Example Calculation
Patient Example
Profile: 35-year-old, 170 cm (5'6"), 131 kg (289 lbs), BMI 45.4
Ideal weight: 170 cm → 71.9 kg (158 lbs) at BMI 24.9
Excess weight: 131 - 71.9 = 59.1 kg (130 lbs)
Gastric sleeve expected loss: 59.1 × 0.70 = 41.4 kg (91 lbs)
Final projected weight: 131 - 41.4 = 89.6 kg (198 lbs)

Understanding Gastric Sleeve Surgery
What is Gastric Sleeve Surgery?
Gastric sleeve surgery (sleeve gastrectomy) involves removing approximately 80% of the stomach, leaving a banana-shaped "sleeve" that holds much less food. This procedure is irreversible but highly effective for significant weight loss.
How Weight Loss is Calculated
Expected Loss = Excess Weight × 0.70
Gastric sleeve typically results in 70% excess weight loss
- •Calculate ideal weight using BMI = 24.9
- •Subtract ideal weight from current weight
- •Multiply excess weight by 0.70 for expected loss
Benefits and Considerations
Benefits
- • Excellent long-term weight loss (70% excess weight)
- • No malabsorption issues
- • Improvement in diabetes and other conditions
- • Reduced hunger hormones
- • No foreign objects or adjustments needed
Considerations
- • Irreversible procedure
- • Potential for surgical complications
- • Requires significant lifestyle changes
- • Possible nutrient deficiencies
- • Risk of acid reflux
Important: These calculations provide estimates based on average outcomes. Individual results may vary significantly based on factors including age, starting weight, compliance with post-surgery guidelines, exercise habits, and underlying health conditions.
