Welcome to this site. It was so helpful when I was dealing with issues. As far as the peg tube from what I have read on this site the peg tube can become loose as someone is losing weight or the hole begins to enlarge. I am sure more people will give you more information. Everyone here has be so wonderful and supportive. I know it is hard to think of anything being positive. You are unable to perform you normal activities and it is very fustrating. Being a cancer survivor I have my ups and downs but then realize that I am alive !!! Keep him in good spirits and before you know it he will be out there hitting golf balls and pulling weeds.
