Acid Reflux (GERD)

Gastroesophageal Reflux Disease (GERD): Understanding, Symptoms, and Management

Gastroesophageal reflux disease (GERD) is a chronic condition where stomach acid or bile irritates the food pipe (esophagus). It occurs when the lower esophageal sphincter (LES), which usually keeps stomach acid from entering the esophagus, becomes weakened or relaxes inappropriately. This leads to the reflux of stomach contents into the esophagus, causing discomfort and potential damage to the esophageal lining.

Symptoms of GERD

The symptoms of GERD can vary in severity, and they may worsen after meals or when lying down. Common symptoms include:

  • Heartburn: A burning sensation in the chest, often after eating, which may be worse at night.
  • Regurgitation: A sour or bitter-tasting acid coming back up into the throat or mouth.
  • Difficulty swallowing: A sensation of food being stuck in the throat or chest.
  • Chronic cough: A persistent cough, often occurring at night or after meals.

Symptoms can be aggravated by eating large meals, certain foods, or lying flat (American College of Gastroenterology [ACG], 2025).

Complications of GERD

If GERD is left untreated, it can lead to serious complications:

  • Esophagitis: Inflammation of the esophagus that can lead to sores, ulcers, and bleeding.
  • Barrett’s esophagus: A condition where the lining of the esophagus changes, increasing the risk of esophageal cancer.
  • Increased risk of esophageal cancer: Long-term GERD can damage the esophagus and lead to cellular changes that may increase the risk of cancer (Mayo Clinic, 2025).

Medications for GERD

The treatment of GERD typically involves medications to reduce stomach acid and manage symptoms. Common medications include:

  • Proton Pump Inhibitors (PPIs): These medications, such as omeprazole and esomeprazole, reduce stomach acid production and allow the esophagus to heal.
  • H2 Blockers: These medications, like ranitidine and famotidine, also decrease acid production but are typically less potent than PPIs.
  • Antacids: Over-the-counter medications like Tums or Maalox provide immediate relief from heartburn by neutralizing stomach acid (National Institute of Diabetes and Digestive and Kidney Diseases [NIDDK], 2025).

Lifestyle Considerations for Managing GERD

In addition to medications, several lifestyle changes can help alleviate GERD symptoms:

  • Avoid trigger foods: Foods like spicy, fatty, or acidic foods, chocolate, caffeine, and alcohol can exacerbate GERD.
  • Eat smaller, more frequent meals: Large meals can increase the likelihood of acid reflux. Eating smaller meals helps reduce this risk.
  • Elevate the head during sleep: Raising the head of the bed by 6-8 inches can help prevent acid from flowing back into the esophagus during sleep (American Gastroenterological Association [AGA], 2025).

Conclusion

Effective management of GERD often involves a combination of medication and lifestyle modifications. While medications can help control symptoms and promote healing, lifestyle adjustments—such as dietary changes and proper sleeping habits—are crucial for preventing flare-ups and long-term complications. If left untreated, GERD can lead to serious health issues, making it essential to manage the condition appropriately.
