Ulcus (Peptic Ulcer Disease) – A Complete Patient‑Friendly Guide

Overview

Peptic ulcer disease (PUD), commonly called an ulcer or “ulcus,” is a break in the lining of the stomach (gastric ulcer) or the first part of the small intestine, the duodenum (duodenal ulcer). The lesion is usually deeper than a simple erosion and can bleed or perforate if left untreated.

Who it affects: Peptic ulcers can occur at any age but are most common in adults between 30–70 years. Historically, men were diagnosed more often, yet recent data show the gender gap has narrowed, with women now representing ≈ 45 % of cases.

Prevalence: In the United States, an estimated 2–3 % of the population experiences a peptic ulcer each year, amounting to roughly 5–10 million new diagnoses worldwide annually. The condition is less common in low‑income countries where *Helicobacter pylori* infection rates are high but access to diagnostic testing is limited.

Most ulcers heal with appropriate therapy, but untreated disease can lead to serious complications, including bleeding, perforation, and gastric outlet obstruction.

Symptoms

Symptoms can be vague, and some people have “silent” ulcers that cause no pain. When present, they typically develop gradually.

• Burning or gnawing epigastric pain – Often described as a “hunger pain.” It may improve with eating (duodenal ulcer) or worsen after meals (gastric ulcer).
• Regurgitation or sour taste – Acid reflux‑like sensation.
• Nausea or early satiety – Feeling full after a small amount of food.
• Belching and bloating – Frequently reported with gastric ulcers.
• Weight loss – Unintentional loss due to avoidance of food because of pain.
• Dark or tar‑colored stools (melena) – Indicates upper‑GI bleeding.
• Vomiting of blood (hematemesis) – May appear bright red or “coffee‑ground” if partially digested.
• Fatigue or anemia signs – Resulting from chronic blood loss.
• Sudden, severe abdominal pain – May signal perforation (see Emergency Care section).

Causes and Risk Factors

Primary causes

1. Helicobacter pylori infection – The most common cause, accounting for up to 70 % of duodenal and 50 % of gastric ulcers. The bacteria damage the mucosal barrier and provoke inflammation.
2. Non‑steroidal anti‑inflammatory drugs (NSAIDs) – Regular use of ibuprofen, naproxen, aspirin, or COX‑2 inhibitors inhibits prostaglandin production, weakening the stomach’s protective mucus.
3. Excess gastric acid production – Conditions such as Zollinger‑Ellison syndrome increase acid output, overwhelming mucosal defenses.

Additional risk factors

• Smoking – Reduces mucosal blood flow and impairs ulcer healing.
• Heavy alcohol consumption – Irritates the gastric lining and may increase acid secretion.
• Stress (physiologic) – Severe physiological stress (e.g., major surgery, burns, ICU stay) can precipitate “stress ulcers.”
• Caffeine – May increase gastric acidity, though its role as a primary cause is modest.
• Family history – Genetic predisposition to *H. pylori* infection or hyperacidic states.
• Age > 60 years – Age‑related mucosal atrophy and polypharmacy raise risk.

Diagnosis

Diagnosis begins with a detailed history and physical exam, followed by targeted testing.

Non‑invasive tests

• Urea breath test – Detects active *H. pylori* infection; > 95 % sensitivity.
• Stool antigen test – Useful for confirming eradication after therapy.
• Serology – Detects antibodies but cannot differentiate active from past infection; not ideal for diagnosis.

Invasive tests (endoscopy)

Upper gastrointestinal (GI) endoscopy (esophagogastroduodenoscopy, EGD) is the gold standard when:

• Alarm features are present (e.g., bleeding, weight loss, anemia).
• Patients are > 55 years old with new‑onset dyspepsia.
• Initial therapy fails.

During EGD, the physician can:

• Directly visualize ulcers, measure size, and assess for malignant features.
• Obtain biopsies to rule out gastric cancer and test for *H. pylori* (rapid urease test, histology, culture).

Other imaging (if perforation suspected)

• Abdominal X‑ray – May reveal free air under the diaphragm.
• CT scan – More sensitive for detecting perforation, abscess, or penetration.

