After the duodenal switch, you will eat significantly smaller portions because your stomach will be much smaller. You’ll also need to focus on high-protein foods, eating multiple small meals throughout the day to ensure you get enough nutrients. Certain foods may be more difficult to tolerate, and you may need to avoid foods that are high in fat or sugar to prevent discomfort.

The malabsorptive component of the duodenal switch can lead to changes in digestion, including looser and more frequent bowel movements. Some patients experience steatorrhea (fatty stools) if they eat too much fat. It’s important to stay hydrated and maintain a balanced diet to minimize these effects.

Oftentimes, some patients find that they develop new food intolerances after surgery. Fatty, greasy, or sugary foods can cause discomfort or digestive issues. You may need to experiment with different foods to determine what your body tolerates best post-surgery.

Most patients begin losing weight rapidly within the first few weeks after surgery. Significant weight loss usually occurs within the first 12-18 months. The amount and speed of weight loss can vary depending on individual factors such as adherence to dietary guidelines, exercise, and overall health.

While the duodenal switch is highly effective at promoting long-term weight loss, some patients may experience weight regain if they do not adhere to the recommended diet and lifestyle changes. It’s essential to maintain a balanced, healthy diet and regular exercise to prevent regaining weight over time.
