Soda

Overall, soda should be avoided after bariatric surgery due to its negative effects on the digestive system and its lack of nutritional value. Patients should instead focus on consuming water and other low-sugar, low-calorie beverages to stay hydrated and support their weight loss goals.
Here are some of the problems with soda after bariatric surgery:
- Carbonation: Soda is carbonated, which means it contains carbon dioxide gas. This gas can cause discomfort, bloating, and even pain in patients who have undergone bariatric surgery. The gas can also cause the stomach pouch to expand.
- High sugar content: Many sodas are high in sugar, which can cause rapid spikes in blood sugar levels. The rapid delivery of high sugar content into the small intestine can cause dumping syndrome.
- Empty calories: Soda contains empty calories, which means that it provides no nutritional value. After bariatric surgery, patients need to focus on consuming nutrient-dense foods to ensure they are getting the nutrients they need without consuming excess calories.
- Dehydration: Soda can be dehydrating, which can be especially dangerous for bariatric surgery patients, as they are at a higher risk of dehydration due to the reduced capacity of their stomachs. Dehydration can lead to a range of health problems, including kidney stones, urinary tract infections, and constipation.
