In Emergency Medicine, the evaluation of abdominal pain follows a structured diagnostic reasoning framework: because pain in the abdomen can arise from benign, serious, life-threatening, or extra-abdominal etiologies, clinicians must systematically broaden their differential rather than anchoring on likely causes. This reasoning integrates embryologically-derived pain classification (visceral, parietal, and referred pain), structured history-taking (the OPQRST mnemonic), a stepwise physical examination sequence, and targeted laboratory and imaging modalities selected according to their sensitivity, specificity, and risk trade-offs (e.g., radiation exposure versus operator dependence). The unifying principle is that diagnostic accuracy in undifferentiated abdominal pain depends on maintaining a high index of suspicion across the full spectrum of possible causes, particularly in high-risk populations such as elderly, immunocompromised, or diabetic patients.
