Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Dysphagia
Difficulty or discomfort when swallowing food or liquids, often described as food getting stuck in the throat or chest.
Seek immediate medical attention if dysphagia causes weight loss, vomiting, or if food frequently gets stuck.
Chest Pain
Pressure, squeezing, or burning pain in the chest that may be difficult to distinguish from heart-related pain.
Seek emergency care if chest pain is severe, radiates to arm/jaw, or is accompanied by shortness of breath.
Heartburn
(gastrointestinal)Burning sensation in the chest that may spread toward the throat, often worse after eating or when lying down.
Frequency: 75-90% of patients
Regurgitation
(gastrointestinal)Backflow of undigested food or stomach acid into the mouth, often accompanied by a sour or bitter taste.
Frequency: 45-65% of patients
Unintended Weight Loss
(constitutional)Gradual loss of body weight without intentional dietary changes, often due to reduced food intake from swallowing difficulties.
Frequency: 30-50% of patients
Chronic Cough
(respiratory)Persistent cough lasting more than 8 weeks, often caused by acid irritation or aspiration of stomach contents into the airways.
Frequency: 35-55% of patients
Odynophagia
(gastrointestinal)Painful swallowing that may feel like a sharp or burning sensation in the chest or throat when eating or drinking.
Frequency: 15-25% of patients
Hoarseness
(respiratory)Changes in voice quality making it sound raspy, breathy, or strained, often due to irritation of the vocal cords from acid reflux.
Frequency: 10-20% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Acid-suppressing medications
Proton pump inhibitors or H2 blockers reduce gastric acid production, allowing esophageal tissue to heal and reducing symptoms of reflux or irritation. These are typically prescribed for short to medium-term use with gradual tapering when appropriate.
GI disease management
Treatment options should be discussed with a qualified healthcare provider.
Esophageal-friendly diet
Avoiding trigger foods such as caffeine, chocolate, spicy foods, citrus, and fatty meals can reduce esophageal irritation and reflux symptoms. Eating smaller, more frequent meals and avoiding late-night eating helps maintain proper digestive function.
Additional treatment options
Sleep positioning and meal timing
Elevating the head of the bed and waiting at least 2-3 hours after eating before lying down reduces reflux episodes. Weight management and avoiding tight clothing also decrease intra-abdominal pressure on the esophagus.
lifestyleDiagnostic endoscopy
Upper endoscopy allows direct visualization of esophageal tissue to assess damage, obtain biopsies, and rule out serious conditions. The procedure can also be used for therapeutic interventions if needed.
procedureEsophageal function monitoring
Esophageal pH monitoring or manometry tests assess the frequency and severity of acid reflux or motility disorders. Regular follow-up helps track disease progression and treatment effectiveness.
