Doctors usually reserve surgical treatment for very large and painful hemorrhoids, according to WebMD. Changes to diet and bowel habits successfully treat most cases of hemorrhoids.
Doctors treat internal hemorrhoids using nonsurgical procedures that reduce the blood flow to the hemorrhoids until they resolve, explains WebMD. Scar tissue left in the place of hemorrhoids supports the anal tissue to prevent the formation of new hemorrhoids. Types of nonsurgical procedures include using a rubber band to constrict the blood supply to the hemorrhoids or using a laser, heat or electric current to form scar tissue. Doctors usually only use surgical procedures for very large hemorrhoids or several small hemorrhoids. They also resort to surgery if other procedures do not work.
