GERD Acid Reflux: Symptoms, Complications, and Treatment

 

GERD Vs Acid Reflux

GERD and acid reflux are two terms that are often used interchangeably. But they are not the same, acid reflux is the symptom or event, while GERD is the chronic disease characterised by recurrent acid reflux episodes. The features that clearly distinguish between the two conditions are:

What Are the Symptoms of GERD?

The GERD symptoms can vary widely in intensity and presentation. Recognising these indicators is the first step towards an accurate diagnosis and effective management of this condition.

Typical Symptoms

GERD can present with a range of symptoms that vary in severity and frequency. Some of the most common signs include:

• Heartburn- A burning sensation in your chest, often after eating, that might worsen at night or when lying down

• Regurgitation- Sour liquid or food coming back up into your throat or mouth (GERD related acid reflux)

• Chest pain- Non-cardiac chest discomfort

• Dysphagia- Difficulty swallowing

Atypical Symptoms

In addition to the classic symptoms, GERD can also cause less obvious or atypical symptoms that affect the throat, respiratory system, and oral health, often making diagnosis more challenging. These may include:

• Chronic cough or hoarseness

• Laryngitis

• New or worsening asthma

• Disrupted sleep due to reflux

• Erosion of tooth enamel

What Causes GERD?

GERD occurs when the lower esophageal sphincter (LES), the muscle that prevents stomach contents from flowing back into the esophagus, becomes weak or relaxes abnormally, allowing stomach acid to reflux into the esophagus. This causes irritation and discomfort. Common factors contributing to GERD related acid reflux include:

• Obesity– Increased abdominal pressure promotes acid reflux.

• Hiatal hernia– Affects the normal function of the LES.

• Pregnancy– Hormonal changes and abdominal pressure can trigger reflux.

• Smoking– Weakens the LES and reduces the body's ability to clear acid.

• Trigger foods and drinks– Fatty and fried foods, caffeine, alcohol, chocolate, peppermint, citrus fruits, and tomatoes can worsen reflux.

• Certain medications– Some blood pressure medicines, asthma treatments, and pain relievers may increase the risk of GERD.

What Happens if GERD Is Left Untreated?

Ignoring persistent GERD symptoms can lead to serious complications. Prevention and early management are key to reducing symptoms, preventing complications, and maintaining long-term digestive health. Untreated GERD can lead to:

• Esophagitis- Chronic exposure to stomach acid can inflame the lining of the esophagus, causing pain, irritation, bleeding, or the formation of ulcers.

• Esophageal stricture- Repeated acid damage can lead to scar tissue formation, narrowing the esophagus and making swallowing difficult or uncomfortable.

• Barrett's Esophagus- Long-term GERD can cause abnormal changes in the cells lining the lower esophagus, increasing the risk of esophageal cancer and requiring regular monitoring.

• Respiratory problems- Acid reflux can irritate the airways and lungs, contributing to chronic cough, worsening asthma symptoms, recurrent throat irritation, or even aspiration pneumonia.

How Is GERD Diagnosed?

To accurately diagnose GERD and determine its severity, gastroenterologists use a combination of clinical evaluation and specialised diagnostic tests.

• Patient history and symptom assessment- The diagnostic process begins with a detailed discussion of your symptoms, including their frequency, severity, triggers, and impact on daily life. Your medical history, lifestyle habits, and response to previous treatments are also evaluated.

• Upper endoscopy- An upper endoscopy involves passing a thin, flexible tube with a camera through the mouth to examine the stomach, and upper part of the small intestine (duodenum). This procedure helps identify inflammation, ulcers, strictures, Barrett’s esophagus, or other abnormalities.

• Ambulatory acid (pH) monitoring- This test measures the amount and frequency of acid reflux over a 24-48-hour period. A small probe or wireless capsule is used to monitor acid exposure in the esophagus, helping confirm a diagnosis of GERD and correlate reflux episodes with symptoms.

• Esophageal manometry- Esophageal manometry evaluates the strength and coordination of the muscles in the esophagus, including the lower esophageal sphincter (LES). It helps identify motility disorders that may contribute to swallowing difficulties or reflux symptoms.

How Is GERD Treated?

With proper treatment/management, over 80% of patients find significant relief. A comprehensive GERD treatment plan is tailored for an effective solution. This essentially involves:

• Lifestyle management- Maintaining a healthy weight, avoiding trigger foods, elevating the head of the bed, not lying down immediately after meals, and quitting smoking can help reduce reflux symptoms.

• Medication therapy- Acid-reducing medications help control stomach acid, relieve symptoms, and promote healing of the esophagus..

• Surgical and endoscopic procedures- For patients who do not respond to medications, minimally invasive procedures can strengthen the lower esophageal sphincter (LES) and reduce acid reflux.

Care Essentials

Effective management of GERD goes beyond medication. Adopting healthy lifestyle habits and following recommended care measures can help control symptoms, prevent complications, and improve overall quality of life. You should:

• Eat smaller, frequent meals

• Maintain a healthy weight

• Should not consume trigger foods (fatty foods, chocolate, caffeine, alcohol, spicy foods)

• Elevate the head of the bed by 6-8 inches

• Avoid smoking or using tobacco products

• Wear loose-fitting clothing

• Abstain from lying down immediately after meals

• Stay upright 2-3 hours after eating

• Never ignore persistent GERD symptoms
