Rumination syndrome (RS) is more common than previously thought, affecting 3.1% globally. High-resolution manometry with impedance (HRM/Z) aids diagnosis, and cognitive behavioral therapy (CBT) effectively treats regurgitation.
Area of Science:
- Gastroenterology
- Functional Gastrointestinal Disorders
Background:
- Rumination syndrome (RS) is a functional gastroduodenal disorder often underdiagnosed.
- Characterized by effortless regurgitation of food without retching.
Approach:
- Review of epidemiological data and diagnostic techniques for RS.
- Discussion of management strategies including pharmacological and behavioral therapies.
Key Points:
- Global prevalence of RS is 3.1%, higher than previously assumed.
- High-resolution manometry with impedance (HRM/Z) is a gold standard for diagnosing RS.
- Cognitive behavioral therapy (CBT) is highly effective in eliminating regurgitation.
Conclusions:
- RS is a prevalent condition requiring increased clinical recognition.
- HRM/Z differentiates RS from gastroesophageal reflux disease.
- CBT offers a highly effective therapeutic option for managing RS.
