Weight Loss Surgery - Surgical Procedures for Weight Management

Weight loss surgery, or bariatric and metabolic surgery, changes the digestive system. This helps people lose a lot of weight for a long time. It also makes health problems linked to obesity better, like diabetes, heart disease, and sleep apnea. Surgeons use different methods, such as gastric sleeve, gastric bypass, adjustable gastric band, and biliopancreatic diversion with duodenal switch.

Types of Weight Loss Surgeries

There are different types of weight loss surgeries. They are also called bariatric or metabolic surgeries. Each has its unique way of helping patients. In the United States, some common ones include gastric sleevegastric bypassadjustable gastric band, and biliopancreatic diversion with duodenal switch (BPD/DS).

Gastric Sleeve

Gastric sleeve is a popular option in the United States. During this surgery, about 80% of the stomach is removed. The remaining part looks like a banana. This change helps people eat less and feel full quickly. It also adjusts the hormones and bacteria that control hunger and metabolism. Gastric sleeve surgery is not reversible.

Gastric Bypass

Gastric bypass is another surgery choice. It involves creating a small stomach pouch and bypassing a portion of the small intestine. This means less food is eaten and fewer nutrients are absorbed. It also alters hormones and bacteria related to appetite and metabolism. This surgery is hard to reverse.

Adjustable Gastric Band

The adjustable gastric band is placed around the top of the stomach to make a small pouch. This leads to feeling full after eating only a small amount. A doctor can increase or decrease the tightness of the band by adding or removing fluid. This surgery is not as common now because of its risks and lower weight loss results.

Biliopancreatic Diversion with Duodenal Switch (BPD/DS)

This surgery begins with a gastric sleeve. Then, the small intestine is changed to allow food and digestive juices to mix later. Although it helps in losing more weight, there's a higher risk of health problems and nutrient loss.

Eligibility and Preparation

If you're thinking about weight loss surgery, first, know the rules. You might qualify with a high BMI. Or, if you're not sure what your BMI is, having significant health troubles because of your weight could also make you eligible. Doctors will look at your physical and mental well-being to check if surgery is safe. They also want to make sure you're ready to change your life forever. This includes changing what you eat, moving more, and saying no to tobacco. These changes up your chances for a successful surgery.

Surgical Procedures

Surgeries for losing weight are often done with tiny cuts and a camera. This way is easier on the body and means less pain afterward. The goal is to change how much food your stomach can hold or how well your body uses what you eat. The kind of surgery you get will decide what the doctors do inside you. Your doctor might suggest a gastric sleeve, bypass, band, or another type based on your needs.

Potential Risks and Complications

Like everything in life, weight loss surgeries have risks. Some of these are short-term, like bleeding and infections. Others you have to be careful about for years, such as nutrition problems or needing more surgeries later. More complex surgeries might have more risks1. But, if you do your part by closely following up with doctors and taking the right supplements, you can keep these risks low. Remember, these surgeries are just the start of your health journey.

Conclusion

Weight loss surgery is a powerful approach for reaching significant and long-lasting weight loss. It also helps improve health issues related to obesity.

However, these operations are serious and should not be taken lightly. They require serious planning, have their risks, and need a commitment to a new lifestyle. Patients should decide with a team of healthcare experts if surgery is the right step. This team can help make sure the surgery is successful and safe.

Choosing the right patients for bariatric surgery, having skilled surgeons, and providing ongoing support are crucial steps. These steps ensure the best results from the surgery. Studies show that Roux-en-Y surgery is often the best way to lose weight and keep it off. It's better than just making lifestyle changes alone. Bariatric surgery is also seen as a better way to deal with type 2 diabetes than non-surgical methods.

In younger patients, bariatric surgery might be a more cost-effective choice. This is compared to people over 55 years old. Adding a Very Low-Calorie Diet (VLCD) to weight programs isn’t always the best choice. But it can be a good option when looking at general obesity trends. Weight management plans with VLCDs show the best weight loss after a year. Also, diets that are low in carbs, high in protein, or use meal replacements result in slightly more weight loss after a year.

After bariatric surgery, long-term issues and side effects are a concern. Regular check-ups and care after surgery are very important. Studies also mention differences in how different races might fare after bariatric surgery. This shows the need to address health disparities in this area. When selecting patients, providing top-level surgery, and offering good follow-up care, the benefits of bariatric surgery can reach everyone who needs it.
