Low blood pressure refers to diastolic blood pressure. High blood pressure should be measured several times while remaining quiet, except in cases of transient elevation. Usually, both systolic and diastolic blood pressure rise simultaneously in humans, with some systolic blood pressure rising predominantly in the elderly, while diastolic blood pressure often rises in young people. If the patient’s blood pressure is elevated, it can be considered related to genetics, bad habits, other diseases and other reasons. 1, genetic factors: high low pressure can be caused by genetic factors. Hypertension has a hereditary tendency, and if there are hypertensive patients in the immediate family of three generations, the probability of the offspring suffering from hypertension will also increase significantly. 2. Bad lifestyle habits: Low pressure elevation caused by bad lifestyle is the most common, such as high salt diet leading to water and sodium retention in the body, which induces blood pressure elevation. Frequent late nights, poor sleep quality, as well as work stress, tension and anxiety can induce abnormal neuroendocrine activation in patients, thus inducing elevated low pressure; 3, other disease factors: the resistance of human arterial blood will increase when low pressure is high, commonly due to peripheral small vessel lesions or spasm, increased blood viscosity, etc. For the treatment of elevated low pressure, it should be built on the basis of improving poor lifestyle. Proper mood control, active exercise, removal of various undesirable triggers, improved sleep, as well as weight control, etc., can help control blood pressure. If the low pressure is still high after improving the lifestyle, you should seek medical attention and use medication according to the cause under the guidance of a doctor.
