What Causes Acid Reflux and GERD?

At Premier Gastroenterology in Katy, TX, serving Richmond, Fulshear, Houston, and Cypress, we diagnose and treat patients who struggle with persistent heartburn and digestive discomfort. Although many people use the terms interchangeably, acid reflux and GERD represent different stages of the same underlying problem. Understanding the causes of each allows us to recommend targeted and effective treatment.

The Root Cause: Lower Esophageal Sphincter Dysfunction

Both acid reflux and GERD occur when the lower esophageal sphincter fails to close properly. This muscle normally acts as a valve between the stomach and the esophagus. When it weakens or relaxes inappropriately, stomach acid flows backward into the esophagus, causing irritation.

Acid reflux describes occasional episodes of this backflow. GERD develops when reflux becomes frequent, typically occurring two or more times per week, and leads to inflammation or tissue damage. Persistent acid exposure distinguishes GERD from occasional reflux.

Common Triggers and Risk Factors

Several lifestyle and medical factors increase the likelihood of reflux. These include:

• Large or late-night meals
• Fatty, spicy, or acidic foods
• Caffeine and alcohol
• Smoking
• Obesity
• Pregnancy
• Hiatal hernia

While these triggers may cause isolated acid reflux in many individuals, they can contribute to chronic symptoms in patients with GERD.

Symptoms: Occasional vs. Chronic

Acid reflux may cause temporary heartburn, regurgitation, or a sour taste in the mouth. GERD produces more persistent symptoms and may also lead to chronic cough, hoarseness, difficulty swallowing, chest discomfort, or throat irritation. Without treatment, GERD can result in complications such as esophagitis or Barrett’s esophagus.

How We Diagnose and Treat Both Conditions

We begin with a detailed symptom history and physical evaluation. When symptoms suggest chronic GERD or complications, we may recommend upper endoscopy to examine the esophageal lining directly. We individualize care based on symptom frequency, severity, and risk factors.

Treatment often includes dietary adjustments, weight management, avoiding meals close to bedtime, and elevating the head during sleep. We may prescribe medications such as proton pump inhibitors to reduce acid production and allow healing. If alarm symptoms appear, further testing ensures we address any underlying issues promptly.
