Acid Reflux Disease (GERD)

What Is Acid Reflux Disease (GERD)?

Gastroesophageal reflux disease (GERD) is a chronic digestive condition in which stomach acid or bile flows back into the esophagus, the tube connecting your mouth and stomach. This backwash, known as acid reflux, can irritate and inflame the lining of the esophagus, causing a range of uncomfortable symptoms. While occasional acid reflux is common and usually harmless, GERD is diagnosed when reflux occurs more than twice a week or causes significant symptoms that affect your quality of life.

GERD affects an estimated 20% of the adult population in the United States. Without proper management, chronic GERD can lead to serious complications including esophagitis, Barrett's esophagus, strictures, and in rare cases, esophageal cancer.

Common Symptoms

The hallmark symptoms of GERD include:

Heartburn: A burning sensation in the chest, often after eating, that may worsen at night or when lying down
Regurgitation: A sour or bitter taste in the back of the throat caused by acid backing up
Difficulty swallowing (dysphagia): A sensation that food is stuck in your throat or chest
Chest pain: Particularly after meals, which can sometimes mimic cardiac pain
Chronic cough or hoarseness: Especially in the morning, caused by acid irritating the throat and vocal cords
Laryngitis: Inflammation of the voice box due to acid exposure
Worsening or new-onset asthma: Acid reflux can trigger or aggravate asthma symptoms
Disrupted sleep: Nighttime reflux can cause choking sensations and poor sleep quality

Causes and Risk Factors

GERD occurs when the lower esophageal sphincter (LES) — a ring of muscle at the junction of the esophagus and stomach — becomes weakened or relaxes inappropriately, allowing stomach contents to flow back into the esophagus. Several factors can contribute to this condition:

Hiatal hernia: A condition where the upper part of the stomach pushes through the diaphragm, weakening the LES
Obesity: Excess abdominal fat increases pressure on the stomach and LES
Pregnancy: Hormonal changes and increased abdominal pressure can trigger reflux
Smoking: Nicotine relaxes the LES and reduces saliva production, which normally helps neutralize acid
Certain medications: Including antihistamines, calcium channel blockers, sedatives, and some asthma medications
Dietary triggers: Fatty or fried foods, chocolate, caffeine, alcohol, citrus, tomato-based foods, and spicy meals
Connective tissue disorders: Conditions such as scleroderma can affect esophageal function
Delayed gastric emptying: Slower stomach emptying increases the opportunity for reflux

Diagnosis

Dr. Khan uses a comprehensive approach to diagnose GERD, which may include:

Clinical evaluation: A thorough review of your symptoms, medical history, and lifestyle factors
Upper endoscopy (EGD): A procedure using a thin, flexible scope to visually examine the esophagus and stomach lining, allowing detection of inflammation, ulcers, or Barrett's esophagus
Ambulatory acid (pH) probe test: A monitor placed in the esophagus to measure acid levels over 24 to 48 hours
Esophageal manometry: A test that measures the rhythmic muscle contractions in the esophagus and evaluates LES function
Barium swallow (esophagram): An X-ray study that helps visualize the shape and condition of the upper digestive tract

Treatment Options

Treatment for GERD is tailored to the severity of your symptoms and may include a combination of the following approaches:

Lifestyle Modifications

Elevate the head of your bed by 6 to 8 inches
Avoid eating within 2 to 3 hours of bedtime
Maintain a healthy weight through diet and exercise
Quit smoking and limit alcohol consumption
Eat smaller, more frequent meals instead of large meals
Avoid known trigger foods and beverages
Wear loose-fitting clothing that does not compress the abdomen

Medications

Antacids: Over-the-counter options that provide quick, short-term relief by neutralizing stomach acid
H2 receptor blockers: Medications such as famotidine that reduce acid production
Proton pump inhibitors (PPIs): Stronger acid-suppressing medications (omeprazole, esomeprazole, pantoprazole) that allow the esophagus to heal
Prokinetics: Medications that help the stomach empty faster, reducing the window for reflux

Surgical and Procedural Options

For patients who do not respond adequately to lifestyle changes and medications, surgical interventions may be considered:

Fundoplication: A surgical procedure that reinforces the LES by wrapping the top of the stomach around the lower esophagus
LINX device: A ring of tiny magnetic beads placed around the LES to prevent acid reflux while still allowing food to pass
Transoral incisionless fundoplication (TIF): A minimally invasive procedure performed through the mouth to reconstruct the valve between the esophagus and stomach

Potential Complications

If left untreated, chronic GERD can lead to several serious complications:

Esophagitis: Chronic inflammation and damage to the esophageal lining
Esophageal stricture: Narrowing of the esophagus due to scar tissue formation, causing difficulty swallowing
Barrett's esophagus: A precancerous condition in which the cells lining the lower esophagus undergo abnormal changes
Esophageal adenocarcinoma: A rare but serious cancer that can develop from Barrett's esophagus
Respiratory problems: Chronic aspiration of acid can worsen asthma and cause recurrent pneumonia

When to See a Doctor

You should schedule an appointment with a gastroenterologist if you experience:

Heartburn or acid reflux symptoms more than twice per week
Difficulty swallowing or a persistent feeling of food being stuck
Unexplained weight loss
Persistent nausea or vomiting
Chest pain (after ruling out cardiac causes)
Symptoms that do not improve with over-the-counter medications
A chronic cough, hoarseness, or sore throat that does not resolve

Early diagnosis and treatment of GERD can prevent complications and significantly improve your quality of life. Dr. Amber Khan at GastroCares provides expert evaluation and personalized treatment plans for patients with acid reflux disease.
