It turns out that hemorrhoids are caused by sedentary, standing for a long time or overeating spicy food. In fact, sexual life can also cause hemorrhoids. Don't believe it, because according to research, excessive sexual life, unclean sexual intercourse and forbearing ejaculation are all abnormal sexual lives, which will cause the onset of hemorrhoids, especially those who already have hemorrhoids. During sexual life, people's whole body muscles are in a state of high tension, especially the muscles of the back and buttocks are constantly contracting, which will cause varicose veins and congestion and form hemorrhoids. At the same time, twitch-like contraction occurs around anus during sexual intercourse, which causes strong twitch-like peristalsis in the lower segment of large intestine, leading to local temperature increase, followed by inflammation and swelling, which hinders the normal circulation of hemorrhoid vein blood. According to clinical observation, frequent sexual intercourse is not only easy to cause hemorrhoids, but also can induce acute attack of hemorrhoids. Men, in particular, are more likely to occur or be attacked. This is because frequent sexual intercourse will make genital nerve receptors highly excited for a long time, local blood circulation disorder, blood vessels will suddenly contract and spasm, and suddenly relax. In this way, the blood flow will be delayed and slow, resulting in the local blood flow being in an unobstructed state, the blood circulation around the anus and rectum will be hindered, and local blood vessels are prone to varicose veins and congestion. Coupled with the impulse, breath holding and pressure during sexual intercourse, it is more likely to lead to various abnormal changes in local blood circulation, resulting in swelling and pain of anorectal mucosa and hemorrhoids. If the original hemorrhoids have frequent sexual intercourse, it will easily lead to the development of hemorrhoids, and even cause serious complications such as anal fissure, anal fistula and perianal abscess. Therefore, couples should be temperate in their sexual life, especially those with hemorrhoids, and should not have frequent sexual intercourse, let alone aggravate hemorrhoids and increase their own pain for temporary pleasure. Unclean sexual intercourse can also indirectly contribute to hemorrhoids. Both male semen and female vaginal secretions can flow to the anus. If you don't pay attention to cleaning, anal eczema may occur, causing local redness, hindering local blood circulation, forming blood stasis and inducing hemorrhoids. Forbearing sperm and not shooting is an act that violates the function of sexual life. Semen is not ejected during sexual intercourse, and gluteal muscles around anus are most affected, leading to spasmodic contraction. At this time, the pressure on the blood circulation around the anus is several times that of normal sexual intercourse, which is easy to cause hemorrhoids or aggravate the condition. Therefore, the reason why sexual life can also cause hemorrhoids is here. To prevent hemorrhoids, we should start from many aspects and pay more attention to it in order to reduce the incidence of hemorrhoids.
