4everhopeful,
I'm glad this helped you. I only have a minute to be online right now, so, real quick:
If a person is still able to swallow pills, they don't have to go through the tube. I can't though, and I put tablets in a crusher, to break up into smaller bits, then put in water to dissolve the rest of the way. Some people use a mortise and pestle to crush to a powder. All of my vitamin supplements are liquid, very nice to not have to taste them. 8)
The doctors choose where the PEG will be placed at the time of the procedure. I think what they do is shine a light from inside the stomach (fed down the esophagus) and place the incision where it is clearest i.e. more light comes through. Something having to do with avoiding as many blood vessels maybe? That's why we on the forum have various placements. You definitely could ask if it could be used, couldn't hurt to ask. My only request was to have it as close to the middle as possible, so I could see what the heck I was doing when using it.
I have heard of folks adding small quantities of alcoholic beverages through the tube. On my birthday my guys here at home thought it would be funny to give me a couple of shots of vodka through it. It must not have been enough cause it didn't get me loopy (their main mission lol) I'm so glad I can entertain them ha ha.
So long as a person can sip or snack safely, they can still eat and drink by mouth even though they have a PEG. I get nutrition both ways.
