Hemorrhoids are normal vascular structures in the anal canal that can become symptomatic due to straining, prolonged sitting, or pregnancy. Common symptoms include painless rectal bleeding, prolapse or bulging of tissue from the anus, itching, and pain from thrombosed external hemorrhoids. Hemorrhoids are classified based on location above or below the dentate line and degree of prolapse. Diagnosis is made through history of symptoms and physical exam finding hemorrhoidal tissue.
