Gastric Bypass
Gastric bypass, also known as Roux-en-Y gastric bypass (RYGB) is the most common form of bariatric surgery performed where the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch and then the small intestine is rearranged to connect to both.
Nutrient deficiencies may arise due to:
- Reduced dietary intake
- Decreased capacity for digestion due to changes in stomach size
- Micronutrient absorption impaired due to bypassing sections where absorption predominantly occurs
