People tell you that the prep for the colonoscopy is bad, but that the test itself is nothing. However, no one ever says anything about the aftermath - that time when you go home and resume eating solid food. You take a bite and chew and the enzymes in your mouth start the digestion process. You swallow, the food travels down your esophagus to your stomach, where the digestion process continues. The nutrients your body needs are absorbed and the undigestable parts proceed into your NOW COMPLETELY CLEANED OUT intestines. You can feel and hear them gurgling down that loooong tube to you know where, and you feel an urge to fart. HOLD IT!!! You need to consciously control that sphincter muscle until you are securely seated on the toilet. That will almost certainly be a wet fart! It will take several hours (days?) to get things back to normal.
