Hemorrhoids

Hemorrhoids are soft venous clusters formed by the expansion and flexion of venous plexuses in the submucosal end of the rectum and subcutaneous skin of the anal canal. More common in standing and sedentary. Hemorrhoids include internal hemorrhoids, external hemorrhoids, and mixed hemorrhoids. It is a chronic disease of one or more soft venous clusters formed by varicose veins in the anal rectum and anal mucosa. Usually when the bowel movement is continued, the vein pressure will increase and the vein will swell. During pregnancy, hemorrhoids often occur due to the compression of the pelvic veins, which hinders blood circulation, and many obese people also suffer from hemorrhoids. If you have hemorrhoids, the walls of the veins that are enlarged and twisted in the anus can become very thin, so they can easily break during defecation. Internal hemorrhoids are hemorrhoids that grow at the beginning of the anal canal. If the swollen vein is located lower, almost at the mouth of the anal canal, this varicose vein is called external hemorrhoid. External hemorrhoids sometimes prolapse or emerge outside the anal canal. But this happens only during defecation, and it will retract to its original position after defecation. Thrombosis can occur in both internal and external hemorrhoids. When a thrombus occurs, the blood in the hemorrhoids clots and causes pain.
