What is fatigue?

Fatigue is persistent tiredness or low energy that does not improve adequately with rest.

What is fatigue?

Fatigue is an ongoing sense of exhaustion that limits your ability to work, study, or enjoy daily activities. Unlike ordinary sleepiness, it may persist even after adequate rest.

Chronic fatigue can stem from physical illness, mental health conditions, sleep disorders, or lifestyle factors. Identifying the pattern and duration helps guide appropriate care.

What causes fatigue?

Physical causes include anemia, thyroid disease, diabetes, chronic infections, heart or lung conditions, and inflammatory disorders. Medications and poor sleep quality also contribute.

Mental health factors such as stress, anxiety, and depression frequently cause fatigue. Addressing both physical and emotional health is often necessary for improvement.

When fatigue needs medical evaluation

Consult a doctor if fatigue lasts several weeks, is severe enough to limit daily function, or occurs with unexplained weight change, fever, night sweats, or mood changes.

A general physician can perform an initial assessment and coordinate further care if a specialist opinion is needed.

When to seek medical care

Seek care if fatigue persists beyond two to three weeks, significantly limits daily activities, or is accompanied by fever, weight loss, chest pain, or mood changes.

Which doctor treats fatigue?

For fatigue, a general physician is often the appropriate starting point. They can examine you, order relevant tests, and refer to another specialist if needed. View available doctors.
