Description of intervention(s) / exposure
This is an observational study on subjects who are undergoing gastric banding for obesity - the initial visit will take place before surgery and the follow-up visit will take place 6 months later.. The study itself has no interventions. Study subjects will be matched with controls and they will have a one off visit around the time of the 6 month follow up for the surgery patient.
