Gastric Sleeve Surgery in Illinois: What to Know
Illinois offers robust options for gastric sleeve surgery. Northwestern Medicine Medical and Surgical Weight Loss Center at Huntley Hospital boasts nearly 20 years of experience and over 4,000 surgeries with zero mortality. Several facilities, including Rush University Medical Center and Loyola Medicine, are recognized Centers of Excellence. Innovative techniques like single-incision laparoscopic surgery (SILS) are available, aiming for faster recovery and better cosmetic outcomes. For those seeking non-surgical alternatives, Endoscopic Sleeve Gastroplasty (ESG) is offered at UChicago AdventHealth in LaGrange and Rush University Medical Center, reducing stomach size without incisions.
While Chicago-area costs are competitive, you'll find varying prices across the state. Consider Springfield Clinic's Surgery Center, one of fewer than 20 nationally accredited to perform bariatric surgery in a free-standing ambulatory surgery center, potentially offering a different cost structure. Verify current pricing directly with providers.
