Post-gastric sleeve surgery can cause an uncomfortable sensation after just a few extra bites. Your stomach is much smaller, especially in the early recovery days. So, What Happens If You Eat Too Much After Gastric Sleeve Surgery?
While people preparing for bariatric surgery Turkey quickly look for information about the procedure itself, discovering how to experience the signals of fullness after surgery is vital as well. Here is how overeating might feel, what you can do immediately, and when medical help is necessary.
What Happens If You Eat Too Much After Gastric Sleeve?
Eating beyond your new stomach’s comfortable capacity can create pressure, pain, nausea or vomiting. You may also experience:
- Tightness in your upper abdomen or chest
- Acid reflux or regurgitation
- Bloating or repeated burping
- Hiccups or increased saliva
- A sensation that food is stuck
- Sudden fatigue or discomfort after eating
According to University College London Hospitals, vomiting after sleeve surgery can be a result of the following factors: eating too fast, drinking liquids near a meal, chewing food very little, and eating too much.
What Should You Do Immediately?
Stop eating when you are feeling pressure, pain or full. Try not to “stuff” the food down by drinking a lot at once, as extra fluid can overfill the stomach and make vomiting worse than normal.
Sit up straight, slowly walk around if comfortable and allow your tummy to settle. After dealing with the pain, you should go back to eating the level of foods and food sizes your bariatric team recommends.
For future meals:
- Use a small plate
- Take thumbnail-sized bites
- Chew each bite thoroughly
- Allow 20–30 minutes for the meal
- Stop when comfortably satisfied, not completely full
- Keep drinks separate from meals
This will help to minimize discomfort and facilitate the passing of food through the sleeve.
