Study summary

Obese patients are going to be submitted to indirect calorimetry pre-operatively and we are going to repeat the same exam 6 months after bariatric surgery (post Roux-en-Y gastric Bypass surgery). They are going to do also body composition analysis in both moments.

The investigators are going to compare the results to see if the bariatric surgery increases their energy expenditure.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 1, 2010, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
