A diagnosis can generally be confirmed by examining either the whole colon or the rectum using an instrument (endoscope). When necessary, this procedure (the endoscopy) can be performed under sedation, making the procedure pain free. When a haemorrhoid diagnosis is confirmed, the milder problems can be treated locally with ointment.
If the ointment does not help locally, a large proportion of haemorrhoids can be resolved by placing a rubber band around the haemorrhoid. The haemorrhoid tissue withers away and falls off within a week of the procedure. This procedure can be repeated if necessary.
Haemorrhoids have to be operated on if they bleed profusely or are located outside of the rectum. During the operation, the haemorrhoid tissue is removed, the wound is allowed to heal by itself.
