Why is proper preparation for a colonoscopy so important?

The key to a properly performed examination by the doctor is adequate patient preparation.
The most important thing is to follow the instructions for the laxative preparation.
In a patient who is poorly prepared for colonoscopy and whose bowel is not properly cleansed, it is difficult to perform an accurate examination or it may be completely impossible. In such cases, the doctor may recommend repeating the procedure.
Most important:
• Take the preparation according to the instructions or the recommendations of the referring doctor
• Drink plenty of water
• Review the list of foods that should be avoided before the examination, as they may hinder proper bowel cleansing
