GERD (Gastroesophageal Reflux Disease)
Gastroesophageal reflux disease (GERD) is a digestive disorder that occurs when stomach acid frequently flows back into the esophagus. This backwash of acid, often called acid reflux, can irritate the lining of the esophagus and cause uncomfortable symptoms.
Key Takeaways
- GERD is a chronic form of acid reflux.
- The most common symptoms include heartburn and regurgitation.
- Lifestyle changes and medications can often help control symptoms.
- Untreated GERD may lead to complications affecting the esophagus.
Common Symptoms of GERD
Symptoms of GERD can vary from mild to severe. Many people experience symptoms after eating or when lying down.
- Heartburn (burning sensation in the chest)
- Regurgitation of stomach acid
- Chest discomfort
- Difficulty swallowing
- Chronic cough or throat irritation
- Hoarseness or sore throat
- Sensation of a lump in the throat
What Causes GERD?
GERD develops when the lower esophageal sphincter (LES), a muscle that normally prevents stomach contents from moving upward, becomes weakened or relaxes inappropriately.
Several factors can contribute to GERD, including:
- Obesity or excess abdominal weight
- Hiatal hernia
- Smoking
- Certain medications
- Pregnancy
- Large meals or lying down soon after eating
How GERD Is Diagnosed
Diagnosis typically begins with a review of symptoms and medical history. If symptoms persist or complications are suspected, additional tests may be recommended.
- Upper endoscopy to examine the esophagus
- pH monitoring to measure acid exposure
- Imaging studies when needed
An upper endoscopy allows your gastroenterologist to evaluate inflammation and other changes in the esophagus.
Treatment Options
Treatment for GERD focuses on reducing acid reflux and preventing damage to the esophagus.
- Lifestyle changes such as dietary modification and weight management
- Medications that reduce stomach acid
- Avoiding trigger foods
- Elevating the head of the bed during sleep
- Surgical or procedural treatments in select cases
Possible Complications
If GERD is not treated, chronic acid exposure can lead to complications including:
- Esophagitis (inflammation of the esophagus)
- Narrowing of the esophagus
- Barrett’s esophagus
- Increased risk of esophageal cancer in rare cases
When to Seek Medical Care
You should seek evaluation if heartburn or reflux occurs frequently, interferes with daily life, or is accompanied by symptoms such as difficulty swallowing, unexplained weight loss, persistent vomiting, or chest pain.
Frequently Asked Questions
What is GERD?
GERD is a chronic digestive condition in which stomach acid repeatedly flows back into the esophagus, causing irritation and symptoms such as heartburn.
What is the difference between GERD and occasional acid reflux?
Occasional acid reflux can happen after certain meals, but GERD involves frequent or persistent reflux that may require medical evaluation and treatment.
What foods can trigger GERD?
Common triggers include spicy foods, fatty meals, caffeine, chocolate, alcohol, and acidic foods.
How is GERD treated?
Treatment may include lifestyle changes, medications that reduce stomach acid, and in some cases procedural or surgical treatments.
Can GERD cause complications?
Yes. Chronic acid reflux can lead to inflammation of the esophagus, narrowing of the esophagus, or Barrett’s esophagus if untreated.
