Constant burping can be a sign of various conditions, including:

• Swallowing air: Aerophagia, or swallowing air, is the most common cause of excessive burping. It can happen while drinking soda or chewing gum, and the swallowed air gets trapped in the esophagus and stomach, leading to burping.

• Gastrointestinal conditions: Excessive burping may be due to gastrointestinal conditions such as irritable bowel syndrome (IBS), lactose intolerance, or food sensitivities.

• Stomach ulcers: Sometimes, burping can be a sign of stomach ulcers. An infection or taking too many NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen can cause them. If you have an ulcer, you may burp more and feel full or bloated after eating fatty foods. Your stomach may also hurt after you eat.

• Constipation: Constipation could cause another digestive symptom: excessive burping. Some causes of constipation include changes in diet.

• Hiatal hernia: If the upper part of your stomach pushes through your diaphragm and up into your chest, you have what’s called a “hiatal hernia.” This can cause stomach acid to back up into your throat, which can give you sour-tasting burps. Some people also find it harder to swallow.

If you are concerned about how much you burp, it is best to talk with your doctor. They might have some suggestions to help keep it from happening and may run tests to look for signs of a health problem.
