65mmHg belongs to the normal range. However, it should be pointed out that blood pressure fluctuates, and a normal blood pressure does not completely mean that the blood pressure is within the normal range. Patients who have symptoms related to dizziness and headache may need dynamic monitoring. In addition, if the patient usually has a significant increase in blood pressure, measuring blood pressure 100/65mmHg in the case of pneumonia and other diseases may be a manifestation of a decrease in blood pressure, suggesting that the condition is serious. Therefore, a blood pressure measurement of 100/65 mmHg is generally considered normal, but it may be necessary to combine the patient’s baseline blood pressure as well as the patient’s specific condition to assess whether the blood pressure is normal. If abnormal blood pressure or discomfort is found, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
