Esophagitis: When Your Esophagus Becomes Inflamed

Quick Facts

  • Definition: Inflammation of the esophageal lining
  • Common Cause: Acid reflux (GERD) in most cases
  • Prevalence: Affects up to 20% of adults in Western countries
  • Treatment Success: 90% improve with proper treatment
  • Complications: Can lead to strictures or Barrett's esophagus if untreated

🚨 Seek Immediate Medical Care For:

  • Severe chest pain (rule out heart problems)
  • Complete inability to swallow (even saliva)
  • Food impaction (food stuck in esophagus)
  • Signs of bleeding (vomiting blood, black stools)
  • Severe dehydration from inability to drink
  • High fever with difficulty swallowing

What is Esophagitis?

Esophagitis is inflammation of the esophagus, the muscular tube that connects your throat to your stomach. This inflammation can damage the delicate tissues lining the esophagus, causing pain, difficulty swallowing, and other uncomfortable symptoms. The condition ranges from mild irritation to severe inflammation that can lead to complications such as scarring, narrowing of the esophagus, or precancerous changes.

The esophagus normally has protective mechanisms to prevent damage from stomach acid and other irritants. However, when these defenses are overwhelmed or compromised, the esophageal lining becomes inflamed. This inflammation can be acute, developing suddenly and lasting a short time, or chronic, persisting for weeks to months or recurring frequently.

Esophagitis affects people of all ages but is more common in adults. The condition can significantly impact quality of life, affecting eating habits, nutrition, sleep, and daily activities. Understanding the underlying cause is crucial for effective treatment, as different types of esophagitis require different therapeutic approaches.

Types of Esophagitis

Reflux Esophagitis (GERD-Related)

The most common type, reflux esophagitis results from stomach acid backing up into the esophagus. This occurs when the lower esophageal sphincter (LES), a ring of muscle at the junction of the esophagus and stomach, doesn't function properly. Chronic acid exposure irritates and inflames the esophageal lining, potentially causing erosions or ulcers.

Risk factors include obesity, pregnancy, hiatal hernia, smoking, and certain foods or medications. Without treatment, chronic reflux can lead to complications such as strictures (narrowing), Barrett's esophagus (precancerous changes), or rarely, esophageal cancer.

Eosinophilic Esophagitis (EoE)

This allergic condition involves accumulation of eosinophils (a type of white blood cell) in the esophageal lining. EoE is increasingly recognized, particularly in children and young adults. It's often associated with food allergies, environmental allergies, asthma, and eczema. Common trigger foods include milk, eggs, wheat, soy, peanuts, tree nuts, and seafood.

Unlike reflux esophagitis, EoE doesn't respond to acid-suppressing medications alone. Treatment typically involves dietary modifications, topical steroids, or both. Left untreated, EoE can cause fibrosis and strictures, leading to food impaction episodes.

Infectious Esophagitis

This type occurs when bacteria, viruses, fungi, or parasites infect the esophagus. It's most common in people with weakened immune systems, including those with HIV/AIDS, cancer patients receiving chemotherapy, organ transplant recipients, or those taking immunosuppressive medications.

Common pathogens include:

Drug-Induced (Pill) Esophagitis

Certain medications can cause esophageal injury if they remain in contact with the esophageal lining too long. This typically happens when pills are taken with insufficient water or while lying down. Common culprit medications include:

Radiation Esophagitis

This occurs as a side effect of radiation therapy to the chest or upper abdomen, commonly used for lung, breast, or esophageal cancers. Acute radiation esophagitis typically develops 2-3 weeks after starting treatment and may persist for several weeks after completion. Chronic changes can occur months to years later.

Lymphocytic Esophagitis

A recently recognized form characterized by increased lymphocytes in the esophageal lining. The cause is unclear, but it may be related to GERD or represent a distinct entity. Symptoms are similar to other forms of esophagitis.

Conclusion

Esophagitis encompasses a diverse group of inflammatory conditions affecting the esophagus, each with distinct causes, presentations, and treatments. While reflux-related esophagitis remains most common, recognition of other forms like eosinophilic esophagitis has improved diagnosis and treatment outcomes. Most patients respond well to appropriate therapy, though many require long-term management.

The key to successful management lies in accurate diagnosis, identifying underlying causes, and implementing comprehensive treatment strategies that address both symptoms and root causes. With proper medical care, lifestyle modifications, and adherence to treatment plans, most people with esophagitis can achieve excellent symptom control and prevent complications. Regular follow-up ensures optimal outcomes and early detection of any complications, allowing patients to maintain good quality of life despite this chronic condition.
