Esophagitis Caused by GERD

Outline

GERD is the leading cause of esophagitis. Learn what causes esophageal inflammation, how it is graded, and how it is diagnosed and treated effectively.

Key Takeaways

  • GERD-related esophagitis affects approximately 30 to 40 percent of patients undergoing endoscopy for GERD, according to the ACG (2022). Esophagitis occurs when the protective mechanisms of the esophageal lining are overwhelmed by the effects of repeated exposure to acid.
  • The symptoms of esophagitis include heartburn, painful swallowing (odynophagia), difficulty swallowing (dysphagia), regurgitation, and in some cases, bleeding from ulceration. Symptom severity does not always reflect the degree of esophageal damage on endoscopy
  • Esophagitis severity is graded using the Los Angeles Classification from Grade A (mild erosions) to Grade D (circumferential ulceration). Grades C and D carry the highest risk of stricture, Barrett's esophagus, and bleeding
  • PPIs heal erosive esophagitis in 78 to 95 percent of patients according to the AGA (2022) when taken correctly for 8 weeks. Taking 30 to 60 minutes before the first meal maximizes PPI effectiveness
  • Esophagitis recurs in the majority of patients after stopping PPIs without addressing underlying GERD. Long-term maintenance therapy, lifestyle modifications, and consideration of anti-reflux surgery prevent recurrence

What Causes Esophagitis in GERD?

The reason behind the occurrence of esophagitis in the case of GERD is the repeated failure of the lower esophageal sphincter to keep the stomach acid out of the esophagus. This is because the esophagus is not lined with the mucus layer that protects the stomach from its own acid. As the acid comes into repeated contact with the esophagus, the process of inflammation is initiated.

Several factors determine the severity of esophagitis:

  • Frequency and duration of acid exposure episodes
  • Acidity of the refluxed material
  • Presence of bile in the refluxate, which compounds acid-induced damage
  • Individual susceptibility, including esophageal motility and mucosal defense mechanisms
  • Obesity, smoking, and hiatus hernia all increase esophagitis severity

What Are the Symptoms of Esophagitis From GERD?

Esophagitis symptoms reflect the degree of esophageal inflammation and tissue damage:

  • Heartburn: A burning sensation in the chest or throat, typically worse after meals and when lying down
  • Odynophagia: Pain during swallowing, particularly with solid foods
  • Dysphagia: Difficulty in swallowing caused by the inflammation and swelling of the esophagus, which leads to the narrowing of the esophagus.
  • Regurgitation of acid or food into the throat or mouth.
  • Chest pain, which is cardiac in origin but related to food intake and posture.
  • Nausea and discomfort in the upper abdomen.
  • Bleeding: Ulceration caused by esophagitis leads to bleeding, which is manifested by blood in vomit or black tarry stools.

Some patients with severe esophagitis report paradoxically mild symptoms due to reduced pain sensitivity from chronic esophageal inflammation. This makes endoscopic evaluation important for assessing actual esophageal damage severity independent of symptom severity.

How Is Esophagitis Graded?

Esophagitis severity is graded using the Los Angeles (LA) Classification system, the internationally accepted endoscopic grading system for reflux esophagitis:

  • Grade A: One or more mucosal breaks (erosions) less than 5 mm in length, not extending between the tops of two mucosal folds
  • Grade B: One or more mucosal breaks more than 5 mm in length, not extending between the tops of two mucosal folds
  • Grade C: Mucosal breaks extending between the tops of two or more mucosal folds but involving less than 75 percent of the esophageal circumference
  • Grade D: Mucosal breaks involving 75 percent or more of the esophageal circumference

Grade A and B represent mild to moderate esophagitis. Grade C and D represent severe esophagitis with significantly higher risk of complications, including stricture formation, Barrett's esophagus, and esophageal bleeding.

How Is Esophagitis From GERD Diagnosed?

Upper Endoscopy

Upper endoscopy (gastroscopy) is the gold standard for diagnosing and grading esophagitis. During endoscopy, the gastroenterologist directly visualizes the esophageal lining, identifies erosions, ulcers, and the extent of mucosal damage, and assigns an LA Classification grade. Biopsies may be taken to exclude other causes of esophagitis, including eosinophilic esophagitis, and to assess for Barrett's esophagus.

Esophageal pH Monitoring

Esophageal pH monitoring objectively measures the frequency and duration of acid exposure in the esophagus. pH monitoring is useful when endoscopy shows normal esophageal mucosa in a patient with significant symptoms, when the diagnosis of GERD-related esophagitis is uncertain, or before anti-reflux surgery to confirm pathological acid exposure.

