I did one of my term papers last year on Gastric banding and it's pros and cons.
Here's my few thoughts:
- I have no issues with the eligible wanting/undergoing the surgery, just SO LONG as they understand the risks. There is risk in every surgery/procedure. Be sure you learn them all thoroughly and make the best informed decision possible.
- I think people view this as too much of a quick fix. But if you have legitimately tried all options (down the paths of diet, exercise, medications etc ) and have your doctors support then that's another thing.
Something to keep in mind, is be prepared to really look after your eating habits. The stomach has the ability to stretch to encompass how much you eat, so if after the surgery (obviously post recovery periods and getting back into normal life) you slowly return to your normal amount of eating (if the source of your weight is overeating) then you will actually put back the weight and potentially destroy your stomach.
Just make sure you do ALL your research before making any decisions :) There's no rush if your life is not currently in danger.
