When deciding on weight loss surgery options, the debate between gastric sleeve vs bypass is a frequent one. Both of these surgeries have their own set of advantages and disadvantages. The right choice varies depending on individual needs, health conditions, and desired outcomes.

 

Gastric Sleeve Surgery:

Gastric sleeve surgery, known scientifically as laparoscopic sleeve gastrectomy, is a minimally invasive procedure. It involves removing a significant portion of the stomach, resulting in a ‘narrow tube’ or ‘sleeve’ shape. Consequently reducing portion sizes permanently.

Advantages of Gastric Sleeve Surgery:

• Maintains good eating quality.
• Leads to 60 to 70% excess weight loss over time if post-operative guidelines are followed.
• Yields a 70 to 80% rate of type 2 diabetes control.
• The gastrointestinal tract remains continuous.

Disadvantages:

• There’s a 1% risk of leakage from the staple line.
• Can induce reflux in 10 to 20% of patients.

Do I Qualify for Gastric Sleeve Surgery?

• A BMI greater than 30 with weight-associated health conditions.
• A BMI greater than 35

 

Gastric Bypass Surgery: The Basics

Gastric bypass is a procedure with over 40 years of validation. In this method, the stomach is partitioned into smaller size, and a portion of the small bowel is then re-routed to this new gastric pouch. There are variations of the bypass, including the traditional Roux en Y gastric bypass and the one-anastomosis bypass, also known as the Omega loop or mini gastric bypass.

Advantages of Gastric Bypass Surgery:

• Long-established results and data.
• Achieves 80 to 90% excess weight loss.
• Has a high rate of up to 90% diabetes control.
• Effective control of acid reflux.

Disadvantages:

• Possibility of ulceration at the site of anastomosis.
• Risk of Dumping Syndrome.
• Potential for internal hernia.

Do I Qualify for Gastric Bypass Surgery?

• Typically recommended for those with a BMI over 35.
• As with the gastric sleeve, consultation with a specialist, like Mr. Siva Gounder at Perth Weight Loss and Surgery, is crucial.

 

Comparing the Two: Gastric Sleeve vs Bypass

When comparing gastric sleeve vs bypass, the most significant difference lies in their methodology and outcomes. Gastric bypass tends to have a slightly higher percentage of excess weight loss and a better track record for resolving obesity-related health problems than the gastric sleeve. However, the bypass procedure may come with a higher risk of long term complications.

While both surgeries have shown potential in improving and potentially causing remission of  Type-2 diabetes, the gastric bypass showcases a marginally better rate of 80-90% excess weight loss in the first year compared to the gastric sleeve’s 60-70%. Recovery time for both is quick, typically requiring a hospital stay of just 1-2 nights.

 

Which Is Right for You?

The decision between gastric sleeve and gastric bypass isn’t one-size-fits-all. Your individual health profile, desired outcomes, and even factors like whether you’ve had previous abdominal surgeries play a role. The presence of conditions like reflux or a history of certain surgical procedures might also influence your choice. It’s essential to consult with experienced professionals at Perth Weight Loss and Surgery to determine which weight loss surgery option is the best fit for you.
