Gastroesophageal Reflux Disease, commonly referred to as GERD, is one of the most frequent digestive disorders worldwide. It occurs when acidic stomach contents repeatedly flow back (reflux) into the esophagus, the tube connecting the mouth to the stomach. Over time, this acidic exposure damages the esophageal lining, leading to inflammation, pain, and potentially serious complications such as Barrett’s esophagus or even esophageal cancer.
Although occasional acid reflux is common, GERD refers to a chronic, more severe form that requires lifestyle modifications, medical treatment, and sometimes surgery.
Pathophysiology of GERD
The digestive system is designed with a special valve — the Lower Esophageal Sphincter (LES) — that opens to let food enter the stomach and closes to prevent reflux. In GERD, this LES becomes weakened or damaged, allowing acid and partially digested food to flow backward into the esophagus.
Persistent acid reflux leads to:
- Esophagitis (inflammation of the esophagus)
- Ulcerations in the esophageal lining
- Barrett’s esophagus (precancerous changes in cells)
- Higher risk of esophageal adenocarcinoma
If left untreated, chronic GERD can cause permanent esophageal damage.

Signs and Symptoms of GERD
GERD presents with a variety of symptoms, ranging from mild to severe. Common ones include:
- Heartburn (Dyspepsia) – A burning sensation behind the breastbone, often worse after eating or when lying down.
- Regurgitation – Sour or bitter-tasting acid backing up into the throat or mouth.
- Chest Pain – Often mistaken for cardiac pain; requires careful evaluation.
- Dysphagia – Difficulty swallowing due to esophageal inflammation or narrowing.
- Worsening Pain When Lying Down – Gravity no longer helps keep stomach contents in place.
- Chronic Cough, Hoarseness, or Sore Throat – Caused by acid irritation of the throat and vocal cords.
- Asthma-like Symptoms – GERD can worsen asthma or cause respiratory issues.
Causes and Risk Factors
GERD develops when the LES fails to function properly. Several factors contribute to this weakness:
Lifestyle and Dietary Factors
- Fried foods (e.g., fries, fried chicken)
- Fatty foods – A low-fat diet is preferable.
- Citrus fruits – Oranges, lemons, grapefruit (acidic in nature)
- Dairy products – Milk, cheese, cream
- Chocolate
- Peppermint or Spearmint – Relax LES muscle
- Caffeine – Coffee, tea, energy drinks
- Alcohol
- Smoking and tobacco use
Medical Risk Factors
- Obesity (BMI > 30)
- Hiatal hernia
- Pregnancy – Hormonal changes and abdominal pressure
- Stress
- Connective tissue disorders (e.g., scleroderma)
Patient Education and Lifestyle Modifications
Lifestyle changes are the first line of defense against GERD. Patients should:
- Avoid trigger foods (fried, fatty, acidic, chocolate, caffeine, alcohol).
- Eat small, frequent meals instead of large ones.
- Avoid lying down for at least 3 hours after meals.
- Sit upright after eating to use gravity against reflux.
- Elevate the head of the bed at night.
- Quit smoking and avoid alcohol.
- Maintain a healthy weight.
Pharmacological Treatment for GERD
Medications aim to reduce stomach acid, heal the esophagus, and prevent further damage.
| Drug Class | Examples | Action |
|---|---|---|
| Antacids | Calcium carbonate, magnesium hydroxide | Neutralize stomach acid for quick relief |
| H2 Receptor Blockers | Ranitidine (withdrawn in some markets), famotidine | Reduce acid production |
| Proton Pump Inhibitors (PPIs) | Omeprazole, esomeprazole, pantoprazole | Most effective acid suppression; promote healing |
| Prokinetic Agents | Metoclopramide | Improve gastric emptying and LES tone (less common use) |
Diagnostic Procedures
Physicians may recommend tests if GERD symptoms persist despite treatment.
- Upper Gastrointestinal Endoscopy (EGD) – Direct visualization of the esophagus and stomach lining to detect inflammation, ulcers, or Barrett’s esophagus.
- Esophagogastroduodenoscopy (EGD) – Biopsies may be taken for cancer screening.
- pH Monitoring – Measures acid exposure in the esophagus over 24 hours.
- Manometry – Tests LES pressure and esophageal muscle function.
Complications: Peritonitis Warning Signs
In rare cases, GERD-related ulcers can perforate, leading to peritonitis — a surgical emergency.
Report to your healthcare provider immediately if you experience:
- Fever > 100.3°F
- Severe abdominal pain with board-like rigidity
- Rebound tenderness
- Rapid heart rate and breathing
- Restlessness
Surgical Treatment Options
Surgery is considered for patients who:
- Have persistent symptoms despite medication
- Cannot tolerate medications
- Develop complications like severe esophagitis or Barrett’s esophagus
1. Stretta Procedure – Uses radiofrequency energy to strengthen LES muscles.
2. Fundoplication – The upper stomach (fundus) is wrapped around the esophagus to reinforce the LES and prevent reflux.
Saunder’s NCLEX Tip
When educating GERD patients, always stress trigger food avoidance:
- Coffee
- Chocolate
- Peppermint
- Fried chicken

Frequently Asked Questions (FAQs)
Q1: Is GERD the same as acid reflux?
No. Acid reflux is occasional backflow of stomach acid; GERD is a chronic, more severe condition with frequent symptoms.
Q2: Can GERD cause cancer?
Yes, chronic untreated GERD can lead to Barrett’s esophagus, which increases the risk of esophageal cancer.
Q3: What foods should I avoid with GERD?
Fried foods, fatty foods, citrus, chocolate, caffeine, peppermint, alcohol, and dairy are common triggers.
Q4: How is GERD diagnosed?
Through clinical evaluation and tests like endoscopy, pH monitoring, and manometry.
Q5: Is surgery safe for GERD?
Yes, surgical options like fundoplication have high success rates for patients who fail medical management.
