Weight loss can be achieved with bariatric surgery. Surgery always comes with risk and weight loss requires permanent changes after-op. Most doctors won’t consider surgery unless the patient is:
- A person with a higher body mass (BMI) than 40 or more than 100 pounds overweight, or a BMI of 35 or greater, and who has an obesity-related illness.
- Has tried traditional weight loss strategies without much success.
- Can change their diet to prevent complications and ensure that surgery works.
Gastric bypass is the most common form of weight loss surgery. It’s only one option. These are the main weight-loss surgery options so that you can find the one that suits your needs.
According to the American Society for Metabolic and Bariatric Surgery, gastric bypass surgery is a procedure that separates a portion from the stomach. This creates a small pouch. This allows food to bypass the stomach. The surgeon then connects the new stomach to the small intestine. This allows you to eat smaller meals because your stomach is smaller.
A person with a smaller stomach or small intestine may be less able digest and absorb nutrients from smaller meals.
This routine is effective for most people who lose weight. Surgery requires that you make changes to your diet over time. A person could become deficient in certain nutrients if they don’t have the right support. Gastric bypass is a complex procedure and requires a longer stay in hospital.
Sleeve gastrectomy can remove approximately 80 percent of your stomach. This procedure has a similar effect as gastric bypass. It reduces the amount of food that a person can consume. Surgery can also reduce the production of hormones because the stomach is smaller. This can make you feel fuller quicker and reduce your food cravings.
According to the ASMBS, Sleeve gastrectomy is about the same as gastric bypass and requires a shorter hospital stay. It can support weight loss by increasing feelings of fullness, and decreasing food cravings. It can also cause nutritional deficiencies, similar to gastric bypass. It can also be irreversible.
Adjustable gastric band
The adjustable gastric band is a band that wraps around the stomach’s upper part. This reduces the usable stomach area, similar to gastric bypass or sleeve-gastrectomy. The effect of this surgery is slower than other types because the doctor gradually tightens the band.
According to research, the gastric band does not limit the amount of food that a person can eat. The band may allow food to pass through it. Instead, the band might reduce hunger.
The adjustable gastric band can be reversed and has the lowest risk of complications. The adjustable gastric band is less invasive and poses a lower risk for nutritional deficiencies. It has the highest number of subsequent surgeries and weight loss tends towards being slower.
Biliopancreatic Diversion with Duodenal Switch
According to Johns Hopkins Medicine, biliopancreatic diversion (BPD/DS), also known as duodenal surgery, has two components.
A surgeon first creates a smaller stomach. This is similar to the procedure for sleeve-gastrectomy. Next, the surgeon will remove a portion the small intestine to reduce the food you can absorb. These interventions together create a smaller stomach, which can hold less food and prevents the body from gaining weight.
The duodenal switch is more effective than other methods for losing weight. This surgery is also the most effective in reducing weight-related complications such as diabetes. This surgery requires less diet management and most people can eat fairly normal meals over time. It has the highest death and complications rates, is more likely to have nutritional deficiencies, and requires regular follow-up.
