Postoperative Dietary Counseling After Bariatric Surgery

Not Applicable

Completed

• Conditions: Obesity

• Registration Number: NCT00125073
• Lead Sponsor: University of Pennsylvania

Brief Summary

This study aims to assess the changes in physical characteristics, food intake, eating behavior, vomiting, and dumping in 100 patients who undergo bariatric surgery. Patients are put into one of two conditions; they will either receive standard postoperative care or biweekly counseling sessions with a dietician that will help them with the postoperative diet. Patients who receive dietary counseling are anticipated to experience greater weight loss and report less consumption of sugar and fat as compared to patients who do not receive dietary counseling. Moreover, patients who receive dietary counseling are predicted to report less frequent nausea, vomiting, and gastric dumping, as compared to patients who do not receive postoperative dietary counseling. This is predicted to result as a consequence of increased dietary adherence evidenced by the former group.
