Blood pressure is divided into systolic and diastolic blood pressure, it is usually considered that the normal range of systolic blood pressure is 100-120mmHg, and the normal value of diastolic blood pressure should be less than 80mmHg. so blood pressure 110-140mmHg is not normal. Blood pressure is the pressure of blood on the walls of blood vessels after the heart pumps blood. 3 measurements of systolic blood pressure greater than 140mmHg and/or diastolic blood pressure greater than 90mmHg on a non-same day is known as hypertension, which is an important factor leading to cardio-cerebral and cerebrovascular disease and kidney disease, in addition to increasing the risk of stroke. Hypertension is associated with factors such as genetics and poor lifestyle habits, and certain organic diseases may also lead to elevated blood pressure. It should be noted that a single measurement of high blood pressure does not directly diagnose hypertension, do not take medication on their own, it is recommended that patients go to a specialized hospital as soon as possible, to clarify the cause of the disease, to prevent misunderstanding of the condition.
