How to Read the Chart: Understanding “Excess Body Weight Loss”
Before we show you a ar, it’s essential to understand the most important term we use: “Percentage of Excess Body Weight” (%EBW). This is the medical standard for measuring success after bariatric surgery, as it is personalized to you.
Why do we use it? A 50-pound (22.6 kg) weight loss is very different for a person who weighs 200 pounds versus a person who weighs 400 pounds. Using %EBW makes the data fair and accurate for everyone. Here’s the simple calculation:
- 1. Find Your Ideal Body Weight: This is the weight considered healthy for your height (a BMI of about 25).
- 2. Find Your Excess Body Weight: This is the weight you need to lose.
(Your Current Weight) – (Your Ideal Body Weight) = Your Excess Body Weight (EBW)
Example: If your current weight is 250 pounds (113 kg) and your ideal weight is 150 pounds (68 kg), your excess body weight is 100 pounds (45 kg). All the percentages in the gastric sleeve average weight loss chart refer to this 100-pound number. So, a 60% EBW loss would mean a 60-pound weight loss for this patient. On average, patients can expect to lose 60-70% of their excess body weight with gastric sleeve surgery.
How much weight can I lose with a gastric sleeve?
On average, patients who are committed to the post-surgery diet and lifestyle can expect to lose 60% to 70% of their excess body weight. The majority of this weight loss occurs within the first 12 to 18 months after the gastric sleeve surgery.

Gastric Sleeve Average Weight Loss Chart & Timeline
The gastric sleeve weight loss rate is not a straight line. It is fastest at the beginning and then gradually slows as you get closer to your goal. This initial “honeymoon phase” is when the surgery’s restriction and hormonal effects (less hunger) are strongest.
Below is a typical gastric sleeve average weight loss chart, showing the *percentage of excess body weight* you can expect to lose over time.
| Timeframe After Surgery | Average Percentage of Excess Weight Lost |
|---|---|
| 1-2 Weeks | 5% – 10% (This includes rapid water loss) |
| 1 Month | 15% – 25% |
| 3 Months | 30% – 40% |
| 6 Months | 45% – 55% |
| 12 Months (1 Year) | 55% – 70% |
| 18-24 Months | 60% – 70%+ (Typically final weight) |
As this weight loss chart shows, the journey is a process. The first 3-6 months are when you will see the most dramatic changes on the scale. After the 6-month mark, your average weight loss per month will slow down. This is normal and expected! This is when your new, healthy habits—like regular exercise and mindful eating—are most important. It is also common to hit “weight loss stalls” (periods of no loss for days or weeks). Trust the process, as this is a normal part of your body’s adjustment.
What is the average weight loss per month with gastric sleeve?
The average weight loss per month with gastric sleeve is fastest in the first 3-6 months, often ranging from 8 to 16 pounds (4-8 kg) per month. This rate will gradually slow down as you get closer to your ideal weight and your body’s metabolism adjusts.

Frequently Asked Questions (FAQ) About Gastric Sleeve Weight Loss
Q: What is gastric sleeve surgery?
A: Gastric sleeve surgery is a weight loss operation where the size of the stomach is reduced by about 75-80%. This new, smaller “sleeve” helps patients eat less and reduces hunger hormones, allowing them to lose weight more effectively.
Q: What is the fastest weight loss period after a gastric sleeve?
A: The “honeymoon period,” or the fastest weight loss rate, is during the first 3 to 6 months after your gastric sleeve surgery. This is when the surgery’s restriction and hormonal effects are at their peak.
Q: What is a “weight loss stall” and is it normal?
A: A weight loss stall is a period of days or weeks where the scale does not move. This is 100% normal and expected. It is a sign your body is adjusting its “set point.” The best way to beat a stall is to trust the process, focus on protein, stay hydrated, and increase your activity.
Q: How much weight will I lose in the first week?
A: A weight loss stall is a period of days or weeks where the scale does not move. This is 100% normal and expected. It is a sign your body is adjusting its “set point.” The best way to beat a stall is to trust the process, focus on protein, stay hydrated, and increase your activity.
Q: What is the average 3-month weight loss from the chart?
A: As the gastric sleeve average weight loss chart shows, many patients have lost 30% to 40% of their excess body weight by the 3-month mark. For a person with 100 pounds of excess weight, this would be 30-40 pounds.
Q: What factors affect my personal weight loss speed?
A: Your personal gastric sleeve weight loss rate depends on many factors, including your starting weight (BMI), age, gender, overall health, and—most importantly—your strict adherence to the post-operative diet and exercise guidelines.
Q: Will I regain the weight after my weight loss rate slows down?
A: The gastric sleeve surgery is a powerful tool, not a magic cure. It is possible to regain weight if you fall back into old habits, such as “grazing” (eating small amounts all day) or drinking high-calorie liquids. Your long-term success depends on using the tool with a permanently changed, healthy lifestyle.
Q: Can I lose weight *too* fast?
A: The weight loss is designed to be rapid, but your surgical team will monitor you. This rapid loss is why taking your prescribed vitamins and minerals is essential to prevent nutritional deficiencies and side effects like temporary hair loss.
