Question 1

Which bariatric procedure is considered fully reversible?

Accepted Answer

Adjustable gastric band

Answer

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?

Accepted Answer

Both restriction and malabsorption

Answer

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?

Accepted Answer

Type 2 diabetes

Answer

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?

Accepted Answer

Ghrelin

Answer

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?

Accepted Answer

60–80 grams

Answer

Most bariatric programs recommend 60–80 grams of protein daily to preserve muscle mass and support healing during rapid weight loss after surgery.
