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.
