The normal value of systolic blood pressure in normal adults is around 90~140mmHg. If the systolic blood pressure is in the normal range of 90~100mmHg, if the systolic blood pressure is lower than 90mmHg, then it belongs to low blood pressure.
In case of hypotension, physiological hypotension often has no obvious symptoms and does not have much effect on the body; in case of pathologic hypotension, patients often have symptoms such as pale face, cold wet skin, dizziness, black haze, and body weakness. Due to insufficient blood supply to the brain, patients often show lethargy and drowsiness, and their work and study efficiency is affected, and at the same time, cardiovascular and cerebrovascular diseases are easily induced.
