When Fatigue Is More Than Everyday Tiredness
Patients describe fatigue in different ways. You may feel tired even after sleeping, wake without feeling restored, lose energy partway through the day or feel that you cannot keep up with your usual responsibilities. Fatigue may occur with brain fog, difficulty concentrating, low motivation, disrupted sleep, mood changes, headaches or a reduced tolerance for stress.
Short-term tiredness may have an obvious explanation, such as missed sleep, a demanding week or a brief illness, and may improve with appropriate rest. A more detailed assessment may be helpful when fatigue persists, progressively worsens, interferes with daily life, remains unexplained or appears with other changes in your health.
Persistent fatigue should not be reduced to weight, willpower or the assumption that you simply need to try harder. The assessment considers what may be using energy, what may be interfering with restoration and whether medical investigation or another healthcare professional is needed.
Important safety note: Sudden, severe, progressive or rapidly worsening fatigue – particularly with chest pain, shortness of breath, fainting or loss of consciousness, significant bleeding, unexplained weight change, severe vomiting or another urgent concern – requires appropriate medical assessment. Call 911 or go to the nearest emergency department when there is an immediate danger.
