What Is Gastroesophageal Reflux Disease (GERD)?

Gastroesophageal Reflux Disease (GERD) Services at GHS

What is GERD?

Gastroesophageal Reflux Disease (GERD), commonly called acid reflux disease, is a condition in which stomach contents regularly flow back up into the esophagus. The esophagus is the tube that carries food from your throat to your stomach. Since the esophagus is not designed to handle repeated exposure to stomach acid, ongoing reflux can irritate the lining and lead to symptoms that range from mild heartburn to persistent discomfort and complications over time.

What Is the Difference Between GERD and Acid Reflux?

Many adults experience occasional reflux, especially after a large meal or when lying down soon after eating. GERD is the term providers use when reflux is more persistent or more severe, meaning symptoms keep returning, happen regularly (often two or more times per week), or lead to inflammation or other complications over time.

GERD can also show up in different ways. Some people feel classic heartburn, while others notice nighttime symptoms, throat irritation, or a chronic cough.

What is a Lower Esophageal (Gastroesophageal) Sphincter?

The lower esophageal sphincter (LES) is a circular band of muscle at the bottom of the esophagus. When healthy, it opens to let food into the stomach, then closes tightly to prevent reflux.

A weakened or relaxed LES permits stomach contents to splash back (“reflux”) onto the unprotected lining of the esophagus. Chronic reflux damages the esophageal wall, leading to inflammation, scarring, and even Barrett’s esophagus or cancer if untreated.

Common Symptoms of GERD

Typical Symptoms

Heartburn: Burning pain behind the breastbone, often after meals, and often worse when bending over or lying down
Regurgitation: Sour or bitter-tasting fluid in the throat or mouth
Upper abdominal pain: Pain or discomfort in the upper abdominal, often after eating

Nighttime Symptoms

Ongoing cough, choking, or wheezing when lying flat
Sleep disruption due to burning, coughing, or regurgitation

Less common symptoms (still important)

Trouble swallowing (dysphagia) or a feeling that food is sticking
Hoarseness or laryngitis, frequent throat clearing, or a persistent sore throat
New or worsening asthma symptoms in some patients

If you experience sudden, severe chest pain, call 911 or visit our emergency department to rule out a cardiac event.

Contact a healthcare provider promptly if you have symptoms that may suggest complications or another serious problem, including trouble swallowing, persistent vomiting, unexplained weight loss, or signs of bleeding (vomit that contains blood or looks like coffee grounds, stools that contain blood, or stools that look black and tarry).

Causes & Risk Factors

Hiatal Hernia: Part of the stomach pushes into the chest through the diaphragm
Obesity: Increases abdominal pressure on the LES
Dietary Triggers: Caffeine, peppermint, fatty foods, chocolate, alcohol
Lifestyle Factors: Smoking weakens LES tone; late-night meals worsen reflux
Medications: Some medicines can worsen reflux, including calcium channel blockers, nitrates, anticholinergics, and theophylline

Triggers vary person to person. Some people react strongly to specific foods or larger portions, while others notice symptoms mainly when eating close to bedtime or when reflux occurs at night. Keeping a short symptom log for one to two weeks can help you identify patterns worth changing.

Diagnosing GERD at GHS

Our multidisciplinary team offers a comprehensive evaluation:

Upper Endoscopy (EGD): Visualize the esophageal lining, biopsy if needed
pH Monitoring: Measure acid exposure over 24–96 hours
Esophageal Manometry: Assess LES pressure and esophageal muscle function
Imaging & Blood Tests: Rule out other causes of upper abdominal pain

In many cases, clinicians can begin with a symptom and history review and recommend lifestyle changes or medication to see if symptoms improve. Testing is more likely when symptoms do not improve with initial treatment, when symptoms are atypical, or when warning signs are present, such as trouble swallowing, bleeding, weight loss, vomiting, or anemia.

Treatment Options for GERD

GERD treatment depends on how often symptoms occur, how severe they are, and whether there are signs of irritation or complications.

Lifestyle changes are often a first step. Your provider may recommend weight loss if needed, avoiding meals close to bedtime, and identifying triggers that worsen symptoms.

Elevating your head during sleep can also help. One approach is using a foam wedge or elevating the head of the bed 6–8 inches. Stacking pillows under your head usually isn’t as effective because it can bend your neck instead of lifting your upper body.

Medicines may be used when lifestyle changes are not enough. Over-the-counter options can help with mild symptoms, while prescription medications can reduce acid exposure and allow the esophagus to heal when symptoms are frequent or persistent. Proton pump inhibitors (PPIs) are commonly used for GERD, and your provider can help weigh the benefits and risks based on your health history.

Procedures or surgery may be considered for selected patients, such as those whose symptoms do not improve with medicines and lifestyle changes or those who prefer to avoid long-term medication. Fundoplication is one surgical option used to strengthen the barrier between the stomach and esophagus.

Prevention & Self-Care Tips

Quit Smoking to strengthen LES function
Limit Caffeine & Alcohol
Don’t Eat within 2–3 hours of bedtime
Raise Your Bed Head or use a wedge pillow
Consider Smaller Meals
Avoid Tight Clothing that increases abdominal pressure
Discuss Persistent Symptoms with your provider

Frequently Asked Questions

Q: What’s the difference between GERD and everyday heartburn?
A: Occasional heartburn is common; GERD is diagnosed when symptoms occur twice or more per week or cause complications.

Q: How can I strengthen my lower esophageal sphincter?
A: Weight loss, quitting smoking, and avoiding trigger foods can improve LES tone.

Q: When is GERD a medical emergency?
A: Sudden, severe chest pain—especially with shortness of breath—requires immediate evaluation to rule out a heart attack.

Q: Can GERD cause cough or throat symptoms?
A: Yes. Nighttime reflux can be associated with an ongoing cough, laryngitis, or new or worsening asthma symptoms in some patients.

Q: Do I need an endoscopy for GERD?
A: Not always. Endoscopy is more likely when symptoms are persistent despite treatment or when warning signs are present, such as trouble swallowing, bleeding, weight loss, vomiting, or anemia.
