Burping, also known as belching, is a common experience after sleeve gastrectomy. While it can be surprising at first, this is a normal part of recovery for many patients. In this article, we explain why burping happens after a gastric sleeve, how long it typically lasts, and what you can do to manage it effectively.
If you're also experiencing reflux, discomfort, or bloating, see our related article on Reflux After Sleeve Gastrectomy or speak with our dietitian about helpful strategies.
Understanding the New Stomach Anatomy
During sleeve gastrectomy, approximately 80 percent of the stomach is removed, including the upper portion called the fundus. The fundus normally stretches to hold swallowed air. Without it, the new stomach is shaped like a narrow tube and holds much less volume. It also becomes stiffer in the early months after surgery.
Because the stomach is now smaller and less expandable, even small amounts of swallowed air can cause pressure. This often leads to increased burping, especially after meals or drinks.
What Is Burping?
Burping is a natural way for the body to release air that has been swallowed. This air enters the stomach during normal activities like eating, drinking, and talking. When too much air builds up, the top of the stomach stretches. This triggers a brief relaxation of the valve between the oesophagus and the stomach, allowing air to escape as a burp.
There are two main types of burping:
- Gastric burping: Air is released from the stomach. This is the most common type and may increase after sleeve gastrectomy.
- Supragastric burping: Air is drawn into the oesophagus and expelled without ever reaching the stomach. This is usually a behavioural habit and is not caused by the operation.
Why Do I Burp More After Sleeve Gastrectomy?
After surgery, the stomach is smaller and less stretchy. Although patients eat less food, they often swallow the same amount of air. Because there is less space to hold this air, it builds pressure quickly, causing more frequent burping.
In the first few months, the stomach is also healing and can feel tight. This makes burping even more noticeable.
Some patients also notice reflux or heartburn along with burping. This is caused by increased pressure in the sleeve stomach and changes in the function of the oesophageal valve. These symptoms usually improve as the stomach becomes softer and more flexible over time.
How to Reduce Burping After Sleeve Gastrectomy
💡 Quick Tips to Reduce Burping
- Eat slowly and chew your food well.
- Avoid talking while eating to reduce the amount of swallowed air.
- Do not drink during meals. Wait at least 30 minutes after eating before having fluids.
- Avoid fizzy or carbonated drinks. These introduce extra gas into the stomach.
- Do not chew gum. It causes you to swallow more air.
- Try peppermint tea after meals. Some patients find it helpful for bloating and gas.
- Be patient. Burping usually improves within 3 to 6 months as your stomach heals.
Extra Tips for Supragastric Burping
If your burping is constant, seems unrelated to meals, or occurs more when you're anxious or distracted, it may be caused by supragastric burping. This is a behavioural pattern that is not caused by the surgery.
To manage it, try the following strategies:
- Practice deep breathing or relaxation exercises.
- Use distraction techniques like walking or focusing on something else.
- Talk to a psychologist if the habit is persistent or affecting your quality of life.
When Should I Be Concerned About Burping?
Most burping after sleeve gastrectomy is harmless and temporary. However, you should speak to us or our dietitian if you notice:
- Frequent burping with acid reflux, regurgitation, or heartburn
- A sour or bitter taste in your mouth
- Difficulty swallowing or food getting stuck in your chest
- Persistent bloating, nausea, or upper abdominal discomfort
We can guide you on whether medication or further testing is needed.
Frequently Asked Questions (FAQs)
Is burping normal after a gastric sleeve?
Yes. Burping is common after sleeve gastrectomy, especially in the first few months. It usually improves as your stomach becomes more flexible.
How long does burping last after sleeve gastrectomy?
Most patients notice improvement by 3 to 6 months after surgery. The body adapts over time, and burping becomes less frequent.
What foods or drinks make burping worse?
Fizzy drinks, chewing gum, and eating too quickly are common triggers. Drinking fluids with meals can also make burping worse.
Can burping be a sign of reflux?
Yes. Burping can occur alongside reflux or heartburn. If it happens frequently or causes discomfort, let us know so we can help.
Final Thoughts
Burping after sleeve gastrectomy is very common, especially during the early recovery phase. It is usually not a sign of a serious problem and tends to improve with time. You are not alone in experiencing this. If it continues or causes discomfort, please speak with us or our dietitian so we can help you manage it and feel more comfortable.
