Sleeve surgery in the UK refers to sleeve gastrectomy, one of the most popular weight-loss surgeries.

Roux-en-Y Gastric Bypass (RYGB) is a popular form of bariatric surgery that reduces the size of the stomach and reroutes the digestive system. This results in both restriction of food intake and malabsorption, leading to significant weight loss. The surgery is considered highly effective for morbidly obese individuals and also helps improve obesity-related health issues like diabetes, hypertension, and sleep apnea. However, it requires lifelong dietary changes and nutritional supplements to avoid deficiencies.

The altered bowel motility and absorption as a result of weight-loss surgery also can result in more or smellier gas. Noise associated with gas can be from the abdomen (bowel sounds) or with the passage of gas through the anus (or an ostomy).
