A colorectal examination is a medical procedure used to assess the health of the colon and rectum. It typically involves a visual inspection using a flexible tube called a colonoscope, which is inserted through the anus to examine the inner lining of the lower digestive tract. This examination helps detect abnormalities such as polyps, inflammation, or signs of cancer. Patients may be advised to follow specific preparation guidelines, including dietary restrictions and bowel cleansing, to ensure clear visibility during the procedure. The examination is usually recommended for individuals over a certain age or those with a family history of colorectal cancer.
