What is Colonoscopy?
A colonoscopy is a medical procedure that allows doctors to examine the inside lining of your large intestine (colon) using a thin, flexible tube with a light and camera attached called a colonoscope.
Procedure
During a colonoscopy, the patient is usually given a sedative or anesthesia to help them relax and minimize discomfort. The colonoscope is gently inserted through the rectum and advanced through the colon. The camera on the colonoscope sends images to a monitor that the doctor uses to examine the colon for abnormalities such as polyps, inflammation, bleeding, or tumors.
If any abnormal findings are discovered during the colonoscopy, the doctor may take a biopsy (small tissue sample) for further examination or remove polyps. Most colonoscopies are done as part of routine screening for colorectal cancer in individuals who are over the age of 50, or for individuals with certain risk factors or symptoms.
Colonoscopy is generally considered a safe procedure with minimal risk of complications. However, there may be some potential risks, such as bleeding, perforation of the colon, or adverse reactions to sedation or anesthesia.
Before a colonoscopy, the patient will typically need to follow certain dietary restrictions and take medication to cleanse the colon. It is important to follow the doctor’s instructions carefully to ensure a successful procedure.
Overall, a colonoscopy is an important tool for detecting and preventing colorectal cancer and other digestive conditions. It allows doctors to identify and treat any abnormalities in the colon at an early stage, which can significantly improve prognosis and outcomes.
