Understanding and Managing GERD

Gastroesophageal reflux disease (GERD) is a common chronic condition affecting an estimated 20% of people in the United States.¹ It occurs when stomach contents flow back up into the esophagus, causing irritation and a range of symptoms. While often manageable with lifestyle changes and medication, understanding the causes, symptoms, and potential complications of GERD is crucial for effective treatment and prevention.

What is GERD?

GERD develops when the lower esophageal sphincter (LES), a muscular ring that acts as a valve between the stomach and esophagus, relaxes inappropriately, allowing stomach acid to reflux into the esophagus.² This backflow can lead to troublesome symptoms like heartburn and regurgitation, or even more serious complications like erosive esophagitis.² GERD is sometimes referred to as acid indigestion, acid reflux, or heartburn.²

Symptoms of GERD

The most common symptom of GERD is frequent heartburn, a burning sensation in the middle of the chest.² Other symptoms can include:

• Regurgitation of stomach contents
• Chest pain
• Cough or hoarseness
• Subpar breath
• Nausea and vomiting
• Sore throat or an irritated feeling in the esophagus

The severity and frequency of symptoms can vary significantly from person to person.²

Diagnosing GERD

A doctor may suspect GERD based on a review of your medical history and a physical examination.¹ Diagnosis often begins with a trial of proton pump inhibitors (PPIs) to lower stomach acid production.¹ If symptoms improve with PPIs, it can confirm a diagnosis without further testing.¹ However, if symptoms persist or are atypical, further diagnostic tests may be recommended, including:

• Upper Endoscopy: A procedure using a thin, flexible tube with a camera to visualize the esophagus and stomach.^{1, 4}
• Ambulatory Acid (pH) Probe Test: Measures the amount of acid reflux in the esophagus over a 24-hour period.²
• Esophageal Manometry: Measures the muscle contractions in the esophagus during swallowing.²
• Upper Digestive System X-Ray: Can reveal narrowing of the esophagus or other abnormalities.²

Complications of GERD

While not usually life-threatening, untreated GERD can lead to several complications:

• Esophageal Stricture: Narrowing of the esophagus due to scar tissue buildup.²
• Esophageal Ulcer: An open sore in the esophagus caused by acid damage.²
• Barrett’s Esophagus: A precancerous condition where the esophageal lining changes.²
• Esophageal Cancer: A potential long-term risk associated with chronic, untreated GERD.²

Treatment and Management

Treatment for GERD typically involves a combination of lifestyle changes, medication, and, in some cases, surgery.

Lifestyle Modifications

• Avoid foods and beverages that trigger symptoms, such as alcohol, caffeine, fatty foods, spicy foods, peppermint, citrus fruits, tomatoes, and carbonated beverages.²
• Sit upright while eating.²
• Eat at least three hours before bedtime.²
• Maintain a healthy weight.²
• Eat slowly.²
• Quit smoking.²
• Avoid tight-fitting clothing.²
• Elevate the head of your bed.²

Medications

• Antacids: Neutralize stomach acid for quick, but mild, relief.²
• H-2-Receptor Blockers: Reduce acid production.²
• Proton Pump Inhibitors (PPIs): Suppress stomach acid and promote healing of esophageal inflammation.²

Surgical Options

If lifestyle changes and medications are insufficient, surgical options may be considered:

• Fundoplication: Strengthens the LES by wrapping the top of the stomach around the esophagus.²
• LINX Device: A ring of magnetic beads placed around the LES to prevent reflux.²
• Transoral Incisionless Fundoplication (TIF): A minimally invasive procedure to tighten the LES.⁴

Prognosis

The duration of GERD varies. Heartburn related to GERD can occur two or more times a week, or intermittently over several years.² Dietary adjustments and weight loss can sometimes reverse the condition, but others may require ongoing management with lifestyle changes and medication.²
