From the TCM perspective: Enuresis: kidney and bladder failing to secure
Overview
Repeated bedwetting after age five during sleep is usually developmental and inherited, improving with time and never the child's fault. TCM mainly sees immature/deficient kidney-bladder qi failing to secure urine at night, or lung-spleen qi deficiency, occasionally damp-heat.
☯Common patterns (syndrome differentiation)
1
Kidney yang deficiency

Night wetting with cold clear urine, cold limbs, weak lower back and deep sleep, pale tongue
Treatment principle
Warm kidney yang and secure urine
2
Lung-spleen qi deficiency
Key distinguishing signs
Wetting with fatigue, sweat, frequent colds and poor appetite, pale tooth-marked tongue
Treatment principle
Tonify lung-spleen qi
3
Damp-heat pouring downward

4
Fright/anxiety affecting the bladder

Daily self-care
Never punish; reassure the child. Limit evening fluids, void before bed and use a daytime voiding schedule.
Reward dry days, use a waterproof pad, and consider a bedwetting alarm with guidance.
Treat constipation, check urine infection/diabetes, and seek advice if persistent beyond 6-7 years.
When to seek medical help
The following warning signs require prompt medical evaluation — do not rely on self-treatment:
New daytime wetting, intermittent/strained stream or marked urgency.
Excess thirst/urine with weight loss (diabetes).
Fever, back/abdominal pain, painful urination, bloody urine, or wetting after a back injury.
