What is Barrett’s Esophagus?

Barrett’s esophagus is a condition in which the normal lining of the esophagus, the tube that connects the throat to the stomach, is replaced by a different type of lining. This new lining is more similar to the lining of the intestine and is a result of chronic acid reflux or gastroesophageal reflux disease (GERD).

Symptoms of Barrett’s Esophagus

Barrett’s esophagus alone does not cause any specific symptoms. However, because it is closely linked to GERD, the symptoms of GERD are often present in individuals with Barrett’s esophagus. These symptoms can include:

• Heartburn: A burning sensation that can run from the throat to the center of the chest
• Regurgitation of sour liquid or food
• Difficulty swallowing (if this occurs, seek medical attention immediately)

Risk Factors for Barrett’s Esophagus

Several factors can increase the risk of developing Barrett’s esophagus, including:

1. Chronic heartburn, acid reflux, or GERD: Those with long-term (more than five years) symptoms are more likely to develop Barrett’s esophagus.
2. Age: Barrett’s esophagus is more common in middle-aged and older adults, with the average age of diagnosis being 55.
3. Gender: Men are more likely to develop Barrett’s esophagus than women.
4. Ethnic background: White and Hispanic populations are at higher risk than other populations, while Black and Asian populations have a lower risk.
5. Smoking: Current and past smokers are more likely to develop Barrett’s esophagus.

Diagnosing Barrett’s Esophagus

To diagnose Barrett’s esophagus, a doctor will typically perform an upper endoscopy, a procedure that allows them to examine the esophagus and stomach using a small, lighted tube. During the endoscopy, the doctor may take small tissue samples (biopsies) to confirm the diagnosis and look for any precancerous changes (dysplasia).

The diagnosis can be challenging due to anatomical differences between patients, and because Barrett’s esophagus may not affect all the tissue in the esophagus, making it difficult to detect in some cases. Pathologists, who are experts in examining tissue samples, will help confirm the presence and degree of any precancerous changes.

Treating Barrett’s Esophagus

The primary goal of treating Barrett’s esophagus is to stop the damage to the esophagus, which is typically achieved by eliminating acid reflux. This can be done through a combination of lifestyle changes and medications:

• Lifestyle changes to reduce acid reflux:
  • Maintaining a healthy weight
  • Quitting smoking
  • Raising the head of the bed to keep acid in the stomach while sleeping
• Medications to reduce stomach acid:
  • Proton pump inhibitors (PPIs) such as omeprazole (Prilosec), lansoprazole (Prevacid), and esomeprazole (Nexium)

Monitoring and Complications

For most people with Barrett’s esophagus, doctors recommend periodic screening endoscopies to look for signs of cancer. This approach is called surveillance. The frequency of these endoscopies will depend on the extent of the precancerous changes (dysplasia) in the esophagus.

One potential complication of Barrett’s esophagus is the development of esophageal cancer, but this is uncommon. Studies show that only about 0.5% of patients with Barrett’s esophagus develop esophageal cancer each year. Furthermore, patients with Barrett’s esophagus appear to live just as long as those without the condition, as they often die from other causes before the Barrett’s esophagus progresses to cancer.

Key Takeaways

Barrett’s esophagus is a condition in which the normal lining of the esophagus is replaced by a different type of lining, often due to chronic acid reflux or GERD. While Barrett’s esophagus itself does not cause any specific symptoms, the symptoms of GERD, such as heartburn and regurgitation, are often present. Risk factors include chronic GERD, age, gender, ethnicity, and smoking. Diagnosis is made through an endoscopy and biopsy, and treatment focuses on eliminating acid reflux through lifestyle changes and medications. Regular monitoring is important, as Barrett’s esophagus can potentially lead to esophageal cancer, although this progression is uncommon.
