Doctors use a camera-tipped scope to examine the inside of the colon. A colonoscopy can help diagnose the causes of internal bleeding, changes in bowel movements, abdominal pain, or unexplained weight loss. For accurate and smooth results, patients should note the following:

Do not consume solid food for at least 24 hours before the procedure. This ensures the bowel is completely empty and free of stool during the colonoscopy. Eating anything (other than clear liquids) too close to the examination time may obstruct the doctor's view through the camera.

Discontinue medication use as it can affect the colonoscopy. Blood thinners increase the risk of bleeding complications. Patients should also stop taking iron and fiber supplements, and medications for diabetes and obesity, 5 days before the procedure. These medications can slow digestion and reduce the effectiveness of the colonoscopy.

Avoid red, blue, or purple liquids as these colors can stain the colon, potentially leading to misinterpretations during the colonoscopy and inaccurate diagnoses.

Refrain from alcohol as it can cause dehydration and interact with some medications used during the procedure. Patients should stop consuming alcohol, beer, and other alcoholic beverages 2-3 days prior to the colonoscopy.

Do not eat high-fiber foods like oatmeal, bran, beans, or broccoli. While these foods are good for the gut, they can interfere with bowel cleansing and affect the results. Patients should reduce their fiber intake at least 5-7 days before the examination to allow for a detailed examination of the colon and accurate results, minimizing the risk of injury.

In addition to these restrictions, patients should prepare themselves mentally and reduce stress. The day before the procedure, patients should have a light breakfast and avoid any solid foods afterward. Discuss current health conditions with the doctor for appropriate adjustments.
