People who have gastric bypass surgery are at risk for:
- Pouch stretching. The stomach gets bigger over time.
- Breakdown of staple lines. The staples fall apart.
- Nutritional, vitamin, and mineral deficiencies. Your body will be less able to get nutrients from food.
- Stomal stenosis. A narrowing forms at the connection of the stomach and small intestine causing nausea, vomiting, reflux, and then an inability to eat.
- Gallstones. Quick weight loss can make you more likely to get these.
