Bariatric surgery is considered for patients with which weight criteria?

• A. BMI > 40
• B. BMI > 30 with cancer
• C. BMI > 40 or BMI > 35 with a serious complication, or BMI 30–34.9 with type 2 diabetes and poor glycemic control
• D. BMI < 25

Answer: (C)

Bariatric surgery eligibility is based on how severe the obesity is and what obesity-related health problems are present. The strongest indications are when BMI is very high, or when BMI is moderately high but accompanied by serious health issues that weight loss can improve. This set of criteria reflects that: BMI over 40 shows a high mortality and morbidity risk from obesity, so surgery is commonly considered. If BMI is over 35 but there are serious obesity-related complications, surgery is also appropriate because the health burden is substantial. Additionally, when BMI is in the 30s and type 2 diabetes has poor glycemic control, weight-loss surgery can markedly improve diabetes outcomes, so considering surgery in that group is reasonable. That combination explains why this option is the best answer: it encompasses the main weight thresholds plus the key comorbidity scenario (poorly controlled type 2 diabetes) that can justify surgical intervention in patients with BMI in the 30–34.9 range. The other patterns don’t align with standard indications—for example, having cancer or a BMI under 25 does not, by itself, justify bariatric surgery based on these criteria.
