The Gastritis That Wasn’t

A middle-aged man came with burning upper abdominal discomfort after dinner. Antacids helped briefly—but one detail did not fit.

A clinical reasoning story for medicos and doctors • Educational composite case

A 54-year-old man walked into the clinic complaining of “gas.” For three days he had a burning discomfort in the upper abdomen after meals. He had taken an over-the-counter antacid twice and felt temporary relief.

He denied severe chest pain. No vomiting. No fever. He looked comfortable enough to continue working.

The obvious diagnosis

Dyspepsia seemed reasonable. But during the history, one sentence changed the direction of the consultation:

“Yesterday the same burning started while I was walking quickly to catch a bus. It stopped when I rested.”

That was difficult to explain by gastritis alone. He also had diabetes and hypertension.

The clue that mattered

The discomfort was exertional, reproducible and relieved by rest. An ECG was obtained. It showed ischemic changes, and further evaluation supported acute coronary syndrome rather than simple acidity.

The diagnostic twist

Cardiac ischemia does not always present as dramatic central chest pain. Some patients—especially those with diabetes, older adults and women—may describe pressure, indigestion, breathlessness, unusual fatigue or epigastric discomfort.

Clinical pearls

Take-home message

When “gastritis” behaves like angina, treat the pattern—not the label.
