Condition	Prior Criteria (1991)	New 2022 Criteria
BMI threshold alone	≥ 40 kg/m²	≥ 35 kg/m²
BMI + Comorbidity	≥ 35 kg/m²	≥ 30 kg/m²

Practical Pearls

Paradigm Shift

The 2022 guidelines recognize metabolic surgery as a primary treatment for uncontrolled metabolic disease, not just mechanical weight loss. It is heavily prioritized for Type 2 Diabetes management regardless of extreme obesity.

Preoperative Clearance

Eligibility criteria is the starting point, not the clearance. Patients must undergo rigorous psychosocial, nutritional, and medical clearance. Active substance abuse, severe uncontrolled psychiatric illnesses, and inability to comply with lifelong supplements are contraindications.

Next Steps

Procedure Selection (Brief guide)

Sleeve Gastrectomy: Preferred for general severe obesity, least technical complications, but worse severe reflux (GERD) outcomes.
Roux-en-Y Gastric Bypass (RYGB): Gold standard for uncontrolled Type 2 Diabetes and severe GERD. Higher risk of malabsorption.
Biliopancreatic Diversion (BPD/DS): Greatest weight loss, reserved for extreme obesity (BMI >50), highest risk of profound malnutrition.
