After the cause of the rectal bleeding is diagnosed, the condition is treatable. An endoscopy is used not only to diagnose rectal bleeding but also used to treat rectal bleeding. Through the endoscope:
- Chemicals can be injected directly into the site to stop the bleeding
- The bleeding area can be treated with heat, or cauterized, to stop the bleeding
- A clip can be placed on a bleeding blood vessel
When rectal bleeding is severe or recurrent, surgery may be needed to correct the bleeding. After rectal bleeding is controlled, medications can be prescribed to prevent further bleeding.
