Biliopancreatic diversion with duodenal switch (BPD/DS) is very similar to gastric bypass. Instead of a small stomach pouch, the surgeon creates a sleeve-shaped stomach. The surgeon then attaches the final section of the small intestine to the stomach sleeve. The small intestine absorbs calories and nutrients. So, bypassing all but the last section of the small intestine ensures that far fewer calories are absorbed.
Excess Weight Loss
BPD/DS patients typically lost 70.1 percent of their excess weight.
Studies found that BPD/DS:
- Resolved type 2 diabetes in 98.9% of patients
- Resolved high blood pressure in 75.1% of patients
- Improved high cholesterol in 99.1% of patients
- Resolved obstructive sleep apnea in 91.9% of patients
Quality of Life
One meta-analysis stated that for bariatric surgery patients who experienced significant weight loss:
- Overall quality of life improved greatly
- They experienced improved appearance and physical functioning
- They experienced improved social and economic opportunities
Potential Concerns of BPD/DS
- Abdominal bloating and foul-smelling stool or gas may occur.
- Patients also need to supplement with daily multivitamins and calcium and may be prescribed vitamin B12 and iron by their healthcare professional.
