Gastric sleeve surgery, also known as sleeve gastrectomy, is a popular weight loss procedure, and one of the most commonly performed by surgeons here in Queensland. It involves removing a portion of your stomach to promote significant weight loss. If you’re thinking about gastric sleeve surgery, it’s natural to wonder how much weight you can expect to lose. And there is no one answer, as every body is different, however there are averages we can look toward. It’s important to note, there can be many factors which influence weight loss, which I’ll discuss. I’ll also delve into the factors that positively influence weight loss after gastric sleeve surgery. Hopefully, it provides you with a realistic understanding of the amount of weight you can potentially lose and the best way to get there.

The initial weight loss phase
The anatomical and metabolic changes caused by the gastric sleeve procedure generally result in rapid weight loss after gastric sleeve surgery. Steady weight loss usually continues for the first 12 – 18 months. During this time, patients lose on average about 60-70% of their excess body weight.
If you are experiencing easy weight loss in this time, it can be tempting to let the surgery do all the work as your weight comes down, but this would be a mistake. The first 12 months are what we call a “honeymoon phase” where we see the most metabolic benefit from surgery. After this time rapid weight loss generally declines.
Rather than being a time to coast along, it is a crucial time to reset your diet, exercise, and mindset towards healthier habits. That way, when the honeymoon is over, as it invariably will be at some point, you’ve spent the time investing in a healthy lifestyle to support you for the long term.
Individual factors that influence weight loss after gastric sleeve
It is important to note, that not everyone loses weight like this after gastric sleeve. For some, it’s a slower process. One important thing I like to remind patients experiencing this, is that any weight loss is positive for your health and wellbeing.The amount of weight you lose with gastric sleeve surgery can vary depending on several individual factors. These include:
- Your starting weight. Generally, individuals with a higher initial weight tend to lose a greater amount of weight after the surgery. This is because they typically have more excess weight to lose. However, percentage-wise, those with a higher BMI may not experience as much overall percentage of weight loss.
- Age. Younger patients tend to experience more substantial weight loss compared to older individuals. Metabolism tends to be higher in younger people, contributing to increased calorie burning.
Overall health. Existing medical conditions, such as diabetes or hormonal imbalances, can affect the rate of weight loss.
- Lifestyle modification. Adhering to post-surgery dietary guidelines, exercise, and lifestyle changes can also influence outcomes.
Long term weight loss expectations
Beyond the initial weight loss phase, the rate of weight loss will usually stabilise. It is helpful to have realistic expectations for long-term weight loss after gastric sleeve surgery. While individual results may vary, patients can generally expect to maintain a weight loss of 50-60% of their excess body weight over the long term.
Other health benefits gastric sleeve may bring
Gastric sleeve surgery not only promotes weight loss but also offers significant health benefits. Many patients experience improvements in obesity-related health conditions, such as type 2 diabetes, high blood pressure, sleep apnoea, and joint pain. These positive outcomes are significant, and should be celebrated just as enthusiastically, (if not more so!) than anything the scales says.
Maximise health and weight loss after gastric sleeve
To maximize the benefits of gastric sleeve surgery and maintain weight loss over time, adopting healthy lifestyle changes is crucial. This includes following a well-balanced diet, engaging in regular physical activity, managing stress, and establishing a support system. It has been shown time and again, that a comprehensive post-operative follow-up program is one of the most important factors determining your success after bariatric surgery.
