What it means:
You’ve swallowed excess air, either while eating or conversing or both. But burps and gurgles can also point to gastroesophageal reflux disease (GERD), a common condition that often develops from overeating or pressure on the stomach (up to 50 percent of pregnant women suffer from it). Stomach acid seeps up into your esophagus, where it can cause heartburn, burping, chest pain, sore throat, hoarseness, bad breath―and, in serious cases, gurgling noises caused by regurgitation of food or acid.
What to do: Well, like your mom said, don’t talk with your mouth full. That can cut back on burping, as can limiting gum-chewing and fizzy beverages. To avoid GERD, eat small, frequent meals, skip foods that worsen the symptoms (like caffeinated drinks, onions, chocolate and garlic) and nix postmeal naps. You may also get relief from a nonprescription antacid.
