Barrett's esophagus is a condition in which the normal lining of the lower esophagus is replaced by tissue similar to the intestinal lining. This change happens after years of acid reflux (GERD). While it is not cancer, Barrett's esophagus increases the risk of developing esophageal cancer if left untreated.
He reviews your acid reflux history, GERD symptoms, lifestyle factors, and risk factors such as obesity, smoking, and family history of esophageal disease.
A thin, flexible endoscope examines the lining of your esophagus. Small tissue samples are taken to look for the presence of Barrett's changes under a microscope.
A small probe measures acid levels in your esophagus over 24 hours to quantify reflux severity and correlate symptoms with acid exposure.
This test evaluates the strength and coordination of esophageal muscles and the function of the lower esophageal sphincter.
An X-ray study that visualizes esophageal shape and motility, helping identify hiatal hernias or strictures.

Barrett's Esophagus is a condition where the normal lining of the esophagus is replaced with cells similar to the lining of the intestine. Dr. Rishi Chadha specializes in diagnosing and managing this condition in Houston.
It is most commonly caused by long-term gastroesophageal reflux disease (GERD). Dr. Chadha evaluates reflux symptoms and recommends screenings if you're at risk.
Most people don't have symptoms beyond GERD signs like heartburn, regurgitation, and chest discomfort. Dr. Chadha may recommend an endoscopy if you have persistent reflux.
No, but it increases the risk of esophageal cancer. Dr. Chadha monitors patients regularly with biopsies and endoscopic surveillance to detect any changes early.
Dr. Chadha performs an upper endoscopy with biopsies to confirm the diagnosis and look for any signs of dysplasia or precancerous changes.
While the damage can't always be reversed, Dr. Chadha provides treatments to control GERD, monitor changes, and prevent cancer progression.
Treatments include proton pump inhibitors (PPIs), lifestyle changes, and endoscopic procedures like radiofrequency ablation in certain cases. Dr. Chadha creates a plan tailored to your needs.
Dr. Chadha will recommend surveillance endoscopy every 3-5 years or more frequently if dysplasia is found, depending on your risk factors.
Avoid spicy foods, alcohol, caffeine, and smoking. Eat smaller meals and avoid lying down after eating. Dr. Chadha offers diet guidance and reflux control tips.
