Ulcus (Peptic Ulcer Disease) – Comprehensive Medical Guide

Overview

Peptic ulcer disease (PUD), commonly referred to as an ulcer or “ulcus,” is a breach in the lining of the stomach, duodenum (first part of the small intestine), or, less frequently, the esophagus. The ulcer creates a pocket of exposed tissue that can bleed or become inflamed.

While anyone can develop an ulcer, the condition is most common in adults aged 30–60 years and affects men slightly more than women. In the United States, an estimated 4–10 million people experience a peptic ulcer each year, and about 10 % of the population will have an ulcer at some point in their life (Mayo Clinic, 2023).

Symptoms

Symptoms can vary from mild to severe and may come and go. Not everyone with an ulcer experiences pain.

• Burning or gnawing pain in the upper abdomen, often 2–3 hours after eating or when the stomach is empty.
• Regurgitation of food or sour liquid (acid reflux).
• Nausea or vomiting; in some cases, vomit may contain blood or look like coffee grounds.
• Loss of appetite and unintended weight loss.
• Bloating, belching, or a feeling of fullness.
• Sudden, severe pain that may indicate perforation (a hole in the wall of the stomach or duodenum).
• Dark or tar‑black stools (melena) – a sign of bleeding in the upper gastrointestinal tract.
• Anemia‑related symptoms such as fatigue, shortness of breath, or dizziness, caused by chronic blood loss.
• Chest discomfort that can mimic heart disease, especially when the ulcer is near the esophagus.

Causes and Risk Factors

Primary Causes

• Helicobacter pylori infection – a spiral‑shaped bacterium that damages the protective mucous layer of the stomach and duodenum. It is responsible for about 60–70 % of duodenal and 30–40 % of gastric ulcers (NIH, 2022).
• Non‑steroidal anti‑inflammatory drugs (NSAIDs) – regular use of ibuprofen, naproxen, aspirin, or prescription NSAIDs interferes with prostaglandin production, reducing the stomach’s ability to protect itself.

Additional Risk Factors

• Smoking – doubles ulcer risk and impairs healing.
• Excessive alcohol consumption – irritates the gastric lining.
• Stressful lifestyles – while stress alone does not cause ulcers, it can worsen symptoms and delay healing.
• Age > 60 years – reduced mucosal blood flow and higher NSAID use.
• Family history of ulcer disease or H. pylori infection.
• Certain medical conditions (e.g., Zollinger‑Ellison syndrome, Crohn’s disease).

Diagnosis

Diagnosis begins with a thorough history and physical exam. Physicians use a combination of the following tests:

Non‑invasive Tests

• Urea breath test – patient drinks a labeled urea solution; H. pylori breaks it down, releasing labeled carbon dioxide detectable in breath. Sensitivity > 95 %.
• Stool antigen test – detects H. pylori proteins in feces.
• Serology – blood test for H. pylori antibodies (less useful for confirming active infection).

Endoscopic Evaluation

• Upper gastrointestinal (GI) endoscopy (esophagogastroduodenoscopy, EGD) – a flexible tube with a camera visualizes the ulcer, allows biopsy for H. pylori or cancer detection, and assesses for bleeding or perforation.
• Indicated for patients with alarm features (bleeding, vomiting blood, weight loss, age > 55 with new symptoms) or when initial therapy fails.

Imaging for Complications

• Abdominal X‑ray or CT scan – used if perforation is suspected (free air under the diaphragm).
• Upper GI series (barium swallow) – less commonly used; may show ulcer crater.

Treatment Options

Effective treatment typically combines medication, lifestyle modification, and, in rare cases, procedures.

Medications

• Proton‑pump inhibitors (PPIs) – omeprazole, esomeprazole, pantoprazole. They suppress acid production, promote healing, and are first‑line for most ulcers.
• Histamine‑2 receptor antagonists (H2 blockers) – ranitidine (now withdrawn in many markets), famotidine. Useful for milder disease or maintenance therapy.
• Antibiotic regimens for H. pylori – usually a triple‑therapy (PPI + clarithromycin + amoxicillin or metronidazole) for 10–14 days, or a quadruple regimen (PPI + bismuth + tetracycline + metronidazole) when resistance is a concern.
• Protective agents – sucralfate or misoprostol (a prostaglandin analogue) can be added for patients who cannot stop NSAIDs.
• Antacids – provide rapid, short‑term symptom relief but do not heal the ulcer.

Procedural Interventions

• Endoscopic hemostasis – clips, cautery, or injection of epinephrine to stop active bleeding.
• Surgery – reserved for perforation, uncontrolled bleeding, or obstruction not manageable endoscopically. Options include simple oversewing of the perforation or partial gastrectomy.

Lifestyle & Dietary Adjustments

• Avoid NSAIDs whenever possible; use acetaminophen for pain.
• Quit smoking – reduces ulcer recurrence by up to 50 %.
• Limit alcohol to ≤ 1 drink/day for women, ≤ 2 drinks/day for men.
• Eat smaller, regular meals; avoid lying down within 2 hours after eating.
• Identify and limit personal trigger foods (spicy, fatty, or highly acidic foods) – evidence is mixed, but many patients feel better with moderation.

Living with Ulcus (Peptic Ulcer Disease)

Managing a chronic ulcer involves a combination of medication adherence, monitoring, and lifestyle habits.

• Medication schedule – take PPIs 30 minutes before breakfast; set alarms if needed.
• Follow‑up testing – a repeat urea breath test or stool antigen test 4 weeks after completing H. pylori therapy to confirm eradication.
• Track symptoms – keep a simple diary (pain intensity, timing, food intake) to discuss with your clinician.
• Stress management – regular exercise, mindfulness, or cognitive‑behavioral therapy can improve overall well‑being and may reduce symptom flare‑ups.
• Vaccinations – for patients on long‑term PPIs, consider hepatitis B vaccination as these drugs can increase susceptibility to certain infections.
• Weight management – maintaining a healthy BMI (18.5–24.9 kg/m²) supports healing and reduces pressure on the abdomen.

Prevention

Most ulcers are preventable with simple measures:

• Test and treat H. pylori infection, especially in high‑prevalence regions or before starting long‑term NSAIDs.
• Use the lowest effective NSAID dose for the shortest duration; consider COX‑2 selective inhibitors (e.g., celecoxib) if NSAID therapy is unavoidable, but still pair with a PPI.
• Adopt a smoke‑free lifestyle.
• Limit alcohol intake.
• Practice safe medication use – never share prescription NSAIDs and read labels for hidden NSAIDs in over‑the‑counter products.
• Incorporate a balanced diet rich in fruits, vegetables, and whole grains, which may help maintain a healthy gastric mucosa.

Complications

If left untreated, peptic ulcers can lead to serious health problems:

• Bleeding (hemorrhage) – the most common complication; may present as melena, hematemesis, or anemia.
• Perforation – a hole in the stomach or duodenal wall causing sudden, severe abdominal pain and peritonitis; requires emergency surgery.
• Gastric outlet obstruction – swelling or scarring blocks the passage of food, leading to vomiting and weight loss.
• Pyloric stenosis – narrowing of the pyloric channel.
• Increased risk of gastric cancer – especially in chronic H. pylori infection or when ulcers are located in the stomach.
