TCM Differentiation and Treatment of Childhood Enuresis
Childhood Enuresis: Consolidate the Foundation, Stop Urinary Incontinence
Enuresis, commonly known as "bedwetting," refers to involuntary urination during sleep in children aged three and above, with awareness only upon waking.
Generally, normal infants should gradually gain control over urination after 18 months of age. However, inability to control nighttime urination before age three is still considered a normal physiological phenomenon. If a child over three years old still cannot voluntarily control nocturnal urination, especially if this persists beyond age five, it becomes pathological, as children over three have increasingly developed qi and blood, and organ systems mature, enabling bladder control and expression. Of course, occasional enuresis in school-aged children due to excessive daytime activity, mental fatigue, or drinking large amounts of fluids before bedtime does not fall within the pathological category.
Some children with enuresis have had bedwetting since birth, while others may have been dry for over a year but relapse due to emotional stress or fatigue, persisting until adulthood. Rarely, adults still experience bedwetting. Chronic enuresis can lead to psychological distress, self-esteem issues, negatively affecting mental and physical health, and impairing intellectual and physical development.
According to international surveys, approximately 10–15% of children suffer from enuresis. Domestic data indicate an average incidence rate of about 10.77% among primary school students. Therefore, parents should clearly understand enuresis. If their child has enuresis, they should seek medical evaluation to rule out urinary tract infections, spina bifida (occult or associated with spinal cord herniation), spinal cord injury, epilepsy, or brain developmental abnormalities. Timely treatment is essential when indicated. Notably, the prevalence of occult spina bifida is high among enuretic children, and traditional Chinese medicine has shown good efficacy. For functional enuresis, TCM classifies patients into four types: Kidney Qi Deficiency, Spleen-Pulmonary Qi Deficiency, Liver Channel Damp-Heat, and Heart-Kidney Disharmony.
For children with Kidney Qi Deficiency, nightly bedwetting occurs multiple times, with clear, long urine and mild odor. During cold weather, frequent urination is common. Pale complexion, lack of luster, fatigue, cold limbs, cold sensitivity, or weak legs, slightly below-average intelligence compared to peers, pale tongue with white slippery coating, etc. Treatment: Warm and tonify kidney yang.

Children with enuresis usually do not wake up during the night, so in herbal formulas, tranquilizing and awakening herbs like Lotus Seed, Ephedra, Calamus, and Polygala are often added.
In addition to medication, other methods include acupuncture: select points such as Guanyuan, Qihai, Sanyinjiao, Yinlingquan, Yintang (2–3 points per session, optionally adding Zu Sanli). Hand acupuncture: Night Urination Point (midpoint of the transverse crease of the little finger), retain needles for 15 minutes. Ear acupuncture: Points for Kidney, Bladder, and Subcortex. Or use massage therapy: rub Dan Tian 200 times, massage abdomen for 20 minutes.
Parents should help children develop good habits: regular urination schedule, avoid excessive play during the day to prevent nighttime fatigue and oversleeping, reduce fluid intake in the evening, eat less liquid or soups for dinner. Before bedtime, remind the child to empty the bladder. At the time when the child usually wets the bed, wake them up to urinate. Gradually reduce the frequency of waking until the child can spontaneously void without assistance. Children with enuresis often carry significant psychological burdens, fearing embarrassment and shame. Parents should patiently guide and educate their children, avoiding blame or punishment. Help them overcome shyness and anxiety, build confidence in treatment, and maintain mental and physical well-being. For children with strong self-esteem, parents should keep their condition confidential.
