Fatigue & Low Energy
Overview
Chronic fatigue is a state of persistent or recurrent exhaustion not fully relieved by rest, with reduced energy, unrefreshing sleep, poor memory, muscle aches, and post-exertion malaise. Chinese medicine classifies it under deficiency taxation (xu lao), arising from constitutional weakness, imbalance of work and rest, prolonged illness, dietary irregularity, or excessive emotions that cause deficiency of qi, blood, yin, and yang and dysfunction of the organs—especially the spleen, kidney, heart, and liver.
Pattern differentiation (clinical patterns)
Spleen Qi Deficiency
Fatigue and weak voice with poor appetite and post-meal abdominal bloating, loose stools, sallow face, pale tongue with thin white coating, slow weak pulse.
Fortify the spleen and boost qi; aid transformation and movement.
Kidney Qi Deficiency
Mental and physical fatigue with weak aching lower back/knees, dizziness, tinnitus, poor memory, frequent night urination, cold intolerance or cold limbs, pale tongue with thin coating, deep fine pulse.
Tonify the kidney and boost qi; strengthen the lower back and secure astringency.

Daily care & prevention
Keep regular sleep without excessive bed rest; build aerobic and resistance exercise gradually to avoid post-exertion crashes. Eat a balanced diet with enough protein, vegetables, and fruit, hydrate, manage stress, and pace activities. Moxibustion or massage at Zusanli (ST36), Qihai (CV6), Guanyuan (CV4), Pishu (BL20), and Shenshu (BL23) may support deficiency.
When to seek medical care
Seek evaluation for fatigue with unexplained weight loss, persistent low fever or night sweats, enlarged lymph nodes, chest symptoms, black stools, or low mood with self-harm thoughts, to rule out anemia, thyroid disease, infection, sleep apnea, or depression. Fatigue lasting over six months that severely limits life also warrants systematic assessment.
