Fatigue Symptoms

Fatigue Symptoms

Fatigue is a persistent feeling of tiredness or lack of energy that doesn’t improve with rest. Unlike normal tiredness, fatigue can be more severe, long-lasting, and interfere with daily activities, often resulting from physical, mental, or emotional causes. It is a symptom, not a condition, and may indicate underlying health issues.
