For Albertans living with obesity who don't qualify for traditional bariatric surgery or simply don't want it there is now a new option in Edmonton.
The Royal Alexandra Hospital began offering endoscopic sleeve gastroplasty in December and announced the program publicly on Wednesday. It is the only facility in Alberta performing the procedure. Eight patients have had it done.
What it actually does
An endoscope a flexible tube fitted with a camera and suturing tools goes in through the mouth. No cuts are made anywhere on the body. The surgeon places sutures along the inside of the stomach wall, pulling them tight to fold and reduce the stomach's volume by roughly 70%. The stomach isn't surgically removed it's reshaped internally, like sewing a dart into fabric.
The result is a smaller stomach that fills faster. Patients feel full with less food. They go home the same day or the next morning.
The procedure targets more than weight. Reducing stomach size has been shown to improve or resolve obesity-related conditions including type 2 diabetes, high blood pressure, and sleep apnea the same downstream effects seen with traditional bariatric surgery, reached through a significantly less invasive route.
Why this matters for Alberta specifically
Alberta's bariatric surgery system has a capacity problem. As of 2023, roughly 950 Albertans were on a waitlist for bariatric procedures, with the majority in the Edmonton zone. An Edmonton obesity specialist described the timeline plainly: from the time a family doctor makes a referral, patients typically wait at least three years before surgery. Sometimes longer.
AHS operates five bariatric specialty clinics across the province in Edmonton, Calgary, Red Deer, Grande Prairie, and Medicine Hat. Demand has consistently outpaced what the system can deliver. Some patients have seen diabetes, sleep apnea, and high blood pressure worsen while waiting. Others develop new conditions that complicate their surgical eligibility by the time their name comes up.
Endoscopic sleeve gastroplasty doesn't require the same surgical infrastructure. It's performed endoscopically no operating room bed, no general surgical team, no multi-week recovery. For patients who fall outside surgical eligibility, or who have been waiting years and can't wait longer, it now exists as an option at one Alberta hospital.
Where it fits in the treatment landscape
Between lifestyle change and full bariatric surgery, there isn't much. GLP-1 medications like Ozempic and Wegovy have filled some of that gap they work for many patients but are expensive, require long-term use to maintain results, and don't suit everyone. Bariatric surgery works but carries real risks, requires removing a permanent portion of the stomach, and has a multi-year waitlist in Alberta.
Endoscopic sleeve gastroplasty sits between them. The complication rate is under two percent based on published clinical data. The procedure is potentially reversible. The American Society for Metabolic and Bariatric Surgery added it to its list of endorsed procedures in 2026.
"Especially for patients who don't qualify for traditional bariatric surgery or prefer a less invasive option," said Dr. Noah Switzer, an upper gastrointestinal and bariatric surgeon at the Royal Alex. "Rather than having a complex surgery requiring extensive recovery, patients have access to technology that requires no cuts or incisions that allows them to go home the same or next day."
One patient's experience
Mary-Ann Thurber, 65, had the procedure done in February two months after the program launched.
"I am sleeping better, I have more energy and ultimately feel better equipped and motivated to manage my weight without the help of appetite suppression medication," she said.
Clinical studies have reported average total body weight loss of roughly 15 to 17 percent after 12 months, with improvement or remission of obesity-related conditions in a significant proportion of patients.
How to access it
The procedure is available through the Royal Alexandra Hospital's Adult Bariatric Surgery Clinic by physician referral. Speak with a family doctor about a referral to the RAH bariatric program.
The Royal Alexandra Hospital is at 10240 Kingsway Avenue NW, Edmonton.
