Services
Laparoscopic Gastric Bypass
This minimally invasive procedure creates a smaller stomach pouch and reroutes the digestive system to promote significant weight loss. Ideal for patients with severe obesity, it combines restrictive and malabsorptive techniques for long-term results. Our surgeons use advanced laparoscopic methods to ensure faster recovery and reduced scarring.
Laparoscopic Sleeve Gastrectomy
A procedure removing 80% of the stomach to create a banana-shaped sleeve, reducing hunger hormone production. Effective for patients seeking substantial weight loss without intestinal rerouting. Our team employs precision techniques to maintain digestive function while achieving metabolic improvements.
Orbera Non-Surgical Balloon
A temporary, non-surgical solution involving a balloon placed in the stomach to create fullness. Combined with nutritional counseling, it helps patients lose 10-15% of body weight over six months. Our program includes personalized support to maximize results before balloon removal.
Revisional Bariatric Surgery
Specialized procedures addressing complications or insufficient results from prior weight loss surgeries. Our experts evaluate each case to determine optimal revisions, including conversion to different procedures. We focus on restoring metabolic health while minimizing risks in complex cases.
Hiatal Hernia Surgery
Minimally invasive treatment for hiatal hernias causing acid reflux and discomfort. Our surgeons reinforce the diaphragm opening while addressing obesity-related complications. The procedure often combines with bariatric surgery for comprehensive digestive and weight management solutions.
