Diagnosis & Testing
Testing For Rectal Bleeding
In addition to a digital rectal examination, a proctoscopy can be performed as an outpatient procedure to examine the inside of the lower rectum and the anus.
A faecal occult blood test (FOBT) can also be ordered to detect hidden blood in the stool sample. If your stool shows blood on testing, you will likely undergo a colonoscopy to identify abnormalities in the colon and rectum.
Direct visualisation of the colon via colonoscopy is also recommended for individuals at high risk of developing colorectal cancer: those with a family history of colorectal cancer or a personal history of polyps, and who are 50 years of age and above.
How Does Colonoscopy Work?
A colonoscopy involves inserting through the anus, and into the rectum and colon, a thin and flexible tube with a light and camera attached (colonoscope). Done under sedation, a colonoscopy is a minimally-invasive procedure that also allows for prompt removal of polyps (abnormal growths) which will be sent for biopsy to determine if they are precancerous.
The treatment for rectal bleeding depends on the chief cause of the bleeding, which only a doctor can pinpoint. If you have been seeing blood in your stools, take heart that a colorectal specialist can address your concerns, and offer timely intervention.

This depends on the cause of the rectal bleeding. The best way to prevent rectal bleeding is to prevent its causes and lower its risk factors. Some causes, like haemorrhoids and anal fissures, can be well managed with lifestyle changes and conservative treatments if treated in its early stages. Speak to a colorectal specialist to understand your management options.
