Understanding the Gastric Sleeve Procedure
First, let's briefly review how gastric sleeve surgery works. The vertical sleeve gastrectomy (VSG), commonly known as the gastric sleeve, involves surgically removing approximately 75-80% of the stomach. This drastically reduces the size of the stomach to a narrow banana-shaped pouch, roughly the size of a small juice glass.
By shrinking the stomach, patients will feel fuller faster and consume smaller portions of food during meals. The procedure also causes hormonal changes that can decrease appetite, further supporting weight loss.
Most gastric sleeve surgery patients lose 60-70% of their excess body weight within 1-2 years after the procedure when they stick to the recommended post-op lifestyle changes. So if the scale isn't budging as expected, it's time to troubleshoot.
10 Reasons for Stalled Weight Loss After Gastric Sleeve
Here are the top culprits that can prevent effective weight loss in the months and years following VSG surgery:
1. Not Following the Post-Op Diet
One of the most common mistakes that hinder post-op weight loss? Not adhering to your surgeon's dietary guidelines. It's crucial to progress slowly through the post-op diet stages (liquids, pureed foods, soft proteins, etc.) and choose high-protein, low-carb options.
Many patients dive back into calorically dense foods like bread, pasta, ice cream, etc. too soon, overwhelming their shrunken stomach. This not only slows weight loss, but it increases the risk of uncomfortable side effects like vomiting and dumping syndrome.
2. Grazing Throughout the Day
With a tiny gastric sleeve stomach pouch, eating 3-4 small meals plus a couple protein shakes is generally enough food to get in your essential calories and nutrients each day. But many patients adopt a habit of constant grazing - constantly taking small bites of food throughout the day.
This can severely limit weight loss because you're consuming more calories than your body needs or the sleeve can handle. Make sure your mealtime routine involves eating scheduled, portion-controlled meals and leaving at least 2-3 hours between snacks/meals.
3. Not Getting Enough Protein
Dietary protein is absolutely essential for successful long-term weight and health outcomes after gastric sleeve surgery. Not only does protein help prevent dangerous muscle loss while dieting, but it also helps keep you fuller for longer by releasing gut hormones that decrease hunger and appetite.
Most post-op patients need to consume 60-100g of high-quality protein every day. It can be challenging to hit these targets on a very low-calorie or liquid diet, which is why supplementing with a whey or pea protein shake is often recommended.
4. Overdoing the Carbs and Sugary Foods
Eliminating or drastically reducing dietary carbohydrates, especially simple sugars, is key for effective weight loss after gastric sleeve surgery. Simple carbs from sources like bread, pasta, rice, sweets
