Gastric sleeve surgery, or sleeve gastrectomy, is one of the most popular bariatric procedures for significant weight loss. It offers a permanent solution for those struggling with obesity by removing approximately 75-80% of the stomach. This procedure not only reduces the stomach’s capacity but also alters hunger hormones, helping patients achieve sustainable weight loss. But what does “permanent” truly mean in the context of gastric sleeve surgery?

At Tonic Weight Loss Surgery, we’re committed to guiding you through every step of your journey, from the decision-making process to lifelong aftercare. Here’s everything you need to know about the permanence of gastric sleeve surgery and how it can change your life.

What Does “Permanent” Mean for Gastric Sleeve Surgery?

When we say gastric sleeve surgery is permanent, it’s because the procedure involves the surgical removal of a large portion of the stomach. Unlike other bariatric surgeries, such as gastric banding, the gastric sleeve is irreversible. The stomach is reshaped into a smaller, sleeve-like structure, and the removed portion cannot be reattached.

This new, smaller stomach reduces how much food you can eat at one time and significantly decreases the production of ghrelin, the hormone that stimulates hunger. The result? You feel full faster and experience reduced appetite.
While the surgery is permanent, the long-term success of gastric sleeve surgery depends on maintaining healthy habits, including diet, exercise, and follow-up care.

How Gastric Sleeve Surgery Works

The surgery is performed laparoscopically, using small incisions and specialised instruments. Here’s an overview of the process:

Stomach Reduction:
Approximately 75-80% of the stomach is removed, leaving a sleeve-shaped stomach about the size of a banana.
Hormonal Changes:
The part of the stomach that produces ghrelin is removed, which can help reduce hunger and cravings.
No Intestinal Bypass:
Unlike gastric bypass, the digestive tract is not rerouted, which simplifies the procedure and reduces potential complications.

What Are the Benefits of Gastric Sleeve Surgery?

Effective Weight Loss:
Most patients lose 60-70% of their excess weight within the first year after surgery, with many maintaining their results long-term.
Improved Health:
The surgery can lead to significant improvements in obesity-related conditions, including diabetes, high blood pressure, and sleep apnoea.
Simpler Procedure:
Gastric sleeve surgery is less invasive than gastric bypass and avoids some of the potential complications associated with rerouting the digestive tract.
Hormonal Regulation:
By reducing hunger hormones, the surgery makes it easier to stick to a lower-calorie diet and maintain weight loss.

Is Gastric Sleeve Truly Irreversible?

Yes, gastric sleeve surgery is considered irreversible because the removed portion of the stomach cannot be replaced. However, it’s important to note that the remaining stomach can stretch over time if patients consistently overeat. This stretching can reduce the surgery’s effectiveness and lead to weight regain.

How to Maintain Long-Term Success

The permanence of gastric sleeve surgery means that the physical changes to your stomach are lasting, but maintaining your results requires commitment. Here are some tips for long-term success:

Follow a Balanced Diet:

• Focus on small, protein-rich meals.
• Avoid sugary and high-fat foods that can lead to weight regain.
• Stay hydrated but avoid drinking fluids during meals to prevent overfilling the stomach.

Stay Active:

Regular physical activity helps maintain weight loss and supports overall health. Start with light activities post-surgery and gradually increase intensity as your recovery progresses.

Take Supplements:

Nutritional deficiencies are a common concern after surgery. At Tonic, we offer specially formulated multivitamins and supplements to help you meet your nutritional needs.

Attend Follow-Up Appointments:

Regular check-ups with your surgeon and dietitian are essential for monitoring your progress and addressing any potential complications.
