Weight Loss Weight Loss Surgery 2 — Questions and Answers
Question 1: Which bariatric procedure is considered fully reversible?
- Sleeve gastrectomy
- Roux-en-Y gastric bypass
- Adjustable gastric band (Correct answer)
- Biliopancreatic diversion
Correct answer: Adjustable gastric band
The adjustable gastric band (lap band) is the only commonly performed bariatric procedure that can be fully removed and does not permanently alter the stomach or intestines.
Question 2: What is the primary mechanism by which Roux-en-Y gastric bypass promotes weight loss?
- Restriction only
- Malabsorption only
- Both restriction and malabsorption (Correct answer)
- Hormonal suppression only
Correct answer: Both restriction and malabsorption
Gastric bypass promotes weight loss through both restriction (a smaller stomach pouch) and malabsorption (bypassing part of the small intestine), along with favorable hormonal changes.
Question 3: Which obesity-related comorbidity has the highest remission rate following bariatric surgery?
- Hypertension
- Type 2 diabetes (Correct answer)
- Sleep apnea
- Osteoarthritis
Correct answer: Type 2 diabetes
Type 2 diabetes has the highest remission rate after bariatric surgery, with 60–80% of patients achieving remission, often before significant weight loss occurs.
Question 4: Which hunger-stimulating hormone decreases significantly after sleeve gastrectomy, helping reduce appetite?
- Leptin
- Insulin
- Ghrelin (Correct answer)
- Cortisol
Correct answer: Ghrelin
Ghrelin, the primary hunger hormone, is produced mainly in the fundus of the stomach, which is removed during sleeve gastrectomy, resulting in substantially reduced hunger signals.
Question 5: What is the typical recommended minimum daily protein intake for bariatric surgery patients post-operatively?
- 20–30 grams
- 40–50 grams
- 60–80 grams (Correct answer)
- 120–150 grams
Correct answer: 60–80 grams
Most bariatric programs recommend 60–80 grams of protein daily to preserve muscle mass and support healing during rapid weight loss after surgery.
Question 6: Which long-term complication is specifically associated with Roux-en-Y gastric bypass due to the rerouting of intestines?
- Worsening acid reflux
- Internal hernias (Correct answer)
- Port site infections
- Band slippage
Correct answer: Internal hernias
Internal hernias are a serious long-term complication of gastric bypass that occur when bowel loops herniate through mesenteric defects created during the intestinal rerouting.
Question 7: What is the typical pre-operative weight loss goal required by many surgeons before bariatric surgery?
- 0–2% of body weight
- 5–10% of body weight (Correct answer)
- 15–20% of body weight
- 25–30% of body weight
Correct answer: 5–10% of body weight
Most surgeons require patients to lose 5–10% of their body weight pre-operatively to reduce the liver size, lower surgical risk, and improve operative access.
