It is not good to flush the blood vessels in the elderly. The treatment of flushing the blood vessels is that some doctors and older people hope to use medicines to expand the blood vessels and improve the circulation at the time of the change of seasons, so that the state of the blood vessels can be changed and the blood vessels will not be clogged. However, this kind of treatment is not effective according to the evidence-based theory of modern medicine, and many studies have proved that it is not effective, and in the process of flushing the blood vessels, because of the large amount of fluid input, some older people will experience cardiac failure leading to pulmonary edema, etc. Moreover, the side effects of the drugs when they appear in many older people often bring about the depletion of the liver function, renal function and other organs, and the most dangerous thing is that it may occur The most dangerous thing is that there may be allergic reactions, resulting in an increased risk of sudden death, so the treatment of blood vessel flushing for the elderly does not pay off.
