Introduction
Endoscopic Sleeve Gastroplasty (ESG) is changing the way people approach weight loss. It’s minimally invasive, incision-free, and often leads to impressive ESG weight loss results. But what can you realistically expect?
This article breaks down ESG weight loss results—from the first few weeks to long-term outcomes. Whether you’re considering the procedure or preparing for it, this guide will help set the right expectations.
What Is ESG?
ESG stands for Endoscopic Sleeve Gastroplasty. It’s a non-surgical weight loss procedure performed using an endoscope inserted through the mouth.
The endoscope allows the doctor to reduce the stomach’s size by placing internal sutures. This creates a smaller, tube-shaped stomach without cutting or removing tissue.
The smaller stomach limits food intake and slows digestion. As a result, you feel full sooner and eat less. ESG does not involve external incisions, which makes recovery much faster.
How ESG Promotes Weight Loss
Unlike diet changes alone, ESG modifies the structure of your stomach. This has a direct effect on how much food you can eat. With a reduced stomach size, your hunger hormones also shift. Many patients report feeling full longer, even with smaller meals. When combined with a medical weight loss program, the benefits multiply. Nutrition guidance, behavior coaching, and regular check-ins help reinforce success.
Average Weight Loss After ESG
Let’s get into the numbers. What are the real ESG weight loss results you can expect?
In the first 1 to 3 months, patients often lose 10 to 15% of their total body weight.
By month 6, many reach 15 to 20% total body weight loss.
After 12 months, the average weight loss is 18 to 20%, sometimes more.
These numbers reflect results from real studies and clinical trials. They can vary based on your age, habits, and baseline weight.
Percent of Excess Weight Lost
Doctors often measure success using “excess weight loss” (EWL). This refers to how much weight you lose compared to how much you need to lose.
On average:
Patients lose 50 to 60% of their excess weight in the first year.
With good habits, some reach 65% or more within 18 months.
For example, if you’re 100 pounds overweight, you might lose 50 to 60 pounds in the first year after ESG.
Factors That Affect ESG Outcomes
Not everyone sees the same endoscopic sleeve weight loss results. Several personal factors play a role in how effective the procedure will be. Your commitment to lifestyle changes such as diet and physical activity is just as important as the ESG itself. Age and metabolism also matter—patients who are younger often lose weight faster. Underlying medical conditions, like thyroid disorders, can make the process slower or more complex. A strong support system, whether through professional coaching or peer groups, can significantly improve long-term outcomes. The procedure is powerful, but it is not magic. Your active participation is essential for lasting success.
What to Expect in the First Few Months
During the first month after the ESG procedure, your body adjusts to a smaller stomach size. This stage brings rapid changes. Most patients begin with a liquid diet and then progress to soft foods. You’ll eat much less than before, and your appetite will likely decrease. In the first four to six weeks, you may lose 5 to 10% of your total body weight. Some people lose more, especially if they follow all dietary recommendations. Energy levels may fluctuate during this phase. Short walks and hydration help manage fatigue. Your care team will guide you step by step.
Milestones at 3 and 6 Months
At three months, weight loss tends to accelerate. You’ve likely transitioned to solid foods and built new habits around portion control. Many people notice improvements in sleep, mobility, and energy. Clothes fit better. Blood pressure and cholesterol may begin to drop.
By six months, your ESG weight loss results should be visible and measurable. It’s common to have lost 15 to 20% of your total body weight by now. This period is critical. Patients who stay consistent with their nutrition and activity see the best outcomes. Those who slip into old habits may see slower progress.
One Year After ESG: What the Data Shows
Twelve months after the procedure, the average patient reaches 18 to 20% total body weight loss. That often translates to 50 to 60% of excess weight lost.
In addition to physical changes, emotional transformation is common. Confidence grows. You may feel more in control of your health.
At this point, ESG outcomes depend on your long-term routine. Following up with your medical team and continuing healthy habits is essential.
For many, the one-year mark feels like a turning point. It’s not just about losing weight, it’s about gaining a new lifestyle.
What ESG Will Not Do
While ESG is effective, it’s still important to understand its limits. After all, the procedure is a tool, not a cure. Furthermore, ESG won’t fix emotional eating or body image struggles on its own. It also doesn’t guarantee instant confidence or perfect health. However, you still need to show up for yourself. That means consistently choosing nourishing foods, staying active, and seeking mental health support when needed. Ultimately, success comes from using ESG as part of a larger wellness plan, not depending on it as the only solution.
Who Gets the Best Results After ESG?
Patients who thrive after ESG usually have a few things in common. Patients who thrive after ESG usually have a few things in common. They engage actively in their care and follow up regularly with their doctor. To stay on track, many use tools like food logs, support groups, and fitness trackers. Instead of waiting for motivation, they create it through structure and routine. While they understand setbacks will happen, they keep going anyway. Weight loss from ESG is a journey. The more tools you use, the more supported you’ll feel.
