I'm over waight IV lost 4stone on my own bt finding it hard to get any more waight off and now am thinking of geting the gastric balloon is it worth it?

It depends,,, It depends on how heavy you are now and how much you want to lose. It your really heavy and need to lose a lot , it might be worth it. This seems like a relatively noninvasive procedure where little/no surgery is involved, but it may not be tolerated well. If you don't need to lose a lot more keep dieting. The safest procedure is one that doesn't have to be done. Good luck.
