Weight Loss and Comorbidity Outcomes After Revisional Bariatric Surgery
Sponsor: Kasr El Aini Hospital
Summary
Some people who have had weight-loss (bariatric) surgery do not lose enough weight, regain much of the weight they lost, see obesity-related diseases such as diabetes or high blood pressure return, or develop complications of the first operation. Many of them need a second, revisional operation. This study reviews the medical records of adults who had revisional bariatric surgery between 2017 and 2025 at a single surgical centre. It describes which revisional operations were performed after each type of first operation and measures how much weight patients lost 6 months, 12 months and up to 3 years after the revision. It also records whether obesity-related diseases and quality of life improved after the revision, and looks at patient factors linked to better weight loss.
