- Fatigue lasting for weeks, getting worse or affecting work and daily function deserves a closer look.
- Sleep loss and stress are common causes, but anaemia, thyroid problems, infection, diabetes, mood conditions, medicines and other illnesses can also contribute.
- Do not assume fatigue is a TCM “deficiency” before important conventional causes have been considered.
Separate sleepiness from fatigue
Sleepiness means a strong tendency to fall asleep; fatigue is a broader sense of low physical or mental energy. They can overlap, but the distinction helps. Someone who falls asleep unintentionally may need a sleep disorder assessment, while someone who feels exhausted despite adequate alertness may need a different review.
Look at duration and function
A few demanding days can explain temporary tiredness. More concern is warranted when fatigue lasts several weeks, progressively worsens, repeatedly stops you from exercising or working, or makes routine tasks unusually difficult. Note whether it began after an infection, travel, a major stressor, heavy menstrual bleeding or a change in medicine.
Common contributors are often mixed
Irregular sleep, long work hours, low activity, under-eating, dehydration and emotional strain can all contribute. Medical causes can include iron-deficiency anaemia, thyroid disease, diabetes, infection, sleep apnoea and other conditions. Some antihistamines, pain medicines, sleep medicines and other prescriptions can also cause drowsiness or fatigue.
Food and supplements should be targeted
Eating regular balanced meals is sensible, but taking iron, high-dose vitamins or “energy” supplements without knowing whether you need them is less useful. Excess iron can be harmful, and supplements may interact with medicines. If blood tests are appropriate, they are more informative than guessing.
Red flags need prompt assessment
Seek medical care sooner for fatigue with chest pain, severe breathlessness, fainting, new neurological weakness, black or bloody stools, persistent fever, major unplanned weight loss, marked paleness, rapidly worsening function or thoughts of self-harm. Sudden severe symptoms require urgent care.
Where TCM may fit
A TCM consultation may explore sleep, appetite, digestion, stress, menstrual history and daily routine. This can complement conventional care when serious causes have been considered. Share blood-test results, diagnoses and medicines with the practitioner, and avoid treatments that require stopping prescribed therapy.
Build a two-week fatigue record
Track sleep duration, caffeine, meals, exercise, menstrual bleeding if relevant, stress level and the time of day fatigue is worst. Also note breathlessness, palpitations, dizziness, fever, weight change or snoring. A simple record gives a doctor or TCM practitioner more useful context than the word “tired” alone.
