Prospective Clinical Study to Evaluate the Metabolism Using the Breezing Device in the Preoperative and Postoperative Periods of Gastric Bypass in Patients With Type II Diabetes.

Objective of the research:

Primary To evaluate the systemic metabolic rate of diabetic patients before and after bariatric gastric bypass surgery using the Breezing® device.

Secondary

• To measure the indirect metabolic rate by quantifying O2 gas consumption (g) and CO2 gas release (g);
• To analyze the 'population impact', that is, to measure using statistical tools how many cases of metabolic maladjustment could be prevented if the diabetes risk factor were to be eliminated;
• To correlate, by means of a regression test, if there is any dependence between the metabolic rate and the diabetes risk factor;
• To validate the accuracy of the Breezing® device.

Evaluation of the risks and benefits Risks As the patient only needs to blow on the Breezing® device using a small straw (blower), the direct risks are minimal, perhaps contamination due to failure to exchange the blower. Thus, the risks are indirect and are more associated to the malfunctioning of the device.
