Whether or not a low blood pressure of about 60mmHg is dangerous depends on the patient’s underlying blood pressure value, as well as the comorbid underlying diseases, clinical symptoms, and so on. Low blood pressure is diastolic blood pressure, normal people’s diastolic blood pressure fluctuation range should be between 60 ~ 90mmHg, if the blood pressure is usually on the low side, diastolic blood pressure is around 60mmHg, and there is no symptoms such as dizziness, panic, cold sweat and so on, there is no danger in general. However, if an elderly patient has underlying diseases, especially cardiovascular diseases, it is best to control the diastolic blood pressure above 60mmHg. If the diastolic blood pressure is too low, there is a certain risk, which may easily lead to insufficient cerebral arterial blood supply, insufficient myocardial blood supply, and dizziness, nausea, and pre-cardiac discomfort and other symptoms. If the diastolic blood pressure was high in the past and suddenly dropped to about 60mmHg, and the patient has the symptoms of dizziness, head sinking, weakness, and the risk of fainting, it is recommended to consult a doctor in time, to avoid delaying the time of treatment.
