Duodenal Switch

The Duodenal Switch procedure (DS, BPD/DS) reduces stomach size, reroutes the intestines, and removes the gallbladder.

Nutrient deficiencies may arise due to:

  • Significant malabsorption
  • Reduced stomach volume
  • Reduced dietary intake
  • Decreased capacity for digestion due to changes in stomach size
  • Reduced gastric acid (use of PPIs, and reduced volume)
