Bariatric surgery involves making changes to your digestive system to aid your weight loss goal when all other options fail. You may be wondering how your diet should change once you have been through these procedures. When trying to understand what types of foods and fluids are good for your body post-surgery, one thing is for sure; not all beverages are created equal. When trying to figure out your new lifestyle post-surgery, it is important to avoid these three beverages.

Highly Caffeinated and Sugary Drinks

Highly Caffeinated and Sugary Drinks

All beverages that contain corn syrup, sugar, or fructose should be avoided post weight loss surgery. Consuming drinks that have lots of sugar like fruit juices and soda can lead to dumping syndrome or abdominal pain. These options can also lead to dehydration which is not ideal when recovering from surgery and adapting to having a smaller stomach. If you are thirsty, choose water, decaffeinated coffee, and tea, or unsweetened packaged drinks.


Alcoholic Beverages

Alcoholic Beverages definitely will not be recommended as part of your post-surgery lifestyle. Not only are they high in calories, but they also take up too much space in your stomach where foods packed with nutrients and vitamins should be instead. Additionally, alcohol absorption dramatically increases post-surgery, which will lead to extreme intoxication.

3 Beverages to Stay Away From After Bariatric SurgeryCarbonated Beverages

It is advised to avoid carbonated beverages for at least the first three months after surgery. Bubbly drinks can cause upset stomach, gas, nausea, and possibly damage to a newly healing stomach. However, every patient is different and some will be able to handle carbonated beverages shortly after surgery, while others might find that they need to go several months without it.



Patients are advised to drink plenty of water, approximately 8 classes per day. It is crucial to remember not to consume beverages 30 minutes before, after, or during your meals. This is important for any weight loss surgery plan and will help to feel full and save the space in your stomach for nutrients and vitamins.
