At Jet Medical Tourism®, we understand your situation. It is our goal to provide you with education to help you evaluate your Mexico weight loss surgery options.

Take the next step by reviewing the side-by-side comparison of the differences between gastric sleeve vs gastric bypass vs lap band vs duodenal switch.

Different types of bariatric surgery include gastric sleeve surgery, RNY gastric bypass surgery, gastric banding or Lap-band surgery and duodenal switch surgery.

4 Categories and types of bariatric surgery

There are four categories of bariatric surgery that help promote weight loss in different ways.

  • Restrictive Surgery: Reduces the amount of food the stomach can hold without interfering with normal digestion of food and essential nutrients.
  • Malabsorptive Surgery: The digestive tract is shortened to limit the absorption of calories and nutrients from food.
  • Hormonal: Removal or avoidance of the stomach’s upper portion (fundus) results in a decrease in gherlin levels (hunger hormone).
  • Combination: Restricts the amount of food the stomach can hold and reduces absorption of calories through surgical alteration of the digestive tract.

How it
Promotes
Weight Loss
  • Restrictive
  • Limits food intake
  • Reduces hunger sensations by removing Ghrelin (hormone that plays a key role in regulating body weight)
  • Restrictive & Malabsorption
  • Limits food intake
  • Reduces absorption of calories and nutrients
  • Restrictive
  • Limits food intake
  • Slows digestion
  • Creates fullness
  • Restrictive & Malabsorption
  • Limits food intake
  • Food bypasses 45-60% of the small intestine, resulting in higher malabsorption and greater weight loss
Change
to Intestine
  • No change to the intestine during gastric sleeve surgery
  • Small intestine is cut and bypassed during RNY gastric bypass surgery
  • No change to the intestine during gastric banding surgery
  • Reroutes "switch" a portion of the small intestine during duodenal switch surgery
Change
to Stomach
  • Stomach Size is Reduced
  • 60-80% of the stomach is removed, leaving a vertical narrow pouch 2-3 oz (60-100 cc)
  • New Stomach Created
  • Stomach is divided into a small upper pouch 1 oz (20-30 cc) and a larger lower pouch
  • Stomach Size is Reduced
  • An adjustable silicone ring (band) is placed around the top part of the stomach creating a small 1-2 oz (15-30 cc) pouch
  • Stomach Size is Reduced
  • 70-80% of the stomach is removed, creating a new small stomach (similar to gastric sleeve)

Choosing the right type of bariatric surgery

Before undergoing weight loss surgery, you’ll want to learn about the benefits of bariatric surgery and associated bariatric surgery risks. Not all patients will benefit from the same procedure so its important to understand the different types of bariatric surgery in more detail.

Gastric sleeve surgery

Gastric Sleeve Surgery is a permanent weight loss surgery that reduces stomach capacity and food intake. First, the smaller stomach limits the amount of food you eat. Second, the hunger hormone ghrelin is removed so appetite and feelings of hunger are lowered.

Gastric bypass surgery

Gastric Bypass Surgery is the most commonly performed bariatric surgery worldwide. It is highly effective at resolving many obesity-related diseases. Patients who choose gastric bypass can lose 70% of their excess body weight within 12-18 months.

Lap band surgery

Lap Band Surgery is the safest type of bariatric surgery, but requires routine follow up for band adjustments. Patients who choose lap band typically lose 40% of excess body weight gradually over time.

Duodenal switch surgery

Duodenal Switch Surgery is a type of bariatric surgery that removes a large portion of the stomach and changes the digestive tract. Patients eat less and their body absorbs fewer calories, which results in more weight loss compared to other surgical procedures.
