A Calculator Built by a Surgeon Who’s Had the Surgery Himself

Most weight loss calculators online are marketing gimmicks. We built ours to be honest. It gives you a realistic estimate grounded in clinical research, so you can make an informed decision about whether the sleeve is right for you.

But what makes Dr. Gmora truly different isn’t the number of surgeries. It’s the fact that he chose this surgery for himself. He knows what it feels like to struggle with weight, to try everything, and to finally find something that works.

“If dieting was the answer, you’d have solved this years ago. It was never about willpower. It was about your body fighting you every step of the way.”

Dr. Scott Gmora, MD, FRCSC

That personal experience shaped everything about The Sleeve Clinic — from the 15-person care team to the 5-year aftercare program that comes included with every surgery.

How Does Gastric Sleeve Work?

A quick overview of the procedure that’s helped thousands of patients transform their lives.

1

The Procedure

A minimally invasive, laparoscopic surgery that reduces your stomach to about 20% of its original size. Most patients go home the next day.

2

How It Helps

Your smaller stomach dramatically reduces hunger hormones (ghrelin), cravings, and your capacity to overeat. The biology changes — not just the willpower equation.

3

Long-Term Results

Patients typically lose 25–35% of their total body weight within 12–18 months. Our 5-year aftercare program helps you keep it off.

Questions About Weight Loss Surgery

Our calculator is based on published clinical research on gastric sleeve outcomes. No calculator can predict your exact results, and every person's journey is different, but the estimates we provide reflect what most patients can realistically expect.
Gastric sleeve surgery removes approximately 80% of the stomach, creating a smaller, banana-shaped stomach. This limits how much food you can eat at once and dramatically reduces the hunger hormone ghrelin. Most patients describe it as the food noise finally going quiet. The surgery is minimally invasive (laparoscopic), takes about 60–90 minutes, and most patients go home the next day.
Gastric sleeve is one of the most commonly performed bariatric procedures in the world. The complication rate is very low — lower than a gallbladder removal or hip replacement. Dr. Gmora has performed over 4,800 procedures and is a senior staff surgeon at St. Joseph's Healthcare Hamilton. He also teaches surgical technique to the next generation of bariatric surgeons at McMaster University.
Every patient at The Sleeve Clinic receives 5 years of included aftercare at no additional cost. That means regular check-ins with our team of 13+ care professionals, including 4 dietitians and your surgical team. We don't just operate and wish you well. We stay in your corner for years because lasting weight loss requires lasting support.
