Hemorrhoids are a relatively common condition that can occur as a result of sedentary behavior. This is because hemorrhoids are enlargements of the subcutaneous venous plexus under the mucous membrane at the end of the rectum and around the anal canal. The fact that the rectal vein and its branches are lacking of venous valves, and the fact that the blood does not flow back easily due to the influence of gravity when sitting for a long time, can cause the hemorrhoidal vein to swell and become convoluted, thus producing hemorrhoids. After getting hemorrhoids, you should avoid squatting and sitting for a long time, it is possible to make the bowel discharge poor, the rectum is easily compressed by the fecal mass, thus affecting the blood return, the feces is not easy to empty the lower rectum and the anal canal produces a relatively large pressure, so that the blood vessels are compressed, the anorectal venous reflux obstruction thus producing hemorrhoids.
