What to Expect
You’ll see short-term results immediately, but the key is keeping the weight off in the long-term.
Your post-surgery weight loss is measured as Percent Excess Weight Loss (%EWL). Excess is defined as your actual weight minus your ideal body weight (IBW).
Calculating your Ideal Body Weight (IBW)
- 106 + 6 x (height in inches – 60) = IBW
- 106 + 6 x (72 – 60) = 178
- If you weigh 400 pounds, your excess weight is 222 lbs.
- If you lose 200 pounds, you’ve lost 55% of your excess weight (%EWL=55%)
- 100 + 5 x (height in inches – 60) = IBW
- 100 + 5 x (65 -60) = 125
- If you weigh 325 pounds, your excess weight is 200 lbs.
- If you lose 100 pounds, you’ve lost 50% of your excess weight (%EWL=50%)
On average, your %EWL after surgery can vary, but 90% of people will have lost between 95% and 60% of their excess weight at 2 years. It’s often easier for a patient who weighs 220 pounds to lose a higher percentage of excess weight that a person who weighs 300 or 600 pounds. On average, patients regain 10 – 15% of their excess weight back in the long run.
Sometimes, patients who lose a significant amount of weight opt for additional surgery to have excess skin removed. If you lose a lot of weight, you can see excess skin of 20 or more pounds. We recommend waiting 18 – 24 months before having this cosmetic surgery and can recommend plastic surgeons who are experienced with bariatric surgery patients and their needs.
