What is GERD and how is it treated?

Overview/Introduction: What is GERD?

GERD stands for Gastroesophageal Reflux Disease. It's a digestive disorder that occurs when stomach acid frequently flows back into the esophagus – the tube connecting your mouth and stomach. This backwash (acid reflux) can irritate the lining of your esophagus, causing heartburn and other symptoms. Occasional acid reflux is common, but when it happens frequently and causes persistent symptoms or complications, it's considered GERD.

Symptoms of GERD

Common Symptoms

  • Heartburn: A burning sensation in the chest, usually after eating, that might be worse at night.
  • Regurgitation: The backflow of stomach contents into the mouth or throat, sometimes leaving a sour or bitter taste.
  • Difficulty Swallowing (Dysphagia): Feeling like food is stuck in your throat.

Less Common Symptoms

  • Chronic Cough: Acid reflux can irritate the airways.
  • Laryngitis: Hoarseness or a sore throat.
  • New or Worsening Asthma: GERD can trigger asthma symptoms.
  • Feeling like you have a lump in your throat (Globus sensation)
  • Nausea
  • Dental erosion: Stomach acid can damage tooth enamel.
  • Bad breath

Causes of GERD

Several factors can contribute to GERD:

  • Weak or Relaxed Lower Esophageal Sphincter (LES): The LES is a muscular ring at the bottom of the esophagus that normally closes after food passes through it to the stomach. If the LES relaxes abnormally or weakens, stomach acid can flow back up into the esophagus.
  • Hiatal Hernia: This occurs when part of the stomach bulges up through the diaphragm (the muscle that separates the chest from the abdomen). A hiatal hernia can weaken or disrupt the LES.
  • Delayed Stomach Emptying (Gastroparesis): If the stomach empties slowly, there's more pressure and volume in the stomach, increasing the likelihood of reflux.
  • Excessive Stomach Acid Production: While not the primary cause, producing too much acid can worsen GERD.
  • Obesity: Excess weight can put pressure on the stomach, increasing the risk of reflux.
  • Pregnancy: Hormonal changes and pressure from the growing fetus can contribute to GERD.
  • Smoking: Smoking weakens the LES.
  • Certain Medications: Some medications, such as NSAIDs (nonsteroidal anti-inflammatory drugs), can irritate the esophagus or relax the LES.

Diagnosis of GERD

A doctor will typically diagnose GERD based on your symptoms and a physical exam. In some cases, further testing may be needed to confirm the diagnosis or rule out other conditions. These tests might include:

  • Upper Endoscopy: A thin, flexible tube with a camera is inserted down your throat to examine the esophagus and stomach. A biopsy (tissue sample) may be taken.
  • Ambulatory Acid (pH) Probe Test: A monitor is placed in your esophagus to measure the amount of acid reflux over a period of time, usually 24 hours.
  • Esophageal Manometry: This test measures the pressure and coordination of muscle contractions in your esophagus when you swallow.
  • Barium Swallow: You drink a liquid containing barium, which coats the esophagus and stomach, making them visible on an X-ray.

Important Note: It's crucial to consult a doctor for proper diagnosis. Do not attempt to self-diagnose.

Treatment Options for GERD

The goals of GERD treatment are to relieve symptoms, heal esophageal damage, and prevent complications. Treatment options include:

  • Lifestyle Modifications:

    • Weight Loss: If you're overweight or obese.
    • Elevating the Head of Your Bed: This helps prevent acid from flowing back into your esophagus at night.
    • Eating Smaller, More Frequent Meals: Avoid large meals that can distend the stomach.
    • Avoiding Trigger Foods: Common triggers include fatty foods, spicy foods, chocolate, caffeine, alcohol, and carbonated beverages.
    • Quitting Smoking:
    • Not Lying Down After Eating: Wait at least 2-3 hours after eating before lying down.

  • Medications:

    • Antacids: These neutralize stomach acid and provide quick relief of heartburn.
    • H2 Blockers: These reduce the amount of acid produced by your stomach.
    • Proton Pump Inhibitors (PPIs): These are more potent acid suppressants than H2 blockers.
    • Prokinetics: These help to speed up stomach emptying, but they are less commonly used due to potential side effects.

  • Surgery:

    • Fundoplication: The top part of the stomach (fundus) is wrapped around the lower esophagus to tighten the LES.
    • LINX Device: A ring of magnetic beads is placed around the LES to strengthen it.

Important Note: Dosages and specific medications should only be determined by a doctor.

Prevention of GERD

While you can't completely prevent GERD, you can reduce your risk and manage symptoms by following some of the lifestyle modifications mentioned above. Maintaining a healthy weight, avoiding trigger foods, and not smoking are key preventive measures.

When to See a Doctor

It's important to see a doctor if:

  • You experience frequent or severe heartburn.
  • Over-the-counter medications don't provide relief.
  • You have difficulty swallowing.
  • You experience unexplained weight loss.
  • You have persistent nausea or vomiting.
  • You have symptoms that interfere with your daily life.
  • You have black, tarry stools (which could indicate bleeding).
  • You experience chest pain, especially with shortness of breath or jaw pain (to rule out heart problems).

Complications of GERD

If left untreated or poorly managed, GERD can lead to several complications:

  • Esophagitis: Inflammation of the esophagus.
  • Esophageal Stricture: Narrowing of the esophagus due to scar tissue formation from chronic inflammation.
  • Barrett's Esophagus: A change in the lining of the esophagus that can increase the risk of esophageal cancer.
  • Esophageal Cancer: A rare but serious complication of long-term, untreated GERD.
  • Respiratory Problems: Chronic cough, asthma, and pneumonia.
