Question 1

Which lab value is most important to monitor for bone health in long-term bariatric surgery follow-up?

Accepted Answer

Calcium and vitamin D levels

Answer

Calcium and vitamin D deficiency are common after bariatric surgery, leading to metabolic bone disease and increased fracture risk if not monitored.

Question 2

What is the primary mechanism by which sleeve gastrectomy promotes weight loss?

Accepted Answer

Restriction of stomach volume and reduction of ghrelin

Answer

Sleeve gastrectomy removes about 80% of the stomach, reducing capacity and lowering ghrelin (hunger hormone) levels by removing the gastric fundus.

Question 3

Postoperative iron deficiency after bariatric surgery is MOST common in which patient population?

Accepted Answer

Premenopausal women

Answer

Premenopausal women are at highest risk for iron deficiency after bariatric surgery due to menstrual blood loss combined with reduced iron absorption.

Question 4

Which bariatric procedure carries the highest risk of nutritional deficiencies due to its extensive malabsorptive component?

Accepted Answer

Biliopancreatic diversion with duodenal switch (BPD/DS)

Answer

BPD/DS bypasses most of the small intestine, causing the most severe malabsorption and requiring the most intensive lifelong supplementation.

Question 5

What is 'pouch dilation' in the context of gastric bypass surgery?

Accepted Answer

Stretching of the small gastric pouch created during surgery

Answer

Pouch dilation occurs when the small gastric pouch stretches over time, usually due to overeating, reducing restriction and contributing to weight regain.
