Descriptive Information
Brief Title  ICMJE Resting Metabolic Rate Testing in Bariatric Surgery Patients
Official Title  ICMJE The Role of Pre-Surgical Metabolic Testing for Procedure Selection in Bariatric Surgery
Brief Summary This study evaluates if measuring resting metabolic rate (the number of calories the body burns at rest) before surgery can help predict successful weight loss after surgery.
Detailed Description This is a prospective study enrolling patients from the Baylor Weight Loss Surgery Center who have met all of the requirements to proceed with primary bariatric surgery. Patients will undergo pre-operative and post-operative metabolic testing (6 months, and 1 year after surgery) using a portable calorimeter with eventual follow up of medical record at 5 years. Data from up to 50 patients will be collected. The main objectives are to examine if the pre-operative resting metabolic rate can accurately predict successful weight loss after bariatric surgery and if it can be used to guide the selection of the type of bariatric surgery that would be most successful for the patient.
Study Type  ICMJE Interventional
Study Phase  ICMJE Not Applicable
Study Design  ICMJE Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Condition  ICMJE
  • Weight Loss
  • Bariatric Surgery Candidate
Intervention  ICMJE Device: ReeVue Indirect Calorimeter
The ReeVue Indirect Calorimeter will be used in this study to measure the resting metabolic rate. The test takes approximately ten minutes to complete. The subject should prepare for the test by avoiding stimulants and exercise on the day of the test, as well as eating meals four hours before the test. The subject will be seated during the test. They will be given a nose clip that looks like a clothes pin to be placed on their nose. A plastic mouth piece that allows all of the air they breathe to come in through the top of the mouth piece and the air they breathe out to go into the ReeVue Calorimeter will also be provided. The subject will remain in this position for ten minutes until the testing is complete.
Study Arms  ICMJE Experimental: Resting Metabolic Rate Testing
All subjects will have the resting metabolic rate test. The ReeVue Indirect Calorimeter from Korr Medical will be used to obtain the resting metabolic rate.
Intervention: Device: ReeVue Indirect Calorimeter
