The lateral pressure on the vessel walls caused by blood flowing through the vessels is called blood pressure, which is categorized into systolic and diastolic according to the different systolic and diastolic states of the heart. In general, the normal range of blood pressure is 90~139mmHg/60~89mmHg, the former is systolic pressure and the latter is diastolic pressure.
Systolic blood pressure 92mmHg, diastolic blood pressure 66mmHg are in the normal blood pressure value range, if this blood pressure for quiet, awake state measurement of blood pressure 92/66 is normal.
Some factors such as strenuous exercise, nervousness, emotional excitement may cause a physiological increase in blood pressure, if these factors affect the measured blood pressure, it is considered that the blood pressure is low within the normal range, and it is recommended to measure it again in a sober and quiet state.
If the value of blood pressure measured again is 90~139mmHg/60~89mmHg, then the blood pressure is normal; if it is lower than the above normal range, then it may be low blood pressure, and the causes of low blood pressure may be malnutrition, hypothyroidism, etc. It is recommended to go to a regular hospital as soon as possible for consultation and relevant examinations to clarify whether there is any abnormalities in blood pressure.
