Fatigue

Fatigue is a common medical symptom defined as an overwhelming sense of tiredness, weakness, or exhaustion that can be physical, mental, or a combination of both. It is distinct from merely feeling sleepy or drowsy. From a medical perspective, fatigue is often considered a non-specific symptom because it can arise from various causes, ranging from lifestyle factors such as poor sleep patterns and inadequate nutrition to more serious medical conditions like anemia, thyroid disorders, sleep apnea, and chronic diseases including diabetes, heart disease, and multiple sclerosis. Acute fatigue might result from high-intensity physical activity or stress, whereas chronic fatigue lasts longer and may require medical evaluation to determine the underlying cause.

Clinically, fatigue is evaluated in context with other symptoms to ascertain its etiology. Doctors may conduct physical examinations, review medical history, and order laboratory tests to rule out hormonal imbalances, infections, or nutritional deficiencies. Treatment for fatigue is tailored to its root cause and may involve lifestyle modifications such as improved diet, exercise, and sleep hygiene; psychological support like counseling or therapy; and medical management for specific disorders. In some cases, particularly when associated with conditions like chronic fatigue syndrome, the cause may be less understood, making management more complex and requiring a multifaceted approach.
