- Gastric Bypass
The duodenal switch (DS) combines restrictive and malabsorptive elements to achieve weight loss. It is usually reserved for patients who have a BMI of 70 or greater. The DS procedure includes a sleeve gastrectomy, which reduces the stomach size and rerouting of the small bowel. Unlike the gastric bypass, patients who have the DS procedure do not get dumping syndrome or marginal ulcers. Because the DS bypasses a much greater length of small bowel than the bypass, the DS carries a higher risk of malnutrition and vitamin deficiencies.
Advantages of duodenal switch surgery include:
• rapid weight loss (typical weight loss of 5+ pounds per week);
• reduced capacity to eat large volumes of food;
• no “dumping syndrome”, like can be seen in bypass patients;
• no adjustments, like are necessary with the gastric band;
• fewer follow-up appointments than with the gastric band;
• procedure is done laparoscopically (small incisions);
• proven success;
• typical recovery period of 1-2 weeks;
• reduction or resolution of serious co-morbidities such as type 2 diabetes, high blood pressure, sleep apnea, high cholesterol.
