People with high blood pressure, have you ever thought that one day, without medication, your blood pressure will drop on its own initiative? Today's experiment will tell you the answer:
We found three hypertensive patients of different ages and different course of disease to measure their blood pressure first, and then after entering the mysterious room for an hour, we found that the blood pressure of the three audience members had decreased to varying degrees. For more information, please pay attention to this episode.
It turns out that this kind of active decline in high blood pressure is an illusion, and there are two major dangers for patients.
1. Hypoxia caused by short-term blood pressure reduction
In the treatment guidelines for hypertension, whether at home or abroad, there are requirements for the magnitude and time of blood pressure reduction, and it is required that blood pressure be lowered to normal in 1-3 months. Now it goes down in about an hour, and if the pressure drops by more than 30%, shock will occur in severe cases.
2. Blood pressure fluctuates greatly
This kind of blood pressure is lowered, if there is no correct intervention after two hours, he will go up again, the original high blood pressure is most afraid of blood pressure fluctuations, if not even if it is found, in fact, such a situation, at least many times a day, blood pressure up and down is like a "roller coaster", it is very dangerous - sharp fluctuations in blood pressure can significantly increase the risk of cardiovascular events. For the elderly, the blood vessels are already very brittle, which is equivalent to this broken elastic band. The more you pull, the greater the breakage, and these places are also prone to blood clots.
What causes postprandial hypotension?
1. Age over 65 years old: Regardless of whether they are healthy or not, the elderly are prone to postprandial hypotension. Aging leads to decreased vascular elasticity, impaired vascular endothelial function, decreased cardiac function, sympathetic nerve damage, decreased baroreceptor sensitivity, and weakened ability to regulate blood pressure, so it is easy to lead to postprandial hypotension in the elderly.
2. Long-term hypertension: the incidence of postprandial hypotension in elderly hypertensive patients is significantly increased, especially for those patients with unstable preprandial basal blood pressure, or patients with high preprandial blood pressure, the higher the incidence of postprandial hypotension, the greater the decline. Because long-term hypertension promotes atherosclerosis in the arteries of the whole body, it can cause a decrease in the sensitivity of the baroreceptors of the aortic arch and carotid sinus, and cannot quickly and effectively regulate the drop in postprandial blood pressure.
In addition, it is related to a special type of food, what is it? This episode will explain it in detail.
