Abstract：
A 52-year-old woman had a 6-month history of frequent belching;however, esophagogastroduodenoscopy revealed no abnormal findings. She presented to our department with belching refractory to several medications. Abdominal radiography revealed no massive gas in the stomach and intestine. She had frequent belching during the medical interview but no belching during speaking. Findings from high-resolution esophageal manometry and esophageal impedance pH monitoring confirmed supragastric belching. Thus, she was diagnosed as having excessive supragastric belching, which improved with cognitive behavioral therapy.
