Both gastric balloon and sleeve gastrectomy are interventions for weight loss, but they have different mechanisms and goals. Which method is “better” depends on the individual’s goals, requirements, and preferences. Here are the main differences and advantages of each method:           Gastric Balloon Procedure: A balloon is inserted through the mouth into the stomach and filled to create a feeling of fullness. Invasiveness: Minimal invasiveness. It is an outpatient procedure. Duration: The balloon typically remains in the stomach for 6 months before removal. Weight Loss: Often more moderate than with surgical procedures. Return to Normal: After balloon removal, the stomach returns to its original state. Risks: Nausea, throat irritation, or very rarely, balloon rupture. Sleeve Gastrectomy Procedure: A large portion of the stomach is surgically removed, giving the stomach the shape of a “sleeve.” Invasiveness: It is a surgical procedure that requires hospitalization. Duration: The procedure is permanent and not reversible. Weight Loss: Often more significant and enduring than with a gastric balloon. Return to Normal: Not possible as it is a permanent procedure. Risks: Like any surgical procedure, there are risks such as infection, bleeding, or scarring. Conclusion Gastric balloon is particularly suitable for individuals aiming for moderate weight loss or preparing for a larger surgical intervention. Sleeve gastrectomy is often recommended for individuals with a high BMI seeking permanent and significant weight loss. Before choosing either of the procedures, thorough consultation with a specialist in bariatric surgery should be considered.
