Treatment Options for Severe Obesity with Large Abdominal Pannus

Initial Assessment and Non-Surgical Management

The American Gastroenterological Association recommends medical evaluation to determine BMI, waist circumference, and identify obesity-related health risks and complications for patients with a large abdominal pannus 1, 2
For patients with BMI ≥30 kg/m² or BMI ≥27 kg/m² with weight-related complications, a structured weight loss program should be initiated, as recommended by the Obesity Society 3, 4
Dietary intervention with caloric deficit of 500-1000 kcal/day, aiming for 1-2 pounds weight loss per week, is a core component of non-surgical management, according to the Gastroenterological Association 1, 5
Behavioral modification therapy to support lifestyle changes is recommended by the Obesity Society 3
Pharmacotherapy should be considered as an adjunct to lifestyle interventions when lifestyle changes alone are insufficient, with medications approved for long-term weight management including orlistat, naltrexone/bupropion, liraglutide, as stated by the Obesity Society and Current Obesity Reports 3, 6
Pharmacotherapy should only be continued if at least 5% of initial body weight is lost during the first 3 months, as recommended by the Obesity Society 3

Bariatric surgery is the most effective treatment for severe obesity and should be considered when BMI ≥40 kg/m² regardless of previous conservative interventions, or BMI ≥35 kg/m² with weight-related complications after failed non-surgical interventions, or BMI 30-34.9 kg/m² with metabolic disease, as recommended by the Obesity Society and JAMA 3, 4, 7
Common bariatric surgical procedures include laparoscopic sleeve gastrectomy (LSG) and Roux-en-Y gastric bypass (RYGB), with expected weight loss of approximately 25% after LSG and 30% after RYGB at 12 months, according to JAMA 7
The expected weight loss after bariatric surgery is approximately 25% after LSG and 30% after RYGB at 12 months, as reported by JAMA 7

Long-term multidisciplinary follow-up care is essential after bariatric surgery, typically for at least 2 years, as recommended by the Obesity Society 3, 4
Regular monitoring should include dietetic and micronutrient assessment, individualized nutritional supplementation, and psychological support, according to the Obesity Society and Gastroenterological Association 3, 4, 5

Bariatric surgery complications may include anastomotic leaks, stenosis, bleeding, and venous thromboembolism, as reported by JAMA 7
