Weight Loss Surgery Ultimate 4 — Questions and Answers
Question 1: Which of the following is a contraindication to bariatric surgery in most US centers?
- BMI of 40 with no comorbidities
- Uncontrolled severe psychiatric illness (Correct answer)
- Type 2 diabetes with BMI 35
- Age 55 with hypertension
Correct answer: Uncontrolled severe psychiatric illness
Uncontrolled severe psychiatric illness is a contraindication because patients must be able to adhere to lifelong behavioral and nutritional changes required after surgery.
Question 2: What is the minimum BMI typically required for bariatric surgery in the US when no obesity-related comorbidities are present?
- 30
- 35
- 40 (Correct answer)
- 45
Correct answer: 40
The standard threshold is BMI ≥40 without comorbidities, or BMI ≥35 with at least one obesity-related condition such as diabetes or sleep apnea.
Question 3: Which imaging study is commonly performed before bariatric surgery to evaluate the upper GI tract for ulcers or hiatal hernia?
- CT scan of the abdomen
- Esophagogastroduodenoscopy (EGD) (Correct answer)
- MRI of the pelvis
- Barium enema
Correct answer: Esophagogastroduodenoscopy (EGD)
EGD (upper endoscopy) is routinely performed pre-operatively to identify H. pylori infection, ulcers, or hiatal hernia that could complicate or be exacerbated by surgery.
Question 4: Which dietary change is MOST critical in the first 2 weeks after bariatric surgery?
- Following a high-fiber solid food diet
- Consuming only clear and full liquids (Correct answer)
- Eating small amounts of soft proteins
- Avoiding all carbohydrates permanently
Correct answer: Consuming only clear and full liquids
The immediate post-operative phase requires a liquid diet to allow healing of surgical connections and avoid stress on the new anatomy.
Question 5: What role does H. pylori play in pre-bariatric surgery evaluation?
- It has no relevance to bariatric outcomes
- It must be detected and eradicated to reduce risk of post-op ulcers (Correct answer)
- It improves weight loss after surgery
- It only matters for sleeve gastrectomy patients
Correct answer: It must be detected and eradicated to reduce risk of post-op ulcers
H. pylori infection increases risk of marginal ulcers post-surgery, so testing and eradication before the procedure is standard of care in most programs.
Question 6: What is 'marginal ulcer' in bariatric surgery patients?
- An ulcer at the skin incision site
- An ulcer at the gastrojejunal anastomosis in gastric bypass patients (Correct answer)
- A gastric ulcer caused by excessive acid
- A small bowel ulcer from NSAID use
Correct answer: An ulcer at the gastrojejunal anastomosis in gastric bypass patients
Marginal ulcers form at or near the connection between the gastric pouch and jejunum in bypass patients and are associated with NSAID use, smoking, and H. pylori.
Question 7: How long should bariatric surgery patients typically avoid NSAID medications (like ibuprofen) post-operatively?
- 2 weeks
- 3 months
- Indefinitely or as long as possible (Correct answer)
- Until they reach goal weight
Correct answer: Indefinitely or as long as possible
NSAIDs are generally contraindicated long-term after bariatric surgery because they significantly increase the risk of marginal ulcers in the reduced stomach pouch.
