Food regurgitation is the involuntary return of undigested or partially digested food from the stomach to the mouth. This symptom is often associated with various gastrointestinal conditions and can significantly impact a person’s quality of life.

Causes

The main causes of food regurgitation include:

• Gastroesophageal reflux disease (GERD): The most common cause, occurring when stomach acid frequently flows back into the esophagus.
• Weak lower esophageal sphincter (LES): When the LES doesn’t close properly, it allows stomach contents to flow back up.
• Hiatal hernia: This condition can compromise the LES’s ability to prevent reflux.
• Rumination syndrome: A rare condition causing frequent regurgitation of undigested food shortly after eating.
• Pregnancy: Hormonal changes and increased abdominal pressure can lead to regurgitation.

Symptoms

Food regurgitation is often accompanied by:

• A sour or bitter taste in the mouth
• Chest discomfort or burning sensation (heartburn)
• Difficulty swallowing
• Feeling of food stuck in the throat
• Nausea

In cases of rumination syndrome, regurgitation typically occurs within minutes of eating and doesn’t involve retching.

Diagnosis

Diagnosis of the underlying cause of regurgitation may involve:

• Medical history review
• Physical examination
• Endoscopy
• pH monitoring
• Gastric emptying studies

Management

Treatment depends on the underlying cause but may include:

• Lifestyle modifications:
  • Eating smaller, more frequent meals
  • Avoiding trigger foods and beverages
  • Not lying down immediately after eating
  • Losing weight if overweight
• Medications:
  • Antacids for quick relief
  • H2 blockers
  • Proton pump inhibitors (PPIs)
• Behavioral therapy: Particularly effective for rumination syndrome.
• Surgical interventions: In severe cases of GERD, procedures like fundoplication may be considered.

While medications like PPIs are effective for treating heartburn, they may be less effective for regurgitation symptoms.
