Introduction: Obesity is one of the most important public health problems facing the world today. Intragastric balloon (BIB) is a short term, reversible, minimally invasive method for weight loss. Furthermore, it helps changing eating habits and behavior. It promotes gastric distension, resulting in decreased intake of food, delays gastric emptying and enhances the feeling of satiety. The objective of this study was to evaluate the effects of BIB in patients with type 2 diabetes mellitus (T2DM) and overweight or with grade I obesity, by analyzing the weight loss, body composition, glucose and lipid metabolism, production of enterohormones and quality of life.

Methods: Clinical trial including 40 patients with T2DM and BMI 27-34.9 kg/m2, which underwent placement of BIB, kept for 6 months, and follow-up for another 6 months after withdrawn. A standardized meal test diet was carried out at 0 and 6 months. Glucose, insulin, triglycerides, GLP-1 active and total PYY were measured at times 0, 30, 60, 120 and 180 minutes.

Results: The total weight decreased by 15.6 ± 7.23 kg after 6 months of use of BIB, which corresponds to loss of 17.1% of the total weight. After 6 months of follow-up, mean weight loss was maintained at 13.89 kg (15.2%). There was a significant reduction in body fat mass and area of the glucose curve, insulin and triglycerides (p ranged from <0.001 to 0.003). Of the 24 patients (60%) patients with hypertension at baseline, only 3 (7.5%) remained hypertensive after using the BIB. Serum levels of active GLP-1 and total PYY decreased with BIB. The quality of life improved in all domains analyzed (p < 0.001 to 0.041): physical functioning, physical function, pain, general health, vitality, social functioning, emotional aspects and mental health.

Conclusion: BIB is effective for weight loss and control of DM2 with quality of life improvement. There is no positive correlation with the production of enterohormones.
