What are the most common risks of gastric bypass surgery?

The most common risks of gastric bypass surgery include:

1. Leakage: The most serious risk of gastric bypass surgery is leakage from the newly created connection between the stomach and the small intestine. This can lead to infection and other complications.

2. Blood clots: Gastric bypass surgery can increase the risk of blood clots in the legs and lungs.

3. Infection: Gastric bypass surgery is a major surgery and carries the risk of infection.

4. Nausea and vomiting: Many people experience nausea and vomiting after gastric bypass surgery. This is usually temporary, but can sometimes be severe and require hospitalization.

5. Nutritional deficiencies: Gastric bypass surgery can lead to nutritional deficiencies, such as vitamin B12 and iron deficiency. It is important to take supplements and eat a healthy diet to prevent these deficiencies.

6. Weight gain: Some people who have gastric bypass surgery regain weight over time. This can be due to a variety of factors, including not following a healthy diet and exercise plan, or stretching of the stomach pouch.

7. Hernias: Hernias can develop after gastric bypass surgery due to the increased pressure in the abdomen.

8. Dumping syndrome: Dumping syndrome is a condition that can develop after gastric bypass surgery. It occurs when food is dumped from the stomach into the small intestine too quickly, causing symptoms such as nausea, vomiting, and diarrhea.

9. Hypoglycemia: Hypoglycemia, or low blood sugar, can occur after gastric bypass surgery. This is because the stomach can no longer store and release sugar into the bloodstream as it did before surgery.

10. Death: Gastric bypass surgery is a major surgery and there is a small risk of death associated with the procedure.
