Millions of Americans turn to diet, fitness, and medication first to treat their obesity. Unfortunately, studies indicate that some people will not achieve significant long-term weight loss through diet and behavior modification regimens alone.1 Those who are seriously overweight have an even greater challenge when it comes to sustaining weight loss and improving their health conditions. Surgery may remain the best option for these individuals when it comes to losing weight and keeping it off.
Weight Loss Surgery Options
If non-surgical methods have not helped you lose weight long-term, you still have another option. Studies demonstrate that weight loss surgery, as compared to non-surgical treatments, yields the longest period of sustained weight loss in patients who have failed other therapies.1 But keep in mind that a positive attitude, self-discipline, and the ability to plan ahead are key to the success of the surgery. Surgery can help you achieve your long-term goal only if you are ready to make a commitment to losing weight and keeping it off.
There are several categories of weight-loss (bariatric) surgery:
- Restrictive - Reduces the amount of food the stomach can hold but doesn't interfere with normal digestion of food and nutrients.
- Malabsorptive - Shortens the digestive tract to limit the number of calories and nutrients that can be absorbed.
- Combination - Restricts the amount of food the stomach can hold and reduces the number of calories absorbed by altering the digestive tract.
The two most commonly performed weight loss procedures in the United States are the gastric sleeve and the gastric bypass (combination procedure) and the lap band®, also referred to as laparoscopic adjustable gastric band (restrictive procedure).
