What Is Reflux Esophagitis?
Reflux esophagitis occurs when acidic stomach contents flow back into the esophagus, irritating and inflaming its lining. Symptoms can range from occasional heartburn to severe pain and swallowing difficulties. (ICD-10: K21.0)
Common Causes and Risk Factors
Hiatal hernia: Part of the stomach pushes up into the chest cavity.
Obesity or excess abdominal weight: Increases pressure on the stomach.
Smoking and alcohol use: Weaken the lower esophageal sphincter.
Trigger foods: Spicy, greasy, chocolate, citrus or acidic items.
Pregnancy: Hormonal changes and fetal pressure on the abdomen.
Signs and Symptoms
Burning sensation (heartburn) after meals or when reclining.
Regurgitation of acid or bitter taste in the throat/mouth.
Pain or difficulty swallowing (dysphagia).
Chest pain mimicking cardiac issues.
Chronic cough, hoarseness or sore throat due to acid irritation.
How Dr. Scott Diagnoses Reflux Esophagitis?
Dr. Scott uses a step-by-step approach:
Medical History and Exam
He reviews your symptom patterns (heartburn, epigastric pain, swallowing issues), lifestyle factors (diet, weight, smoking, alcohol) and risk factors (hiatal hernia, pregnancy).
Upper Endoscopy (EGD)
A thin, flexible camera inspects the esophageal lining for inflammation, erosions or Barrett's changes.
24-Hour Esophageal pH Monitoring
Records acid exposure in your esophagus over a full day to quantify reflux severity.
Barium Swallow X-Ray
Visualizes structural issues-like hiatal hernia, strictures or motility problems-as you swallow contrast.
Esophageal Manometry
Measures muscle contractions and pressure along the esophagus to assess motility and sphincter function.
Treatment
Our Team offers a full range of care for reflux esophagitis.
1. Lifestyle and Diet Changes
Eat smaller, more frequent meals and avoid late‐night eating
Avoid trigger foods such as citrus, coffee, chocolate, and spicy dishes
Elevate the head of your bed 6-8 inches to reduce nighttime reflux
Maintain a healthy weight through regular exercise
Quit smoking and limit alcohol intake
2. Medications
Antacids for quick relief of mild symptoms
H2 blockers to reduce stomach acid production for several hours
Proton Pump Inhibitors (PPIs) for stronger, guideline-based acid suppression
Prokinetics to speed gastric emptying and minimize reflux episodes
3. Minimally Invasive and Advanced Procedures
Endoscopic fundoplication to tighten the gastroesophageal valve without large incisions
LINX device: a magnetic ring placed around the esophagus to prevent acid backflow
Laparoscopic Nissen fundoplication: keyhole surgery to reinforce the lower esophageal sphincter

Frequently Asked Questions
What is the ICD-10 code for reflux esophagitis?
It's K21.0.
Can diet alone control reflux esophagitis?
Diet helps, but many people also need medicine or other treatments to manage symptoms effectively.
How long do PPIs take to work?
Most patients feel relief within 1-2 weeks, though full healing of the esophagus lining can take longer.
Are endoscopic treatments safe?
Yes. Endoscopic procedures are minimally invasive, have a low risk of complications, and often offer quick recovery.
How should I prepare for an endoscopy?
Do not eat or drink for 6-8 hours before the procedure. Our team will provide detailed prep instructions.
Will my insurance cover treatment?
Most insurance plans cover diagnostic tests and reflux treatments. We assist with authorizations and paperwork.
Can stress cause reflux?
Stress doesn't directly cause reflux, but it can worsen symptoms. Relaxation techniques and lifestyle changes can help.
