Ask Dr. K: Strategies to reduce constant belching

DEAR DOCTOR K: I burp constantly. What can I do to stop it?

DEAR READER: Occasional burping usually results when foods produce gas during the digestive process and that gas escapes through your mouth. But if you’re burping frequently, it is almost certainly the result of swallowing air. Many people swallow air when they breathe or speak without even realizing it.

You can probably reduce your belching by making lifestyle changes to decrease the amount of air you swallow. For example, don’t drink through a straw or chew gum. If you smoke, quit. Getting properly fitted dentures can help too, since loose dentures can also cause you to swallow air.

One relatively common cause of burping and belching is lactose intolerance. Lactose is a type of sugar found in dairy products. Many people have low levels of lactase, an enzyme that digests lactose. As a result, not all of the lactose can be digested.

If you don’t think you’ve got lactose intolerance, try making some other changes to your diet. For example, avoid carbonated drinks and whipped desserts, both of which trigger burping. Take a brisk stroll after eating. Physical activity encourages food to move through your digestive tract, and it helps relieve bloating and discomfort. Sleep on your stomach or right side. These positions aid in the escape of gas and ease the feeling of fullness.

Your doctor will also want to know about anxiety and psychological problems, since they can contribute to gastrointestinal symptoms. He or she will review your medications. Some drugs – especially those that contain the sugar alcohol sorbitol – can produce gas and bloating.

Your doctor may also refer you to a speech and swallow therapist. This professional can help you modify the way you swallow so that you take in less air. If lifestyle changes aren’t effective, a muscle-relaxant drug can help.
