About This Condition
Hemorrhoids are enlarged raised veins in the anus or rectum.
Common hemorrhoids are often linked to both diarrhea and constipation.1 Although the belief that hemorrhoids are caused by constipation has been questioned by researchers,2 most doctors feel that many hemorrhoids are triggered by the straining that accompanies chronic constipation.3 Therefore, natural approaches to hemorrhoids sometimes focus on overcoming constipation.
Symptoms of hemorrhoids may include painful swelling or a lump in the anus that can bleed and become inflamed, often causing discomfort and itching. There may also be bright red blood on the toilet paper, the stool, or in the toilet bowl.
Surgical treatment may be recommended for hemorrhoids that become very enlarged, protrude from the anus (prolapse), bleed frequently, or contain blood clots (thrombosis). Common procedures include freezing the affected tissue (cryotherapy), injecting chemicals into the hemorrhoid to shrink it (sclerosing solutions), surgically removing the hemorrhoid (hemorrhoidectomy), or placing rubber bands around the hemorrhoid for removal (ligation).
