What is Ulcer (Peptic)?
A peptic ulcer is a sore that forms on the lining of the stomach (gastric ulcer), the first part of the small intestine called the duodenum (duodenal ulcer), or, less commonly, the esophagus (oesophagitis ulcer). The ulcer develops when the protective mucous layer that shields the gastrointestinal (GI) tract is damaged, allowing stomach acid and digestive enzymes to erode the tissue.
Peptic ulcers are a type of “peptic disease,” a broad term that includes any condition in which the stomach or duodenal lining is damaged by acid. While most ulcers are benign and heal with proper treatment, they can lead to serious complications such as bleeding, perforation, or gastric outlet obstruction if left untreated.
Common Causes
Several factors can disrupt the balance between aggressive gastric secretions and the mucosal defenses. The most frequent causes are:
- Helicobacter pylori infection – a bacteria that colonises the stomach lining and weakens mucosal protection (≈70% of duodenal and 30% of gastric ulcers).1
- Non‑steroidal anti‑inflammatory drugs (NSAIDs) – ibuprofen, naproxen, aspirin, and selective COX‑2 inhibitors reduce prostaglandin production, compromising the mucous barrier.
- Smoking – nicotine increases gastric acid output and impairs ulcer healing.
- Excessive alcohol consumption – irritates the mucosa and stimulates acid secretion.
- Stress‑related mucosal damage – severe physiologic stress (e.g., major surgery, trauma, burns) can cause “stress ulcers.”
- Zollinger‑Ellison syndrome – a rare tumor (gastrinoma) that secretes high levels of gastrin, leading to hyperacidity.
- Chronic use of corticosteroids – especially when combined with NSAIDs.
- Caffeine‑rich beverages – may increase acid production in susceptible individuals.
- Genetic predisposition – family history of ulcer disease raises risk.
- Radiation therapy to the abdomen – can damage the mucosal lining.
Associated Symptoms
Peptic ulcers often present with a characteristic pattern of discomfort, but symptoms can vary widely. Commonly reported features include:
- Epigastric pain – a burning or gnawing sensation 1–3 hours after a meal or during the night.
- Heartburn or acid reflux – especially in gastric ulcers.
- Bloating and belching.
- Nausea or vomiting – occasional vomiting may contain faint blood (coffee‑ground appearance).
- Loss of appetite and weight loss – due to fear of eating.
- Feeling of fullness (early satiety).
- Dark, tarry stools (melena) – sign of upper GI bleeding.
- Fatigue – secondary to anemia from chronic blood loss.
When to See a Doctor
Although many ulcers respond to over‑the‑counter medication, you should schedule a medical evaluation if you notice any of the following:
- Persistent or worsening abdominal pain lasting more than a few weeks.
- Vomiting blood, or material that looks like coffee grounds.
- Black, tarry stools or any sign of gastrointestinal bleeding.
- Sudden, severe abdominal pain that feels “sharp” or “tearing.”
- Unexplained weight loss or loss of appetite.
- Frequent use of NSAIDs or aspirin (≥2 times per week) for more than a month.
- History of H. pylori infection that has not been treated.
Early consultation helps prevent complications and enables targeted therapy, such as eradication of H. pylori or adjustment of medication regimens.
Diagnosis
Physicians use a combination of history, physical examination, and diagnostic testing to confirm a peptic ulcer.
1. Medical History & Physical Exam
Doctors ask about pain pattern, medication use, alcohol and tobacco habits, and prior infections. On exam, they may palpate the abdomen for tenderness or signs of guarding.
2. Laboratory Tests
- Rapid urease test or stool antigen test for H. pylori – non‑invasive, high sensitivity.
- Serology – less commonly used due to lower accuracy.
- Complete blood count (CBC) – assesses anemia from chronic bleeding.
- Serum gastrin level – ordered when Zollinger‑Ellison syndrome is suspected.
3. Endoscopy (Upper GI Endoscopy)
Considered the gold standard. A flexible tube with a camera visualises the mucosa, allows direct biopsy for H. pylori, and evaluates for malignancy or bleeding.
4. Imaging (when needed)
- Contrast‑enhanced CT scan – helps detect perforation, abscess, or obstruction.
- Upper GI series (barium swallow) – occasionally used if endoscopy is unavailable.
Treatment Options
Therapy aims to heal the ulcer, relieve symptoms, eradicate H. pylori (if present), and prevent recurrence.
1. Medication
- Proton‑pump inhibitors (PPIs) – omeprazole, esomeprazole, pantoprazole; reduce acid production and promote healing.
- H₂‑receptor antagonists – ranitidine (withdrawn in many markets), famotidine; moderate acid suppression.
- Antacids – quick symptom relief but do not heal ulcers.
- Protective agents – sucralfate forms a coating over the ulcer base.
- Antibiotic triple or quadruple therapy for H. pylori – usually a PPI plus clarithromycin and amoxicillin (or metronidazole); duration 10‑14 days. 2
- Cytoprotective drugs – misoprostol (prostanoid analog) particularly for NSAID‑induced ulcers.
2. Lifestyle & Home Measures
- Stop smoking and limit alcohol.
- Reduce or eliminate NSAID use; switch to acetaminophen for pain when possible.
- Eat smaller, more frequent meals; avoid foods that trigger your pain (spicy, fatty, or highly acidic foods).
- Elevate the head of the bed 6‑8 inches to lessen nighttime reflux.
- Manage stress through relaxation techniques (deep breathing, yoga, mindfulness).
3. Surgical Intervention
Rarely required, but indicated for complications such as:
- Perforation (hole in the wall of the stomach or duodenum).
- Uncontrolled bleeding despite endoscopic therapy.
- Obstruction of gastric outlet.
- Suspected malignant ulcer that cannot be ruled out endoscopically.
Prevention Tips
Most peptic ulcers are preventable with simple habit changes and prudent medication use.
- Test and treat H. pylori if you have a history of ulcers or belong to high‑risk groups.
- Use the lowest effective dose of NSAIDs and limit duration; consider a PPI prophylaxis if long‑term NSAID therapy is unavoidable.
- Avoid smoking; nicotine impairs mucosal blood flow and delays healing.
- Limit alcohol intake to ≤1 drink per day for women, ≤2 for men.
- Maintain a balanced diet rich in fruits, vegetables, and fiber; these foods provide antioxidants that protect the gastric lining.
- Manage stress – chronic stress can increase gastric acid secretion.
- Stay up‑to‑date on vaccinations (e.g., for H. pylori‑related gastritis, there is ongoing research on vaccine development).
- Regular medical follow‑up if you have a known ulcer, especially after completing therapy, to confirm healing with repeat endoscopy when indicated.
Emergency Warning Signs
- Sudden, severe abdominal pain that does not improve with rest.
- Vomiting blood (bright red) or material that looks like coffee grounds.
- Black, tarry stools (melena) or bright red blood per rectum.
- Signs of shock: rapid heartbeat, low blood pressure, cold clammy skin, faintness.
- Difficulty breathing or swallowing, which may indicate a perforated ulcer causing peritonitis.
