Martin refused the PEG for 4 weeks, but he was getting thinner and thinner, it was painful to see he looked like a grass hopper. He went from 12 stones to 9 stones and measures 6ft 2.(The weight converter told me 12st=168pounds and 9st=126pounds I am not sure this is right it seems a bit small to me.)
On the 5 weeks he gave in to the dietician and me pressuring him. He was so weak from the treatment the PEG was a God send. I was able to work from home almost every day for 2 weeks and I could feed him and make sure he stayed hydrated.
SO if it is offered go for it, it will stop you loosing weight and weakening, and you will be avoiding all sorts of problems.
