Surgical Weight Loss Options
Laparoscopic Sleeve Gastrectomy
A minimally invasive procedure that reshapes the stomach into a smaller sleeve to limit intake, curb hunger, and support significant weight loss.
Laparoscopic Gastric Bypass
A proven, minimally invasive procedure that reshapes the digestive system to reduce intake and support major, lasting weight loss.
Gastric Band System
An adjustable band placed around the upper stomach to control portions and support gradual, manageable weight loss.
Orbera Intragastric Balloon
A non-surgical, temporary balloon that encourages portion control and jump-starts weight loss without incisions.
Endoscopic Sleeve Gastroplasty
A minimally invasive, incision-free procedure that reduces stomach size using an endoscope for a shorter recovery.
Revisional Bariatric Surgery
Corrective procedures for patients seeking better results or relief from complications after a previous weight loss surgery.
