What Is Gastroesophageal Reflux Disease (GERD)?
Gastroesophageal reflux disease (GERD) occurs when stomach acid flows back into the esophagus, irritating its lining and causing discomfort. Left untreated, it can lead to complications such as esophagitis or Barrett's esophagus.
Dry cough or hoarseness, especially in the morning
How Dr. Scott Diagnoses Gastroesophageal Reflux Disease (GERD)?
Dr. Scott uses a step-by-step approach:
Medical History and Symptom Review
He reviews your reflux episodes, heartburn intensity, epigastric pain timing, diet, medications and other risk factors.
Physical Examination
He examines your chest, abdomen and throat for tenderness, swelling or signs of inflammation.
Endoscopy
A small camera is guided down your throat to directly view the lining of the esophagus and stomach, identifying esophagitis, ulcers or Barrett's changes.
24-Hour pH Monitoring
A thin probe measures acid levels over a full day to quantify reflux episodes and correlate them with your symptoms.
Esophageal Manometry (if needed)
This pressure study evaluates how well your esophageal muscles and lower esophageal sphincter work, ruling out motility disorders.
Treatment
Our Team offers a full range of care for gastroesophageal reflux disease (GERD).
1. Lifestyle and Diet Modifications
Eat smaller, more frequent meals to reduce reflux
Avoid trigger foods like spicy dishes, citrus, chocolate, and caffeine
Refrain from lying down for at least two hours after eating
Elevate the head of your bed by 6-8 inches to minimize nighttime symptoms
Implement weight loss strategies if you're overweight
2. Medications
Antacids (e.g., Tums, Maalox) for quick acid neutralization
H2 blockers (e.g., famotidine) to reduce acid production
Proton pump inhibitors (e.g., omeprazole) for stronger, longer-lasting relief
3. Minimally Invasive or Advanced Procedures
LINX device: a magnetic ring placed around the esophagus to prevent reflux
Transoral Incisionless Fundoplication (TIF): a non-surgical technique to rebuild the esophageal valve

Frequently Asked Questions
What's the difference between GERD and heartburn?
Heartburn is a symptom-a burning sensation in your chest. GERD is a chronic condition defined by frequent heartburn and other reflux-related issues.
How long will I need to take medication?
Most patients use acid-reducing medicine for about 4 to 8 weeks. Dr. Scott will tailor your treatment plan and guide you on when and how to taper off.
Is long-term use of acid blockers safe?
Long-term use of H2 blockers or PPIs can affect vitamin and mineral absorption. We monitor your labs regularly and adjust therapy to keep you safe.
Can I drive after an endoscopy?
No. You will need someone to drive you home after sedation. You can resume normal activities, including driving, the next day.
Does insurance pay for GERD treatment?
Most health plans in Houston cover diagnostic tests and medical or surgical GERD treatments. Our team verifies your benefits before any procedure.
Is the LINX device safe over time?
Yes. Clinical studies show that LINX provides lasting reflux control for years with a low rate of complications.
When will I start to feel better?
Many patients notice relief within a few days of starting medication or making recommended lifestyle changes.
