How To Decide Which Bariatric Surgery To Have

Which Bariatric Surgery Should I Get?

How Do I Decide Which Bariatric Surgery I Should Have?

To decide which bariatric surgery to have, it's important to understand the differences between the four main types: gastric bypass, sleeve gastrectomy, adjustable gastric banding, and biliopancreatic diversion with duodenal switch. Consider factors such as your health goals, medical history, and potential risks associated with each procedure. Consult with a qualified medical professional who can provide personalized advice and recommendations based on your specific situation. Prepare for the consultation by having a list of questions and being transparent about your medical history and lifestyle habits.

 

Types of Bariatric Surgery

There are four main types of bariatric surgery:

  1. Gastric bypass (Roux-en-Y): In this procedure, a small stomach pouch is created, and the small intestine is connected to this new pouch. This limits the amount of food you can eat and reduces the absorption of nutrients, resulting in weight loss.
  2. Sleeve gastrectomy: The surgeon removes a large portion of the stomach, leaving behind a smaller, tube-like structure. This reduces the stomach's capacity, leading to a feeling of fullness with smaller amounts of food.
  3. Adjustable gastric banding: A silicone band is placed around the upper part of the stomach, creating a small pouch. The band can be adjusted to control the size of the opening between the pouch and the rest of the stomach.
  4. Biliopancreatic diversion with Biliopancreatic diversion with duodenal switch (BPD/DS): This complex procedure involves removing a large part of the stomach, similar to sleeve gastrectomy. The surgeon also reroutes the small intestine to bypass a significant portion of it, reducing nutrient absorption.

How Bariatric Surgery Aids Weight Loss

Bariatric surgeries help individuals lose weight through three primary mechanisms:

  1. Restriction: By reducing the stomach's size or creating a smaller pouch, the amount of food that can be consumed at one time is limited, leading to a reduced calorie intake.
  2. Malabsorption: Some procedures, like gastric bypass and BPD/DS, involve altering the small intestine's configuration, which reduces the absorption of nutrients and calories.
  3. Hormonal changes: Certain surgeries, such as sleeve gastrectomy, affect the production of hunger and satiety hormones, leading to a decreased appetite and increased feelings of fullness.

Short-term and Long-term Differences between the Four Types of Bariatric Surgeries

Gastric bypass (Roux-en-Y)

  • Surgery time: 1.5 hours
  • Hospital stay: 2–3 days
  • Recovery time: About 2–4 weeks
  • Not reversible, in most cases

Short-term differences: Gastric bypass often leads to rapid weight loss in the first few months. Patients may experience side effects like nausea, vomiting, and difficulty eating large meals. Nutritional supplementation is usually required due to the malabsorptive aspect of this surgery.

Long-term differences: Gastric bypass offers significant and sustained weight loss, averaging around 60-80% of excess weight. However, patients must adhere to strict dietary guidelines and may require lifelong vitamin and mineral supplementation. The procedure is not easily reversible, and potential complications include dumping syndrome and bowel obstruction.

Sleeve gastrectomy

  • Surgery time: About an hour
  • Hospital stay: 2–3 days in hospital
  • Recovery time: 2–4 weeks
  • Not reversible
  • Decreased risk of dumping syndrome

Short-term differences: Sleeve gastrectomy results in relatively rapid weight loss, typically reaching 50% of excess weight within six months. Early side effects may include nausea, vomiting, and a temporary aversion to certain foods, making the adoption of appropriate nutrition and bariatric foods crucial.

Long-term differences: Patients can expect to lose around 60-70% of their excess weight within two years. Although the stomach's capacity is permanently reduced, there is less risk of malabsorption compared to gastric bypass. Long-term complications may include acid reflux, strictures, and weight regain.

Adjustable gastric banding

Short-term differences: The initial weight loss with gastric banding is slower compared to other procedures, with a gradual loss of 25-35% of excess weight in the first year. Common side effects include nausea, vomiting, and difficulty swallowing.

Long-term differences: Gastric banding typically leads to a total loss of 40-60% of excess weight over time. The procedure is reversible and adjustable, allowing for more personalized weight loss management. However, the long-term success rate is lower compared to other surgeries, and patients may experience band slippage, erosion, or need for reoperation.

Biliopancreatic diversion with duodenal switch (BPD/DS)

Short-term differences: BPD/DS is associated with rapid weight loss in the first few months, similar to gastric bypass. Patients may experience diarrhea, foul-smelling stools, and nutritional deficiencies, requiring close monitoring and supplementation.

Long-term differences: BPD/DS results in significant and sustained weight loss, averaging 70-90% of excess weight. It is particularly effective in treating obesity-related conditions like type 2 diabetes. However, due to the complexity of the procedure, there are higher risks of complications, including malnutrition, vitamin and mineral deficiencies, and bowel issues. Lifelong nutritional management is crucial for patients undergoing this surgery.

Seeking Expert Advice

Preparing for the consultation

  • Questions to ask your surgeon: Prepare a list of questions about the procedures, risks, recovery process, and any other concerns you may have.
  • Information to provide during the consultation: Be transparent about your medical history, weight loss goals, and lifestyle habits to help your surgeon make the best recommendation for you.

Understanding your surgeon's recommendation

Listen carefully to your surgeon's advice and ask for clarification if needed. Take time to consider their recommendation before making a decision.


Support Systems and Resources

Having a strong support system throughout your weight loss journey can help you overcome challenges and achieve lasting success. Seek out friends, family, and support groups who can provide encouragement and understanding as you embark on this new chapter in your life.
