Exercise Intolerance: Definition, Uses, and Clinical Overview
Exercise Intolerance means a reduced ability to perform physical activity at a level that would be expected for a person’s age, fitness, and health. It often shows up as getting unusually short of breath, fatigued, weak, or limited during exertion. It is a symptom and clinical finding, not a single disease. It is commonly used in cardiology, pulmonology, and rehabilitation to describe functional capacity and guide evaluation.