Treatment Options

Medical therapy

1. Eradication of H. pylori – Triple therapy (proton‑pump inhibitor [PPI] + clarithromycin + amoxicillin or metronidazole) for 10–14 days is standard. Bismuth‑based quadruple therapy is an alternative in areas with high resistance.
2. Proton‑pump inhibitors (PPIs) – Omeprazole, esomeprazole, pantoprazole, etc., reduce acid secretion, promote healing, and are given twice daily for 4–8 weeks.
3. H2‑receptor antagonists – Ranitidine, famotidine – less potent than PPIs; used when PPIs are contraindicated.
4. Protective agents – Sucralfate or misoprostol (a prostaglandin analogue) coat the ulcer and are useful for NSAID‑related ulcers.
5. Discontinuation or substitution of NSAIDs – Switch to acetaminophen or COX‑2‑selective agents if pain control is needed.

Procedural interventions

• Endoscopic hemostasis – For active bleeding ulcers (injection, thermal coagulation, clips).
• Surgical repair – Indicated for perforated ulcers, refractory bleeding, or obstruction; may involve laparoscopic oversewing or partial gastrectomy.
• Endoscopic balloon dilation – Used for chronic gastric outlet obstruction secondary to scarring.

Lifestyle modifications (adjunct to medication)

• Quit smoking – Reduces recurrence by up to 50 %.
• Limit alcohol – < 2 drinks per day for men, < 1 for women.
• Avoid NSAIDs or use the lowest effective dose with gastro‑protective agents.
• Eat smaller, frequent meals rather than large meals.
• Manage stress through relaxation techniques, counseling, or mindfulness.

Living with Ulcus (Peptic Ulcer Disease)

Daily management tips

• Medication adherence – Take PPIs 30 minutes before breakfast and dinner; complete the full course of *H. pylori* therapy even if symptoms improve.
• Track symptoms – Keep a diary noting pain patterns, foods, and medication timing; share with your clinician.
• Dietary guidance – While no single “ulcer diet” exists, most patients feel better avoiding:
  • Very spicy foods
  • Citrus and tomato‑based sauces
  • Chocolate and mint
• Hydration – Adequate water intake helps maintain mucosal health.
• Regular follow‑up – Endoscopic re‑evaluation is usually recommended after 8–12 weeks of therapy in patients with high‑risk features.
• Vaccinations – If you are on chronic PPI therapy, discuss pneumococcal and flu vaccines, as acid suppression may increase infection risk.

Prevention

Most ulcers can be prevented with modest lifestyle changes and prudent medication use.

• Test and treat *H. pylori* – Screening is advised for individuals with a family history of ulcer disease or in regions with > 20 % prevalence.
• Use NSAIDs sparingly – When needed, take the lowest effective dose and add a PPI or misoprostol for protection.
• Quit smoking – Smoking cessation programs improve overall GI health.
• Limit alcohol – Keep intake within recommended guidelines.
• Stress management – Chronic psychological stress may exacerbate acid secretion.
• Maintain a healthy weight – Obesity is linked with increased gastro‑esophageal reflux, which can worsen ulcer symptoms.

Complications

If left untreated, peptic ulcers can lead to serious, sometimes life‑threatening problems.

• Upper gastrointestinal bleeding – Presents as melena or hematemesis; may require transfusion or endoscopic therapy.
• Perforation – A hole in the wall of the stomach or duodenum causing sudden, severe abdominal pain and peritonitis; surgical emergency.
• Gastric outlet obstruction – Scarring narrows the pyloric channel, causing vomiting of undigested food.
• Pyloric stenosis – Similar to obstruction, can lead to chronic malnutrition.
• Increased risk of gastric cancer – Chronic *H. pylori* infection and gastric ulceration are risk factors for adenocarcinoma.

When to Seek Emergency Care

Key Take‑aways

Peptic ulcer disease is common, often caused by *H. pylori* infection or NSAID use, and is highly treatable with antibiotics, acid‑suppressing medication, and lifestyle changes. Early diagnosis and adherence to therapy prevent complications such as bleeding or perforation. Patients should be vigilant for alarm symptoms and seek prompt care when they arise.
