Gastrointestinal problems can be confusing because many conditions share similar symptoms, especially regarding issues related to the stomach and oesophagus.
Among the most common are Gastroesophageal Reflux Disease (GERD) and stomach ulcers. While both conditions cause discomfort, particularly in the upper abdomen, they are fundamentally different in terms of causes, symptoms, and treatments. Let’s explore what sets GERD and stomach ulcers apart and how you can differentiate between the two.
However, if you are facing severe gastrointestinal pains, it is always advisable that you seek immediate medical attention. Our doctor, Dr Ganesh Ramalingam, will be happy to assist you in understanding the cause of any pain and recommend a treatment plan best suited to your condition.
What is Gastroesophageal Reflux Disease (GERD)?
Gastroesophageal Reflux Disease (GERD) occurs when stomach acid frequently flows back into the oesophagus, the tube connecting your mouth and stomach. This backwash, known as acid reflux, irritates the lining of your oesophagus, and can lead to a burning sensation and other symptoms.
Acid reflux is diagnosed as GERD, which is a chronic condition that is diagnosed when acid reflux occurs at least twice a week.
What Causes Gastroesophageal Reflux Disease (GERD)?
GERD is primarily caused by the weakening of the lower oesophagal sphincter (LES), the valve that separates the stomach from the oesophagus. When this muscle weakens or relaxes abnormally, stomach acid can travel upward into the oesophagus. Factors contributing to GERD include:
- Dietary habits: Spicy foods, fatty foods, caffeine, and alcohol can aggravate GERD.
- Obesity: Excess body weight puts pressure on the abdomen, which can force stomach acid upward.
- Pregnancy: The growing uterus can press on the stomach, leading to acid reflux.
- Hiatal hernia: This occurs when part of the stomach pushes through the diaphragm into the chest cavity, disrupting the function of the LES.
What Are the Symptoms of Gastroesophageal Reflux Disease (GERD)?
The main symptom of GERD is heartburn, a burning sensation in the chest that often occurs after eating and may worsen at night. Other symptoms include:
- Regurgitation: A sour or bitter-tasting acid backing up into the throat or mouth.
- Difficulty swallowing (dysphagia).
- Chronic cough or the sensation of a lump in the throat.
- Hoarseness or sore throat: Acid can irritate the vocal cords.
For many people, GERD symptoms worsen when lying down, making nighttime discomfort a frequent issue.
What is a Stomach Ulcer?
A stomach ulcer, also known as a gastric ulcer, is a sore that forms on the stomach lining due to damage caused by stomach acid. Ulcers can also form in the first part of the small intestine, called the duodenum, in which case it is referred to as a duodenal ulcer. Both are classified under peptic ulcer disease.
What Causes Stomach Ulcers?
Unlike GERD, where the focus is on acid reflux, stomach ulcers are primarily caused by an imbalance between stomach acid and the protective lining of the stomach.
Some key causes include:
- Helicobacter pylori infection: This bacterium damages the stomach lining, making it vulnerable to acid.
- Long-term use of NSAIDs (Nonsteroidal Anti-Inflammatory Drugs): Medications like ibuprofen, aspirin, and naproxen can disrupt the stomach’s protective mucus lining, leading to ulcers.
- Smoking and alcohol: Both can exacerbate the damage to the stomach lining and slow the healing process.
- Stress and spicy foods: While not direct causes, these factors can worsen ulcer symptoms.
What Are the Symptoms of Stomach Ulcers?
Stomach ulcers are often described as causing a burning or gnawing pain in the abdomen, particularly when the stomach is empty. Other symptoms include:
- Pain relief when eating: Strangely, for many people, eating or drinking milk temporarily relieves ulcer pain, though symptoms return once digestion resumes.
- Nausea or vomiting: In severe cases, vomiting blood may occur.
- Dark, tarry stools: This is a sign of bleeding in the stomach or intestines.
- Bloating or belching: Ulcers can cause indigestion and excess gas.
GERD vs. Stomach Ulcer: What Are the Key Differences?
While both GERD and stomach ulcers cause discomfort in the upper abdomen, they are quite distinct.
Here’s how you can tell them apart:
Location of the Problem
- GERD affects the oesophagus, the tube that carries food from your mouth to your stomach. The acid from your stomach causes irritation when it rises into the oesophagus.
- Stomach ulcers occur directly in the stomach lining or the upper part of the small intestine (duodenum). The damage is localised to the tissues of the stomach or small intestine.
Nature of the Pain
- GERD: The burning pain of GERD typically occurs in the chest area and is often described as heartburn. This pain may worsen after eating, lying down, or bending over.
- Stomach Ulcer: The pain associated with ulcers tends to be more localised in the abdomen, often just below the rib cage. Unlike GERD, stomach ulcer pain is usually more intense when the stomach is empty, such as between meals or in the middle of the night.
Triggers and Relief
- GERD: Symptoms worsen after eating, especially with fatty or spicy foods, and lying down can exacerbate the problem. Over-the-counter antacids may provide temporary relief.
- Stomach Ulcer: The pain may temporarily improve when eating or drinking, as food can buffer the stomach acid, but symptoms often return as the stomach empties. Antacids can also help, but ulcers require more targeted treatment.
Complications
- GERD: Long-term untreated GERD can lead to inflammation of the oesophagus, oesophagal strictures (narrowing of the oesophagus), or Barrett’s oesophagus, a condition that can increase the risk of oesophagal cancer.
- Stomach Ulcer: Untreated ulcers can lead to bleeding, perforation of the stomach lining, or obstruction of food passing through the digestive tract, all of which are potentially life-threatening.
How Are These Conditions Diagnosed?
Both conditions can be diagnosed using gastroscopy, where a small camera is inserted down the throat to view the oesophagus, stomach, and duodenum.
In GERD, the oesophagus may appear irritated or inflamed. For ulcers, visible sores or inflammation in the stomach lining or small intestine will confirm the diagnosis. Testing for H. pylori is also common when ulcers are suspected.
What Treatment is Available for These Conditions?
GERD treatment often involves lifestyle changes, such as avoiding trigger foods, eating smaller meals, and not lying down after eating. Medications like proton pump inhibitors (PPIs) or H2 blockers reduce acid production. Severe cases may require surgery to tighten the LES.
Stomach ulcers are typically treated with antibiotics (if H. pylori is present) and acid-suppressing medications like PPIs. If the ulcer is caused by NSAIDs, stopping their use is crucial.
Get an Accurate Diagnosis at G&L Surgical
Though GERD and stomach ulcers may share similar symptoms, their causes, complications, and treatments differ significantly. GERD is rooted in acid reflux, primarily affecting the oesophagus, while stomach ulcers stem from damage to the stomach lining.
Understanding these differences can help you identify symptoms and seek appropriate medical care, ensuring long-term digestive health.
