Belching, gas and bloating can be embarrassing and uncomfortable. Here's what causes these signs and symptoms — and how you can minimize them.
Belching or passing gas (flatus) is natural and common. Excessive belching or flatus, accompanied by bloating, pain or swelling of the abdomen (distention), can occasionally interfere with daily activities or cause embarrassment. But these signs and symptoms usually don't point to a serious underlying condition and are often reduced with simple lifestyle changes.
When belching, gas or bloating interferes with your daily activities, there may be something wrong. Find out how to reduce or avoid gas and gas pains, and when you may need to see your health care provider.
Belching is commonly known as burping. It's your body's way of expelling excess air from your upper digestive tract. Most belching is caused by swallowing excess air. This air most often never even reaches the stomach but accumulates in the esophagus.
You may swallow excess air if you eat or drink too fast, talk while you eat, chew gum, suck on hard candies, drink carbonated beverages, or smoke. Some people swallow air as a nervous habit even when they're not eating or drinking.
Acid reflux or gastroesophageal reflux disease (GERD) can sometimes cause excessive belching by promoting increased swallowing.
Chronic belching may also be related to inflammation of the stomach lining or to an infection with Helicobacter pylori, the bacterium responsible for some stomach ulcers. In these cases, the belching is accompanied by other symptoms, such as heartburn or abdominal pain.
