Regurgitation
Regurgitation is the effortless return of stomach contents into the mouth or throat without the forceful muscle contractions associated with vomiting. Unlike vomiting, regurgitation typically occurs without warning, nausea, or retching. Understanding the difference between normal reflux and concerning regurgitation is essential for proper management.
⚠️ Seek Emergency Care For:
- Regurgitation with chest pain or pressure
- Difficulty breathing or choking on regurgitated material
- Signs of aspiration (coughing, wheezing after regurgitation)
- Blood in regurgitated material
- Sudden onset with severe symptoms
- Regurgitation with high fever
- Signs of dehydration from frequent regurgitation
- Inability to keep any food or liquids down
Definition and Overview
Regurgitation involves the passive movement of stomach contents back up through the esophagus and into the throat or mouth. This differs from vomiting, which involves active muscle contractions and is often preceded by nausea. The regurgitated material may taste sour or bitter due to stomach acid, or it may taste like recently consumed food if it hasn't been fully digested.
The symptom can range from occasional minor episodes to frequent, troublesome occurrences that significantly impact quality of life. In infants, some degree of regurgitation (spitting up) is normal and typically resolves as they mature. In adults, persistent regurgitation often indicates an underlying digestive disorder requiring evaluation.
Common Causes
Gastroesophageal Conditions
- GERD: Most common cause in adults
- Hiatal hernia: Stomach pushes through diaphragm
- Esophageal motility disorders: Abnormal muscle function
- Achalasia: Lower esophageal sphincter fails to relax
- Esophageal stricture: Narrowing of esophagus
- Zenker's diverticulum: Pouch in throat wall
Structural Abnormalities
- Esophageal rings or webs: Tissue formations
- Tumors: Benign or malignant growths
- Previous surgery: Especially gastric procedures
- Congenital abnormalities: Present from birth
- Scleroderma: Connective tissue disease
Functional Causes
- Rumination syndrome: Behavioral condition
- Eating disorders: Bulimia nervosa
- Gastroparesis: Delayed stomach emptying
- Functional dyspepsia: Non-ulcer stomach pain
- Pregnancy: Hormonal and physical changes
Lifestyle Factors
- Overeating: Stomach overfilling
- Lying down after meals: Gravity effects
- Tight clothing: Abdominal pressure
- Certain foods: Fatty, spicy, acidic
- Alcohol and smoking: Sphincter relaxation
- Obesity: Increased abdominal pressure
Associated Symptoms
Regurgitation often occurs alongside other digestive symptoms:
- Heartburn: Burning sensation in chest
- Difficulty swallowing: Food sticking sensation
- Chest pain: Non-cardiac chest discomfort
- Chronic cough: Especially at night
- Hoarseness: Voice changes from acid exposure
- Bad breath: From regurgitated material
- Sore throat: Acid irritation
- Dental erosion: From repeated acid exposure
- Nausea: Though less common than with vomiting
- Weight loss: If eating becomes difficult
When It's Serious
Red Flag Symptoms
- Progressive difficulty swallowing
- Unintentional weight loss
- Persistent vomiting with regurgitation
- Blood or coffee-ground material
- Severe chest pain
- Signs of aspiration pneumonia
- Dehydration or malnutrition
- New onset after age 50
Complications to Watch For
- Aspiration: Breathing in regurgitated material
- Esophagitis: Inflammation from acid exposure
- Barrett's esophagus: Precancerous changes
- Strictures: Scarring and narrowing
- Dental problems: Enamel erosion
- Respiratory issues: Asthma, pneumonia
Diagnostic Approach
Medical Evaluation
- Detailed symptom history and timing
- Differentiation from vomiting
- Diet and lifestyle assessment
- Medication review
- Physical examination
Common Tests
- Upper endoscopy: Direct visualization of esophagus
- Barium swallow: X-ray with contrast
- Esophageal manometry: Muscle function testing
- 24-hour pH monitoring: Acid measurement
- Gastric emptying study: For gastroparesis
- CT or MRI: For structural abnormalities
Home Care Tips
Dietary Modifications
- Eat smaller, more frequent meals
- Avoid eating 3 hours before bed
