Welcome to the forum. The peg does make a difference in energy levels because you get so many more calories per feeding. With my dad (Bulbar Palsy) it took him forever to try to eat. He would have a hard time swallowing due to Bulbar Palsy / swallowing problems. This was so much easier, he would feed through his peg and be on his way. It also helped him stop losing so much weight. I would not wait to long to get the PEG, Some PALS wait to long to get it and some are stuck with the breathing tube because they have to do the surgery quick because of compromised throat issues. I have heard on this site where they did not use the breathing tube for the surgery though. I guess it depends on the Dr. & hospital. You can still eat the regular way & PEG too.
The surgery was like 20 minutes long and there was not a lot of pain. Dad came home the next day. It's better to have it in place and not need it, then to need it and not have it or too late to put it in. With my dad, some insurance companies will not pay for it if you can still eat. All dad could eat was apple sauce and Ice Cream, we could not let anyone at the hospital know that. I guess this is where it is ok to tell a little white lie sometimes. It also made it easier to take his meds. He would crush them, add a little water and put it in his PEG. When he usually took his meds before the PEG, sometimes they would be stuck and he would not be able to get them down. Good Luck to you & I am sorry you have to be here. Alot of wonderful, smart people on this site that are more then willing to give advice on everything. Alot of people here have already been there, did that.
