Which type of weight loss surgery is right for me?
Compare bariatric procedures to help you better understand your options
The field of bariatric surgery has come a long way in recent years. When performed by an experienced, qualified bariatric surgeon, today’s techniques are safer, less invasive, and more effective than ever, and you have a number of options to consider as a patient. This chart will help you understand the similarities and differences between the various options.
Gastric Bypass | Gastric Sleeve | Adjustable Gastric Band | ||
Procedure Type: | Inpatient Surgery, General Anesthesia | Inpatient Surgery, General Anesthesia | Inpatient or Outpatient Surgery, General Anesthesia | |
Recommended for: | BMI ≤35 | BMI ≤35 | BMI ≤30 | |
How it works: | Stomach is surgically reduced to a small pouch; upper intestine rerouted to reduce nutrient intake | Stomach is surgically reduced to a small pouch; intestines unaffected | Adjustable band device is placed around stomach to restrict capacity | |
Recovery | 3 to 5 day hospital stay; back to work in 3 to 5 weeks; exercise in 6 to 8 weeks | 1 to 3 day hospital stay; back to work in 2 to 3 weeks; exercise in 4 to 6 weeks | Possible overnight hospital stay; back to work in 1 week; exercise in 4 to 6 weeks | |
Results: | Restricts food intake & reduces nutrient absorption; achieves very rapid, significant weight loss (up to 6 lbs/week for first 6 months) | Restricts food intake, does not reduce nutrient absorption; achieves rapid, significant weight loss (up to 80% of excess weight in 1 year) | Restricts food intake, does not reduce nutrient absorption, achieves rapid, moderate weight loss (up to 65% of excess weight in 1 year) | |
Pros: | Long-term effectiveness proven by years of research; achieves greater weight loss than gastric band; no implant; shown to more effectively reduce obesity-related diabetes, sleep apnea & other conditions compared to other procedures | No nutrient malabsorption; greater weight loss potential than gastric band; no implant; improves obesity-related diabetes, sleep apnea & other conditions | No permanent change to stomach; adjustable for controlled weight loss; reversible; achieves steady weight loss: improves obesity-related diabetes, sleep apnea & other conditions | |
Cons: | Patients must take vitamin supplements for life; longer recovery compared to gastric sleeve or band; irreversible changes to stomach and intestines | Less research data available on long-term effectiveness; less dramatic weight loss than bypass; irreversible changes to stomach | Lower weight loss potential than gastric sleeve or bypass procedures; regular adjustments required | |
Possible risks include: | Nutrient deficiency, dumping syndrome, possible gastric leakage, sagging skin from rapid weight loss | Nutrient deficiency, possible staple line leakage, sagging skin from rapid weight loss | Band slippage or leakage requiring another surgery |
Duodenal Switch | Gastric Balloon | |
Procedure Type: | Inpatient Surgery, general anesthesia | Non-surgical, sedation anesthetic |
Recommended for: | BMI ≤40 | BMI 30 to 40 |
How it works: | Stomach is surgically reduced to a small pouch; upper intestine rerouted to connect stomach to the intestinal tract at a lower point; gall bladder is also removed in some cases | A biocompatible, FDA approved device is inserted through the mouth into the stomach and inflated to fill space; balloon is removed after 6 months |
Recovery: | 2 to 3 day hospital stay; back to work in 2 to 3 weeks; back to exercise in 4 to 6 weeks | Back to work and exercise in 3 to 5 days |
Results: | Restricts food intake, reduces appetite and lowers nutrient absorption, achieves very rapid, significant weight loss (average 70% excess weight lost in 1 year) | Reduces food intake and helps patients feel full longer by reduce space inside the stomach; achieves 20 to 50 lbs. weight loss |
Pros: | Lower rate of weight regain compared to other procedures, permanently reduces stomach volume; improves or eliminates obesity-related diabetes, sleep apnea & other conditions | Reduces hunger and food intake without surgery; provides temporary solution for significant weight loss; avoids risks associated with surgery |
Cons: | Complex surgery that requires experienced specialist; longer recovery compared to gastric sleeve or band; irreversible changes to stomach and intestines; patients must take vitamin supplements for life | Temporary; appetite will return to previous level after balloon is removed; not recommended for severely obese patients |
Possible risks include: | General anesthesia risks, staple line leaks , intestinal perforation or strictures (rare), gallstone formation, increased risk of bone fractures | Balloon deflation; nausea and vomiting; stomach pain for several days after procedure |
