Low blood pressure is medically called diastolic blood pressure, diastolic blood pressure of 93mmHg is not normal, indicating that the blood pressure is high, the normal range of diastolic blood pressure should be <80mmHg. The cause of elevated diastolic blood pressure may be physiological factors, or it may be hypertension. 1. Physiological factors: If the patient has undergone strenuous exercise or has experienced abnormal mood swings due to certain events before measuring the blood pressure, it may lead to an increase in diastolic blood pressure. The patient can sit still for some time and measure again to see if the blood pressure will return to normal. 2. Hypertension: If the patient's diastolic blood pressure is ≥90mmHg or systolic blood pressure is ≥140mmHg on three measurements taken on non-same day without taking antihypertensive medication, he/she may be suffering from hypertension. It is necessary to go to the hospital for consultation. After the diagnosis is confirmed by the doctor, it is necessary to follow the doctor's instructions to regulate the lifestyle, and if the blood pressure is still poorly controlled or there are clinical symptoms such as headache, dizziness, etc. it is recommended that antihypertensive medication be taken to avoid other complications due to prolonged high blood pressure. If the measurement of blood pressure is abnormal, it is recommended to consult a doctor as soon as possible to avoid delaying the condition.
