Study: Singing Therapy May Be More Effective Than Breathing Exercises for Chronic Belching

Singing therapy may offer a more effective and enjoyable treatment for people with supragastric belching, a chronic gastrointestinal disorder that can severely affect quality of life, according to a randomized clinical trial published in Clinical Gastroenterology and Hepatology.

The study is the first randomized controlled trial to evaluate singing as a behavioral therapy for supragastric belching—a condition in which air repeatedly enters and exits the esophagus instead of the stomach, causing excessive belching that can occur hundreds or even thousands of times a day.

The trial enrolled 72 adults diagnosed with the condition, who were randomly assigned to either structured singing therapy or diaphragmatic breathing therapy, the current standard behavioral treatment. Researchers assessed symptom severity, quality of life, and treatment satisfaction over a one-month follow-up period.

After just one week, 72.2% of participants in the singing therapy group experienced at least a 50% reduction in symptom severity, compared with 38.9% of those practicing diaphragmatic breathing. One month later, the benefits remained greater in the singing group, with response rates of 50% versus 30.6%.

Participants receiving singing therapy also reported greater improvements in quality of life and were more likely to describe the treatment as enjoyable.

Researchers believe singing may be easier for patients to maintain because it combines breathing control with an engaging activity. Although both treatment approaches reduced symptoms, singing therapy produced stronger and more sustained improvements.

The study also identified three factors associated with better treatment outcomes: participation in singing therapy, older age, and greater symptom severity at the start of treatment. According to the researchers, older patients and those with more severe symptoms may benefit the most from this approach.

The authors caution that the findings should be interpreted in light of several limitations, including the relatively short one-month follow-up period, the enrollment of participants from a single cultural population, and the inability to blind patients to the type of behavioral therapy they received. Further research is needed to evaluate the long-term effectiveness of singing therapy and its applicability to more diverse populations.
