The purpose of this prospective study was to evaluate the effect of compliance versus noncompliance with a behavior modification program (BMP) for 35 patients who underwent implantation of 51 Garren-Edwards gastric bubbles (GEGB). Criteria for morbid obesity was met by every patient. Two patient groups were formed by self-selection. Compliant patients (group I) attended 75% or more of the BMP. Group II consisted of noncompliant patients, and was divided further into partially compliant and totally noncompliant. A significant difference was found in both loss of weight and loss of body mass index (MBI) between the compliant and noncompliant groups, with no significant difference in weight loss between the partially and totally noncompliant groups. Patients' compliant or noncompliant behavior had a significant effect on changes in weight (p = 0.007) and body mass index (p = 0.005). Sixteen patients had two consecutive bubble implants. The rate of compliance was significantly higher during the first implant program, with a significantly greater loss in both weight and BMI for compliant patients. Follow-up data for 28 of 35 patients revealed a continued, albeit small, average weight decrease. In summary, weight loss does not result from the gastric bubble alone. Our study demonstrates that the key factor is compliance with a behavior modification program.
