Question 1: Which bariatric procedure involves creating a small stomach pouch and rerouting the small intestine?
- Gastric banding
- Gastric bypass (Correct answer)
- Sleeve gastrectomy

Correct answer: Gastric bypass
Gastric bypass surgery reduces stomach size and alters digestion by bypassing a portion of the small intestine, leading to weight loss.

- Malabsorption of nutrients
