Understanding your options
Choosing a bariatric procedure is a personal decision. This guide explains what the operation involves and the factors your surgical team may consider.
How the procedure works
Approximately 75–80% of the stomach is removed, creating a narrower tubular stomach. The pylorus remains intact and food continues along the usual intestinal route. The procedure changes stomach capacity and hunger-related physiology.
Who is this procedure best suited for?
Sleeve gastrectomy may be appropriate for patients who want effective surgical weight loss without an intestinal bypass, particularly if they do not have significant pre-existing gastroesophageal reflux. Diabetes severity, BMI, prior operations and nutritional considerations also influence selection.
Potential benefits
Sleeve gastrectomy provides substantial weight loss and may improve type 2 diabetes, sleep apnea and other obesity-related conditions. There is no intestinal anastomosis or intentional small-bowel bypass.
Risks and important considerations
Risks include bleeding, staple-line leak, stricture, nutritional deficiencies, and new or worsening acid reflux. It is irreversible because part of the stomach is removed. Severe GERD or Barrett’s esophagus can make other operations preferable.
Recovery and follow-up
Surgery is generally laparoscopic. Recovery involves progressive diet stages, protein and fluid targets, vitamin supplementation, and ongoing multidisciplinary follow-up. The exact return-to-activity timeline varies.
What does the evidence show?
Long-term weight loss and metabolic improvement are well established, although individual results vary. Reflux is a particularly important factor when comparing sleeve with gastric bypass.

The right procedure depends on much more than BMI alone. A consultation can help clarify which treatment fits your needs and priorities.
