We all know that the diagnostic standard of hypertension is 140 / 90 mmHg. When the high pressure is higher than 140 mmHg, many people will pay attention to it and think that it is already hypertension. However, many people find that the low pressure is increased, such as higher than 90 mm Hg, but they do not pay much attention to it, and think that the increase of low pressure is not harmful. In fact, the harm caused by the rise of low pressure is no less than that caused by high pressure rise. Let’s learn what low pressure is? Why does low pressure rise? How to raise the low pressure?
1. Low pressure: clinically, it is called diastolic blood pressure, which corresponds to systolic blood pressure. When we measure blood pressure, we will record two values, and the smaller one is called low pressure.
2. How to form low pressure: with the contraction and relaxation of the heart, the blood inside the artery will increase and decrease, and the blood vessel will also expand and retract. When the heart relaxes, the blood inside the artery will be reduced, and the arterial blood vessel will retract. At this time, the pressure inside the blood vessel is called diastolic pressure.
1. From the mechanism of increased diastolic blood pressure, the activation of sympathetic nervous system and the increase of renin angiotensin aldosterone system activity are the important reasons for the increase of diastolic blood pressure.
2. According to clinical observation, the increase of diastolic blood pressure is more common among young and middle-aged people, which may be related to their better vascular elasticity and vascular weakness. Diastolic blood pressure is often associated with obesity, metabolic abnormalities, work pressure, mental stress, poor sleep, lack of physical exercise, etc., which are easy to lead to sympathetic activation.
1. Non drug treatment: the increase of diastolic blood pressure is related to lifestyle to a large extent, so it is very necessary to carry out drug treatment for patients with increased blood pressure, such as low salt diet, weight loss, increased exercise, smoking cessation and alcohol restriction, mental stress relief, regular work and sleep improvement, which are helpful to the control of diastolic blood pressure.
2. Drug therapy: for patients who have undergone non drug treatment for a period of time, usually three months, and whose diastolic blood pressure is still not significantly decreased, drug treatment should be considered. As the patients with increased diastolic blood pressure, their sympathetic nerve activity and the activation of renin angiotensin aldosterone system are important characteristics, so for this type of patients, by the other receptor blockers, angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists will have a better effect.
in a word, increased diastolic blood pressure is more common among young people, and its occurrence is closely related to the activation of sympathetic nervous system and the increase of excitability of renin angiotensin aldosterone system. If necessary, beta blockers, angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists can be selected for treatment. BEAUTY&SKIN CARE
