pay attention after your next (first?) colonoscopy. they pump you full of air and most of it comes out the same direction it came in.

just don’t hold it. my mother was feeling too dainty to fart (we had back to back colonoscopies with the same gastro. even did the prep together. what a bonding experience) so she ended up with trapped gas. and then did not get enough dilaudid and only got to the gut clench phase of the drug and ended up in more pain.

then she farted the long fart and all was right in the world again. but her gut was still clenched from the drug so it was not so pleasant.
