This article is educational and does not replace your doctor's advice. Seek urgent care for any red-flag symptoms.
What is it?
Rumination is the unconscious learned habit of contracting the abdominal wall during or right after eating, which pushes recently swallowed food back up. It is NOT vomiting (no nausea, no retching). The food is undigested, sweet/normal-tasting, and either re-swallowed or spit out.
How common is it?
Probably more common than recognized — affects 1-3% of adults. Often begins in childhood or after stressful events. Frequently missed for years.
Why does it happen?
Learned, often subconscious habit. Sometimes follows an episode of vomiting or stress. The brain "learns" to involuntarily contract the abdomen as a response to food.
Symptoms
- Effortless regurgitation of food within 10-15 minutes of eating
- Food tastes normal — not sour like reflux
- No retching, no nausea before regurgitation
- Often re-swallowed (rumination) or spit out
- Stops once food becomes acidic in the stomach
- Sometimes weight loss
Red flags — seek urgent medical care
Significant weight loss with regurgitation
Investigate for other diagnoses (gastroparesis, achalasia).
How is it diagnosed?
Diagnosis is clinical based on history. High-resolution esophageal manometry with impedance confirms the abdominal contractions during episodes. Endoscopy and gastric emptying study rule out other causes. Tests are NORMAL.
Outlook — what to expect
Excellent with diaphragmatic breathing therapy — most patients improve dramatically within weeks. Cognitive-behavioral techniques further help.
Treatment
Habits & Lifestyle
Diaphragmatic breathing is the cure.
- Diaphragmatic breathing during and after meals — consciously expand the belly while inhaling, contract during exhale.
- Practice with a pillow on the belly to feel it rise.
- Eat slowly, chew thoroughly.
- Sit upright for 30-60 minutes after eating.
Diet
No special diet — just eating habits.
- Smaller, more frequent meals may help.
Medications
Medications play a small role.
- Baclofen at low doses can reduce regurgitation in refractory cases.
- PPIs are NOT effective — this isn't reflux.
Procedures & Surgery
Procedures only for diagnosis.
- Esophageal manometry to confirm.
- Biofeedback or behavioral therapy — most effective treatment.
Questions to ask your doctor
Save this list or print it before your appointment — doctors appreciate prepared patients.
- Could my "reflux that doesn't respond to PPI" be rumination?
- Where can I learn diaphragmatic breathing for this?
