Weight Loss Surgery Ultimate 2 — Questions and Answers
Question 1: Which vitamin deficiency is MOST commonly seen after Roux-en-Y gastric bypass due to reduced absorption in the bypassed duodenum?
- Vitamin C
- Vitamin B12 (Correct answer)
- Vitamin K
- Vitamin E
Correct answer: Vitamin B12
Vitamin B12 deficiency is very common after gastric bypass because intrinsic factor production is reduced and the primary absorption site (terminal ileum via duodenum) is bypassed.
Question 2: A patient 18 months post-sleeve gastrectomy reports severe heartburn and regurgitation. What is the most likely complication?
- Anastomotic leak
- Gastroesophageal reflux disease (GERD) (Correct answer)
- Dumping syndrome
- Band slippage
Correct answer: Gastroesophageal reflux disease (GERD)
GERD is a well-known complication of sleeve gastrectomy due to removal of the gastric fundus and increased intragastric pressure.
Question 3: What is the recommended minimum daily protein intake for bariatric surgery patients in the long-term maintenance phase?
- 30–40 grams
- 50–60 grams
- 60–80 grams (Correct answer)
- 100–120 grams
Correct answer: 60–80 grams
Most bariatric programs recommend 60–80 grams of protein daily long-term to preserve lean muscle mass and support healing.
Question 4: Which bariatric procedure has the highest rate of long-term remission for type 2 diabetes?
- Adjustable gastric band
- Sleeve gastrectomy
- Roux-en-Y gastric bypass (Correct answer)
- Intragastric balloon
Correct answer: Roux-en-Y gastric bypass
Roux-en-Y gastric bypass achieves the highest rates of type 2 diabetes remission, often before significant weight loss occurs, due to hormonal changes.
Question 5: What does 'dumping syndrome' refer to after bariatric surgery?
- Vomiting large food portions
- Rapid gastric emptying causing nausea, sweating, and diarrhea (Correct answer)
- Acid reflux into the esophagus
- Inability to absorb fat-soluble vitamins
Correct answer: Rapid gastric emptying causing nausea, sweating, and diarrhea
Dumping syndrome occurs when food moves too quickly from the stomach into the small intestine, triggering osmotic and hormonal responses causing GI and vasomotor symptoms.
Question 6: Which of the following is the LEAST restrictive weight loss surgery option?
- Roux-en-Y gastric bypass
- Biliopancreatic diversion with duodenal switch
- Adjustable gastric band (Correct answer)
- Sleeve gastrectomy
Correct answer: Adjustable gastric band
The adjustable gastric band is the least invasive and least restrictive option, with no bowel rerouting and an adjustable mechanism.
Question 7: A patient plans to become pregnant after gastric bypass. What is the generally recommended waiting period post-surgery?
- 3 months
- 6 months
- 12–18 months (Correct answer)
- 24–36 months
Correct answer: 12–18 months
Most guidelines recommend waiting 12–18 months after bariatric surgery before becoming pregnant to allow weight stabilization and nutritional status optimization.
