Have you ever asked, “Which weight loss surgery is right for me”? Over the years, numerous weight loss surgery options have been developed to address the concerns of a diverse group of patients. Today, we take a look at the seven primary types of weight loss surgery in an effort to help you decide which solution might be best for you.
1. Gastric Band
Was a popular surgery to lose weight in the past but lost favor over the last 8 years , a silicone band (adjustable via saline water injections) is placed around the upper portion of the stomach to restrict food intake. On average, patients lose approximately 40% of excess weight as an average .¹ This surgery was a good choice for those not interested in more permanent surgeries, as the band can be removed if necessary.
2. Gastric Bypass
Perhaps the one of the best surgeries to lose weight for the extremely obese, The procedure surgically reduces stomach size and re-routes the intestines, changing the way the body absorbs calories and nutrients. As a result, patients can lose up to 85% of excess weight in one year.² Because this option is quite permanent, gastric bypass is often recommended for the morbidly obese and diabetic individuals.
3. Gastric Sleeve
Is the most popular weight loss surgery, restricts the stomach to about 20% capacity, making the patient feel full faster and feel less hungry due to reduced hunger hormone production. On average, gastric sleeve patients see weight loss averaging 60 to 70% of excess weight in the first year.³
4. Gastric Balloon
The gastric balloon restricts food intake not by pinching or surgically altering the stomach, but by inflating up to three medical-grade balloons inside it to take up space and make patients feel full faster. Patients can lose as much as a third of their excess weight in 6 months, the balloons has to be removed at that time.⁴
5. Duodenal Switch
Similar to the gastric bypass, the duodenal switch involves reducing stomach size and rerouting the small intestines, causing severe malabsorption, patients after this procedure can see weight loss in excess of 70% of their excess weight in one year.⁵
The procedure is generally uncommonly used.
6. vBloc Therapy
In contrast to stomach restriction methods, vBloc therapy involves implanting a rechargeable vagal nerve stimulation device to reduce the physical feelings of hunger. ThevBloc device blocks the nerve’s “hunger signal” for a period of time, naturally reducing appetite. In the first year, patients may lose about a quarter of their excess weight.
The AspireAssist system connects an internal device in the stomach to an external port via a tube. After eating, the patient can manually empty a third of the stomach contents, directly reducing calorie absorption. In the first year, patients could lose about 28% of their excess weight.⁶ This solution may not be recommended for those who have been previously diagnosed with an eating disorder such as bulimia or anorexia.
