Peptic Ulcer Disease Manifestations

Q: What are the complications of peptic ulcer disease?

The main complications include: Hemorrhage — arises from eroded vessels, leading to hematemesis and melena.Perforation — characterized by sudden 'dagger-like' abdominal pain and the development of peritonitis.Penetration — a variant of perforation where the ulcer erodes into an adjacent organ, using its wall as the ulcer base.Pyloric stenosis (scarring pyloric obstruction) — when decompensated, it can lead to hypochloremic uremia.Malignant transformation — malignant degeneration of the ulcer.

Peptic ulcer disease manifests with a distinct symptom complex dominated by epigastric pain. The timing, character, and associated dyspeptic symptoms strictly depend on the anatomical location of the ulcer—whether in the stomach or the duodenal bulb.

Main symptomEpigastric pain strictly linked to meal timing.

Late painSpecific for duodenal involvement (1.5–3 hours postprandial).

PalpationLocalized epigastric tenderness, occasionally with muscle guarding.

Autonomic signsTachycardia and hypotension against a background of generalized weakness.

Clinical Presentation of Gastric Ulcer

Gastric mucosal lesions have several specific features. The dominant sign is epigastric pain, the character and onset of which are directly determined by the topography of the defect.

Cardia and posterior wall: This localization is typified by 'early pain', which occurs almost immediately after eating. Pain is often projected to the retrosternal area, requiring careful differential diagnosis. It may also radiate to the left shoulder.
Lesser curvature: Pain onset is somewhat delayed, with discomfort and pain appearing 15 to 60 minutes postprandial.

In addition to pain, the condition is accompanied by pronounced dyspeptic symptoms, including persistent nausea, heartburn, and eructation (belching of air or food). Constipation is also common.

Features of Duodenal Ulcer

When the process localizes to the duodenum, epigastric pain predominates in the vast majority (about 75%) of patients. However, the pain rhythm differs radically from gastric ulcers.

'Late pain' — develops 1.5–3 hours after a meal.
'Hunger pain' — occurs on an empty stomach and drives the patient to seek food.
'Night pain' — awakens the patient during the night.

A critical diagnostic criterion is that eating relieves the pain of a duodenal ulcer or significantly eases the patient's condition.

Another striking clinical marker is vomiting, which develops at the height of the pain episode and brings the patient clear relief, substantially reducing pain intensity. Common dyspeptic complaints include bloating, heartburn, eructation, and frequent constipation.

Physical examination reveals tenderness upon palpation of the epigastric region. In some cases, involuntary abdominal muscle guarding (défense musculaire) is present.

Asthenovegetative Syndrome

Regardless of ulcer location, a prolonged course of the disease depletes nervous system reserves, manifesting as asthenovegetative syndrome, which significantly reduces the patient's quality of life.

Patients complain of pronounced general weakness and progressive decline in work capacity. Regarding the cardiovascular system, autonomic imbalance presents as a tendency toward tachycardia and arterial hypotension.

Mnemonic

'Early food = stomach, hungry night = duodenum.' In gastric ulcers, pain starts almost immediately after eating (or within an hour), whereas in duodenal lesions, the patient suffers from night and hunger pains that miraculously subside after a snack.

Frequently asked questions

What are the complications of peptic ulcer disease?

The main complications include:

Hemorrhage — arises from eroded vessels, leading to hematemesis and melena.
Perforation — characterized by sudden 'dagger-like' abdominal pain and the development of peritonitis.
Penetration — a variant of perforation where the ulcer erodes into an adjacent organ, using its wall as the ulcer base.
Pyloric stenosis (scarring pyloric obstruction) — when decompensated, it can lead to hypochloremic uremia.
Malignant transformation — malignant degeneration of the ulcer.

How does pain differ between a cardiac ulcer and a lesser curvature ulcer?

With a cardiac ulcer, pain appears immediately after eating and may radiate to the left shoulder. With a lesser curvature lesion, pain is delayed and starts 15–60 minutes later.

What is the role of vomiting in duodenal ulcers?

Vomiting occurs at the peak of pain. Its key feature is that it brings the patient noticeable relief and reduces the intensity of the pain syndrome.

What is *défense musculaire* in the context of peptic ulcer disease?

It is reflexive abdominal muscle guarding that may be detected during abdominal palpation in patients with duodenal ulcers.
