Comparing biofeedback device vs diaphragmatic breathing for bloating relief: A randomized controlled trial.

Area of Science:

• Gastroenterology
• Respiratory Medicine
• Psychology

Background:

• Abdominal bloating affects approximately 18% of the global population.
• The efficacy of breathing exercises for alleviating bloating is not well-established.
• Functional abdominal bloating is a common and distressing condition.

Purpose of the Study:

• To investigate the impact of diaphragmatic breathing exercises on abdominal bloating.
• To compare the effectiveness of written instructions versus a biofeedback device (Calmigo®) for improving bloating.

Main Methods:

• A prospective study involving 85 participants randomized to two groups.
• Intervention groups practiced breathing exercises for 6 weeks (3 minutes, 3 times daily).
• Bloating severity was assessed weekly using online self-reported surveys.

Main Results:

• Both intervention groups showed improvement in bloating symptoms over time.
• Significant bloating reduction was observed by week 4 in the Calmigo® group and by weeks 3-5 in the written instructions group.
• Baseline anxiety and depression levels predicted bloating improvement.

Conclusions:

• Simple breathing exercises, whether guided by written instructions or a device like Calmigo®, can effectively reduce functional abdominal bloating.
• These breathing techniques represent a viable complementary approach for managing bloating symptoms.
• Further research may explore the psychological factors influencing treatment outcomes.
