Acid reflux is a common condition where stomach acid flows backward into the esophagus, irritating its lining. The primary symptom is a burning chest pain known as heartburn. It is typically caused by a weakened or relaxed lower esophageal sphincter (LES). (Cleveland Clinic)

Key Symptoms

• Heartburn: A burning sensation in the chest that often rises toward the throat.
• Regurgitation: A sour or bitter-tasting acid backing up into your mouth or throat.
• Other signs: Chest pain, difficulty swallowing, chronic cough, or hoarseness. (Cleveland Clinic)

Common Causes & Triggers

• Lower Esophageal Sphincter (LES) Dysfunction: The muscle that acts as a valve between your esophagus and stomach relaxes at the wrong time.
• Hiatal Hernia: A condition where the upper part of the stomach pushes up through the diaphragm.
• Dietary Triggers: Fatty foods, citrus fruits, tomatoes, chocolate, caffeine, and alcohol can weaken the LES or increase acid.
• Lifestyle Factors: Eating large meals, lying down immediately after eating, obesity, and smoking. Hiatal Hernia: A condition where the upper part of the stomach pushes up through the diaphragm. (Mayo Clinic)

When It Becomes GERD

Occasional acid reflux is normal. However, if you experience acid reflux symptoms more than twice a week, it may be diagnosed as Gastroesophageal Reflux Disease (GERD). If left untreated, chronic GERD can lead to long-term complications such as esophagitis (inflammation) or Barrett's esophagus. (Mayo Clinic)

Management & Treatment

Mild or occasional reflux can often be managed with lifestyle changes:

• Avoid trigger foods and beverages.
• Eat smaller meals and avoid lying down for 2-3 hours after eating.
• Elevate the head of your bed. (John Hopkins)

For persistent symptoms, over-the-counter and prescription medications are available to neutralize or reduce stomach acid: 

• Antacids: Provide quick, temporary relief by neutralizing acid.
• H2 Blockers: Reduce acid production.
• Proton Pump Inhibitors (PPIs): Block acid production and allow the esophagus time to heal. (YouTube Medical Mutual)
