The type of doctor that treats hemorrhoids is a colorectal surgeon, according to Remedy's Health Communities. Colorectal surgeons treat a number of conditions related to the lower digestive tract, including those affecting the anus, rectum and colon.
Hemorrhoids can be treated in a number of ways by the colorectal surgeon, depending on the severity. The several office-based treatments include rubber band ligation, cauterization and sclerotherapy, in which an agent is injected into the hemorrhoid to collapse and shrink it. For cases that are more severe or where simpler methods fail, a number of surgical options are available, including excisional hemorrhoidectomy, transanal hemorrhoidal dearterialization and hemorrhoidectomy, or hemorrhoidopexy.