Upper endoscopy is recommended in GERD patients who have:

  • Alarm symptoms include dysphagia, odynophagia, bleeding, or unintentional weight loss
  • GERD symptoms persisting or worsening despite adequate PPI therapy
  • Long-standing GERD symptoms (more than 5 years) to screen for Barrett's esophagus
  • New onset of GERD symptoms after age 60

Proton Pump Inhibitors (PPIs)

PPIs are the most effective treatment for esophagitis associated with GERD. PPIs work by reducing the production of acid in the stomach through the suppression of the proton pump enzyme in the parietal cells of the stomach lining, thus significantly reducing the amount of acid in the esophagus, which enables the esophageal lining to heal.

PPIs, as recommended by the AGA (2022), can heal erosive esophagitis in 78-95% of patients who use them for 8 weeks. Some of the key principles of PPI use in the treatment of esophagitis include:

  • Take PPIs 30 to 60 minutes before the first meal of the day for maximum effectiveness
  • The standard treatment course for erosive esophagitis is 8 weeks
  • Grade C and D esophagitis may require extended PPI therapy beyond 8 weeks
  • Repeat endoscopy after PPI therapy confirms healing, particularly for high-grade esophagitis

Commonly prescribed PPIs include omeprazole, esomeprazole, lansoprazole, and pantoprazole.

Maintenance PPI Therapy

Esophagitis recurs in the majority of patients after stopping PPI therapy if the underlying GERD is not addressed through lifestyle changes or surgery. Long-term maintenance PPI therapy is recommended for patients with:

  • Grade C or D erosive esophagitis
  • Barrett's esophagus
  • Frequent relapsing esophagitis despite lifestyle modifications
  • Inability to control GERD through lifestyle changes alone

Lifestyle Modifications

Lifestyle modifications reduce acid exposure and aid healing along with PPI therapy:

  • Weight loss in overweight and obese patients relieves increased intra-abdominal pressure
  • Not eating 2 to 3 hours before bedtime relieves nocturnal acid exposure
  • Raising the head of the bed by 6 to 8 inches relieves nighttime reflux
  • Avoiding trigger foods, alcohol, and tobacco relieves the direct cause of LES dysfunction and mucosal damage

Anti-Reflux Surgery

For patients with confirmed severe or recurrent esophagitis not adequately controlled by PPI therapy, anti-reflux surgery, including laparoscopic Nissen fundoplication or LINX device placement, restores LES competence and eliminates acid reflux. Surgery is considered after thorough pre-surgical evaluation confirming GERD as the cause of esophagitis and adequate esophageal motility on manometry.

Conclusion

As a result of GERD, esophagitis is a common condition that is of significant importance. If esophagitis is diagnosed early enough and managed adequately, it can heal well in most cases. However, esophagitis can cause stricture, Barrett's, and cancer if not managed adequately. Thus, in case you are experiencing heartburn, difficulty in swallowing, or any alarm symptom, it is essential to seek medical evaluation and endoscopy as soon as possible.

Frequently Asked Questions

How long does esophagitis from GERD take to heal?

Mild to moderate esophagitis, or esophagitis of LA grade A and grade B, heals within 4 to 8 weeks with appropriate PPI therapy. Severe esophagitis, or esophagitis of grade C and grade D, may require longer PPI therapy, 12 weeks or more. Repeat endoscopy confirms healing and determines the length of time for maintenance therapy.

Can esophagitis from GERD heal on its own without medication?

Mild esophagitis may show some signs of improvement with strict lifestyle modifications alone, such as weight loss, dietary changes, and avoiding late meals. However, for severe erosive esophagitis, PPI therapy is needed to provide adequate acid suppression for healing. If left untreated, esophagitis will progress to stricture, Barrett's, and bleeding.

Is esophagitis from GERD dangerous?

If left untreated, the esophagitis will only continue to deteriorate and cause serious problems, such as difficulty in swallowing due to esophageal stricture, Barrett’s esophagus with cancer potential, and esophageal bleeding. The highest complication risk is associated with grade C and D esophagitis. The use of PPIs and lifestyle changes will prevent serious consequences in the majority of patients.

Can esophagitis from GERD cause chest pain?

Yes. Esophagitis is one of the common causes of chest pain due to esophagitis. GERD-related chest pain is usually associated with meals, changes in posture, and lying down. The cardiac causes of chest pain must be ruled out before attributing the cause of the pain to esophagitis in patients over the age of 40 with cardiac risk factors.

Does esophagitis increase the risk of Barrett's esophagus?

Yes. Severe or recurrent esophagitis significantly increases the risk of Barrett's esophagus development through repeated cycles of acid-induced injury and abnormal healing. Effective and sustained PPI therapy reducing esophageal acid exposure is associated with lower rates of Barrett's esophagus progression, according to Gut (2014). Endoscopic surveillance after healing of severe esophagitis is recommended.
