The normal values for blood pressure are 90 to 139 mmHg systolic and 60 to 89 mmHg diastolic. low blood pressure in the elderly can be caused by physiological factors, but it can also be caused by malnutrition, aortic stenosis and other factors.
Blood pressure is the lateral pressure exerted by blood against the walls of blood vessels and the driving force for blood flow. It can be divided into systolic and diastolic blood pressure, with normal values of 90 to 139 mmHg and 60 to 89 mmHg. Some thin elderly people, whose blood pressure will be slightly lower, may have physiological low blood pressure, whose blood pressure is lower than normal for a long period of time, but without any other discomfort.
Hypotension in the elderly may also be caused by malnutrition, aortic stenosis and other pathologic factors, and may be accompanied by other symptoms such as fatigue, cough and chest tightness.
If the elderly have low blood pressure, they should go to the hospital in time, improve the relevant examination to clarify the cause of the disease, and treat the symptoms under the guidance of the doctor.
