Aerophagia is the medical term for involuntarily swallowing air, which can lead to excessive belching, explains Healthline. Causes of aerophagia include eating and talking at the same time, smoking, chewing gum, and drinking through a straw.

Gastrointestinal reflux disease, also known as GERD, is a condition in which the muscle at the end of the esophagus, known as the lower esophageal sphincter, does not fully close, reports WebMD. This causes stomach acid to leak into the esophagus, which results in inflammation and irritation. Belching, heartburn, sore throat and difficulty swallowing are common symptoms of GERD.

Gastroparesis is a condition where the muscles in the stomach wall are weakened, which leads to a delay in the emptying of the contents of the stomach into the colon and causes belching, according to Healthline. Lactose intolerance is another possible cause of excessive belching, and it occurs in people whose digestive system are unable to process dairy products, which leads to symptoms of abdominal distress.
