A low blood pressure of 52 mmHg is not normal, and this is when the blood pressure level belongs to a reduced state. Low pressure is also known as diastolic pressure, and diastolic pressure is generated by the lateral pressure on the arterial blood vessel wall when the elasticity of the large arterial vessels retracts after the heart contracts, pushing the blood to continue to flow forward. Reduced diastolic blood pressure is most commonly seen in the elderly with hypertension, due to the presence of atherosclerosis in the elderly, while hypertension also aggravates the degree of atherosclerosis. As a result of atherosclerosis, the walls of the blood vessels become stiff and less elastic, which causes a decrease in diastolic pressure, i.e. low pressure, which can also be seen in healthy young women. In this case, the patient can have no symptoms of discomfort such as dizziness and no signs of target organ damage, and it is a physiological hypotension, which does not require special treatment, although the low pressure is low.
