Obesity is a chronic multi-factorial disease associated with serious increases in adiposity, morbidity and mortality rates. Ghrelin, leptin and adiponectin complexly interact to modulate appetite and mediate metabolic processes. The objective was to evaluate the effects of Bioenteric Intragastric Balloon (BIB) versus conservative therapy (diet and physical exercise) on plasma ghrelin, leptin, insulin and adiponectin in obese subjects. A total of 128 adult consecutive morbidly obese individuals were randomized into: BIB group comprised 84 patients treated with Intragastric Balloon and control group comprised 44 obese patients treated with conservative treatment only. In BIB group, insertion of balloon caused a significant reduction in body mass over a 6-months period compared with the control group. After one month, the levels of ghrelin increased significantly then gradually decreased, reaching the starting level three months after the removal of the balloon. Also, leptin level decreased significantly. In the control group, the corresponding of ghrelin and leptin levels remained relatively stable. In BIB group, adiponectin significantly increased as opposed to a transient increase in the control group. Conclusion: intragastric balloons in association with low-calorie diet are effective, safe, reversible, but short-lasting therapeutic endoscopic intervention in obese patients. The treatment with BIB causes significant changes in the levels of appetite-regulatory hormones beside a body mass reduction, changes in carbohydrate and lipid metabolism and improved co-morbidities.
