Acid Reflux and GERD Difference: Understanding the Condition and Its Impact on Health
Acid reflux and Gastroesophageal Reflux Disease (GERD) are common digestive disorders that affect millions of people worldwide. These conditions occur when stomach acid flows back into the esophagus, causing discomfort and potential damage to the esophageal lining.
Understanding the difference between occasional acid reflux and the chronic condition known as GERD is essential for effective management and treatment.
What is Acid Reflux?
Acid reflux, also known as gastroesophageal reflux, occurs when the lower esophageal sphincter (LES)—a ring of muscle at the bottom of the esophagus—relaxes inappropriately, allowing stomach acid and other contents to flow back up into the esophagus (and possibly all the way into the throat and mouth). This backflow, or reflux, of acid and other stomach contents can cause a burning sensation in the chest known as heartburn, along with other symptoms such as regurgitation of food or sour liquid, chest pain, difficulty swallowing, and a sensation of a lump in the throat.
Occasional acid reflux is common and can be triggered by certain foods, beverages, or lifestyle factors, including:- Eating large meals or lying down right after a meal
- Consuming fatty or fried foods, citrus, chocolate, mint, garlic, onions, or spicy foods
- Drinking alcohol, coffee, tea, or carbonated drinks
- Smoking
- Being overweight or pregnant
- Taking certain medications, such as aspirin or ibuprofen
For most people, occasional acid reflux is a mild discomfort that can be managed with lifestyle changes and over-the-counter medications.
What is GERD?
Gastroesophageal Reflux Disease (GERD) is a chronic and more severe form of acid reflux. It occurs when the reflux of stomach contents leads to troublesome symptoms—occurring two or more days per week—that negatively impact the patient’s well-being, or when complications arise. In GERD, the frequent exposure of the esophagus to stomach acid can cause inflammation, irritation, and damage to the esophageal lining, potentially leading to further complications such as:
- Esophagitis: Inflammation of the esophagus, which can cause pain, difficulty swallowing, and bleeding.
- Esophageal Stricture: Narrowing of the esophagus due to scar tissue from repeated exposure to stomach acid, leading to difficulty swallowing.
- Barrett’s Esophagus: A condition where the esophageal lining changes, increasing the risk of developing esophageal cancer.
- Chronic Cough, Asthma, or Laryngitis: GERD can cause or exacerbate respiratory conditions due to the irritation of the airways by acid.
Symptoms of GERD
The symptoms of GERD are similar to those of acid reflux but tend to be more severe and persistent. They can include:
- Heartburn: A burning sensation in the retrosternal area (behind the breastbone).
- Regurgitation: Effortless presence of sour or bitter stomach content in the mouth.
- Chest pain: Especially when lying down or after eating.
- Chronic cough, wheezing
- Hoarseness, burning throat or sore throat
- Feeling of a lump in the throat (globus sensation)
- Bad breath, oral dryness, buccal burning
- Sleep apnea, sleep disturbances
If you frequently experience these symptoms, or ‘alarm symptoms’ such as difficulty swallowing (dysphagia), painful swallowing (odynophagia) of food and liquids, unexplained weight loss, loss of appetite, vomiting, or the presence of red or black stools, it is crucial to seek medical advice for an accurate diagnosis and appropriate treatment plan.
Diagnosis and Treatment
The diagnosis of GERD is typically based on symptoms, medical history, and a physical examination. In some cases, further testing may be required, such as:
- Upper endoscopy: A procedure where a flexible tube with a camera (endoscope) is inserted down the throat to examine the esophagus and stomach.
- pH-impedance monitoring: A test that measures how often stomach acid enters the esophagus and the severity of acid exposure.
- Esophageal manometry: A test that measures the strength and coordination of esophageal muscles.
Treatment for acid reflux and GERD aims to reduce symptoms, heal the esophagus, and prevent complications. Options include:
1. Lifestyle Changes:
- Keep meal sizes small. Consider 4 or 5 small meals instead of 3 large meals during the day.
- Avoid spicy or high-fat foods, alcohol, caffeine, carbonated beverages
- Avoid lying down immediately after eating
- Elevate the head of the bed
- Lose weight if overweight
- Quit smoking
2. Medications:
- Antacids: Provide quick relief by neutralising stomach acid.
- Histamine 2 receptor antagonists (H2 blockers): Reduce the amount of acid the stomach produces.
- Proton Pump Inhibitors (PPIs): More potent than H2 blockers, these medications reduce acid production and promote healing of the esophagus.
- Potassium- competitive acid blockers (P-CABs): A newer class of antisecretory medications, which act faster and last longer than PPIs. They are used in patients with more severe erosive esophagitis and patients with GERD who fail twice-daily PPI treatment.
3. Surgery:
For those who do not respond to medication or lifestyle changes, surgical options such as fundoplication may be considered. This procedure reinforces the lower esophageal sphincter to prevent acid reflux.Conclusion
Acid reflux and GERD are conditions that can significantly impact quality of life if not properly managed. While occasional acid reflux is common and often manageable with lifestyle adjustments, GERD requires more comprehensive treatment to prevent complications and improve symptoms.
If you experience frequent or severe symptoms of acid reflux, it’s important to seek medical advice to ensure you receive the appropriate care and treatment to protect your esophageal health.
