These include:<\/p><ul><li><strong>Haemorrhoids<\/strong><strong>, or piles, <\/strong>are a common cause of rectal bleeding. They are swollen veins within the anus. The causes of haemorrhoids include chronic constipation, straining during bowel movements, pregnancy, etc. Aside from being a common cause of rectal bleeding, haemorrhoids can also cause significant pain.<\/li><li><strong>Anal fissure<\/strong>: This refers to a split or tear in the skin and mucosa around the anus. When this happens, the pain is usually greater than the amount of bleeding. Blood is often noted coating the stools or on wiping. The treatment of anal fissures is usually office-based and rarely involves surgery<\/li><li><strong>Colitis or proctitis<\/strong>: <strong>inflammation<\/strong> of the inner lining of the colon or rectum can lead to significant fresh bleeding. The causes are varied and include bowel infection, bowel ischaemia, vasculitis or after radiation therapy.<\/li><li><strong>Inflammatory bowel disease (IBD)<\/strong>: people with an IBD may experience rectal bleeding, but this is often accompanied by other symptoms of severe abdominal pain, bloody diarrhoea, weight loss and fever<\/li><li><strong>Polyps<\/strong>: This refers to a growth within the large intestine or rectum. Large polyps can be a cause of bleeding or mucus secretion. These have a high risk of cancer. Depending on the type, even smaller polyps may turn cancerous if left untreated<\/li><li><strong>Colon or rectal cancer<\/strong>: bleeding is often one of the first or only symptoms of <a href=\"https:\/\/thomashosurgery.com\/zh\/service\/colorectal-cancer-surgery\/\">cancer in the colon<\/a> and rectum. Blood vessels on the surface of the cancer are fragile and bleed easily with the passage of stools.
