Weight Loss Surgery Considering Weight Loss Surgery 4 — Questions and Answers
Question 1: Which of the following patients would most likely be considered a high surgical risk for bariatric surgery?
- A patient with severe pulmonary hypertension and NYHA Class IV heart failure (Correct answer)
- A 45-year-old with controlled hypertension
- A 38-year-old with well-managed type 2 diabetes
- A patient with obstructive sleep apnea using CPAP
Correct answer: A patient with severe pulmonary hypertension and NYHA Class IV heart failure
Severe pulmonary hypertension with advanced heart failure significantly increases anesthesia and surgical mortality risk.
Question 2: Why is calcium citrate preferred over calcium carbonate for bariatric patients post-surgery?
- Calcium citrate does not require stomach acid for absorption (Correct answer)
- Calcium citrate has fewer calories
- Calcium carbonate causes kidney stones exclusively in bariatric patients
- Calcium citrate is cheaper
Correct answer: Calcium citrate does not require stomach acid for absorption
After surgery, reduced stomach acid production means calcium carbonate cannot dissolve properly, while calcium citrate absorbs without acid.
Question 3: What is the most common reason patients are denied bariatric surgery after completing the evaluation process?
- Failure to comply with pre-operative requirements or unresolved psychiatric concerns (Correct answer)
- Being too physically fit
- Refusing anesthesia consultation
- Not wanting a specific procedure type
Correct answer: Failure to comply with pre-operative requirements or unresolved psychiatric concerns
Non-compliance with pre-op milestones (diet, appointments, smoking cessation) and unaddressed mental health issues are leading reasons for denial.
Question 4: Which of the following best describes 'weight regain' after bariatric surgery?
- Re-accumulation of lost weight due to dietary non-compliance, pouch stretching, or hormonal changes (Correct answer)
- Normal fluctuation of 1–2 lbs daily
- Immediate post-op fluid retention only
- Muscle mass gained from post-op exercise programs
Correct answer: Re-accumulation of lost weight due to dietary non-compliance, pouch stretching, or hormonal changes
Long-term weight regain is multifactorial, involving behavioral, anatomical, and hormonal factors that can undermine initial success.
Question 5: A patient considering bariatric surgery has a BMI of 32 with type 2 diabetes poorly controlled on three medications. What is their eligibility status under emerging guidelines?
- Potentially eligible; newer ASMBS/IFSO guidelines lower the threshold to BMI ≥ 30 with metabolic disease (Correct answer)
- Not eligible; BMI must be ≥ 40 regardless of comorbidities
- Eligible only if they are under age 40
- Eligible only for lap band, not sleeve or bypass
Correct answer: Potentially eligible; newer ASMBS/IFSO guidelines lower the threshold to BMI ≥ 30 with metabolic disease
Updated 2022 ASMBS/IFSO guidelines extended eligibility to BMI ≥ 30 with uncontrolled metabolic conditions like type 2 diabetes.
Question 6: Which behavioral change is considered most predictive of long-term bariatric surgery success?
- Consistent attendance at post-operative support groups and follow-up appointments (Correct answer)
- Achieving maximum weight loss in the first 3 months
- Avoiding all carbohydrates permanently
- Returning to normal diet within 6 months of surgery
Correct answer: Consistent attendance at post-operative support groups and follow-up appointments
Long-term engagement with support groups and follow-up care is one of the strongest predictors of sustained weight loss success.
Question 7: What is the typical expected excess weight loss (EWL) for gastric sleeve surgery at two years post-operation?
- 50–70% of excess body weight (Correct answer)
- 10–20% of excess body weight
- 90–100% of excess body weight
- 25–35% of total body weight
Correct answer: 50–70% of excess body weight
Gastric sleeve patients typically lose 50–70% of excess body weight within the first two years.
