Barrett’s oesophagus is a condition where the lining of the esophagus is damaged and changes into tissue that is similar to the lining of the intestine. This intestinal cell type in the esophagus is a result of chronic reflux of stomach acid into the esophagus (acid reflux).
Risk Factors for Barrett’s oesophagus
There are certain risk factors that make a person more likely to develop Barrett’s oesophagus:
- Chronic acid reflux: Reflux of stomach acid that persists over many years is the main cause of Barrett’s oesophagus. Conditions that can contribute to chronic acid reflux include hiatal hernia, obesity, diet, and tobacco use.
- Age: Barrett’s oesophagus is more common in older adults, with incidence and prevalence increasing with age.
- Gender: Barrett’s oesophagus is more common in males than females.
- Race: Barrett’s oesophagus is seen more often in white populations as compared to other races.
- Family history: People with close relatives who have Barrett’s oesophagus may have a slightly increased risk themselves.
- Tobacco and alcohol use: Cigarette smoking and heavy alcohol use further increase the risk of developing Barrett’s oesophagus in people with chronic acid reflux.
Prevalence and Incidence of Barrett’s oesophagus Globally
It is estimated that over 8 million people worldwide have Barrett's Esophagus. The prevalence and incidence of the condition varies greatly based on geographical location:
- United States: Prevalence is estimated to be around 1-2% in the general population, and around 10% in patients with chronic reflux symptoms. Incidence is rising, with around 5-15 new cases per 100,000 people per year.
- Europe: Prevalence is lower than the U.S., around 0.5% in the general population. Incidence in European countries ranges from 1-5 new cases per 100,000 people per year.
- Asia: Most Asian countries have much lower rates than Western nations. Prevalence is estimated to be under 0.5% in China and India. Incidence is around 1 new case per 100,000 people per year in East Asian countries.
- Africa: Data is scarce, but available evidence suggests Barrett’s oesophagus is rare across most of the African continent. Incidence is estimated to be under 1 new case per 100,000 people per year.
These worldwide variations demonstrate strong environmental and lifestyle influences on the development of Barrett’s oesophagus. Areas with highest rates have traditionally Western diets and lifestyle patterns.
Monitoring and Managing Barrett's Esophagus Industry
Due to the risk of Barrett’s oesophagus progressing to esophageal cancer, it is important for patients diagnosed with this condition to undergo periodic surveillance endoscopy. During these exams:
- The esophagus is examined using an endoscope (a long, flexible tube inserted through the mouth).
- Biopsies (small tissue samples) are taken from different areas of the esophagus to check for dysplasia (precancerous changes) or malignancy under the microscope.
- Patients with no dysplasia typically repeat endoscopy every 3-5 years. Those with low-grade dysplasia are usually re-checked yearly.
Lifestyle changes can also help manage Barrett’s oesophagus. Maintaining a healthy weight, avoiding late meals, not smoking or drinking excessively, and elevating the head of the bed can reduce further esophageal acid exposure. Medications like PPIs provide additional protection by further reducing stomach acid. In some cases of high-grade dysplasia, radiofrequency ablation or endoscopic mucosal resection may be used to remove precancerous areas.
Barrett’s oesophagus is a serious complication of chronic acid reflux affecting over 8 million globally. Rates vary significantly worldwide based on environment and lifestyle factors. While mostly asymptomatic initially, ongoing surveillance is important due to the risk of progression to esophageal cancer over time. Adopting a healthy diet and lifestyle can help manage the condition and reduce future risk. Further research to better understand modifiable risk factors and improve monitoring techniques will help more effectively address this condition worldwide in the future.
