The formation of hemorrhoids is not directly related to the usual washing of the anus, but is mainly caused by the impaired return of blood to the veins around the anus. In addition, prolonged standing or sitting, as well as a variety of reasons for increased negative pressure, including pregnancy, can create pressure around the anus, thus increasing the risk of hemorrhoid formation. Regular anal cleansing with saline or warm water can increase the rate of blood circulation around the anus and prevent hemorrhoid symptoms from appearing. Cleaning alone is not enough to prevent hemorrhoids, but you should pay more attention to increasing physical exercise to speed up the return of blood to the veins around the anus, and pay attention to improving your diet to prevent dry stools.
