Hi I would like to know if it is necessary for any particular diet to follow before the banding. My friend did it 4 years ago, she did not follow any pre operation diet. And even I was consulting another Gastric surgeon, he even told me that it is not necessary. Can any one give me suggestions on these...Also my doctor has told me to perform an ultra sound scan of abdomen. Did anyone else do that? He is charging a very high fee for that? Can I skip that?
