  • Reduction of medication use – By 12 months after the surgery, medications for diabetes, hypertension, and hyperlipidemia declined by 76%, 51%, and 59%, respectively. (Procedures were not specified in the study)61

Risks

There are risks with any surgery, such as adverse reactions to medications, problems with anesthesia, problems breathing, bleeding, blood clots, inadvertent injury to nearby organs and blood vessels, even death. Bariatric surgery has its own risks, including failure to lose weight, nutritional or vitamin deficiencies, and weight regain. Patients should consult their physicians to determine if this procedure is appropriate for their condition.

Economic outcomes

While the cost of Laparoscopic Adjustable Gastric Banding surgery ranges from $10,000 to $15,000, and the cost of Roux-en-Y Gastric By-pass surgery is $15,000 to $25,0000, payors can expect to realize a return on investment within 2 to 4 years.42
