Reflux esophagitis happens when stomach acid flows back into the esophagus. This acid causes irritation and swelling in the esophageal lining, which over time may lead to pain and damage. The ICD-10 code for reflux esophagitis is K21.0.
Dr. Chadha reviews your symptoms, dietary habits, medication use, and known risk factors to understand your reflux pattern.
A thin, flexible scope with a camera inspects the esophageal lining for inflammation, ulcers, or Barrett's changes.

Pressure sensors evaluate the strength and coordination of esophageal muscles and the lower esophageal sphincter.
You drink a contrast solution while X-rays track its flow, revealing structural abnormalities like strictures or hiatal hernia.
