Nocturnal Enuresis — Korean Medicine Treatment for Bedwetting After Age 5
Table of Contents
Definition and causes of nocturnal enuresis
Nocturnal enuresis (夜尿症) refers to involuntary nighttime urination occurring two or more times per week after the age of 5. Approximately 15% of all 5-year-old children experience it, with about 15% resolving spontaneously each year — though 1 to 2% continue without treatment until puberty. The causes are multifactorial and may involve insufficient nighttime antidiuretic hormone (ADH) secretion, reduced bladder capacity, sleep arousal disorder, and psychological stress.
Kidney qi deficiency (腎氣不足) and bladder function
Korean medicine teaches that the kidney (腎) governs the two excretions (二便). Children naturally have not yet developed full kidney qi (腎氣), and children with bedwetting in particular suffer from kidney qi deficiency (腎氣不足), which weakens the bladder's holding (固攝) function. The bladder lacks the strength to retain urine, so urination occurs unconsciously during deep sleep.
Chukcheonhwan (縮泉丸) and herbal prescriptions
The representative formula for bedwetting is Chukcheonhwan (縮泉丸). Built on lindera root (烏藥), alpinia fruit (益智仁), and Chinese yam (山藥), it warms the kidney yang (腎陽) and strengthens the bladder's qi-transformation (氣化) function.
- Kidney yang deficiency (腎陽虛) type: add deer antler base and cuscuta seed to Chukcheonhwan to strengthen yang tonification
- Spleen-lung qi deficiency (脾肺氣虛) type: combine with Bojungikgi-tang to lift upper-warmer qi and support the holding function of the lower warmer
- When psychological tension is involved: modified Guibi-tang to settle both heart and spleen (心脾)
Acupuncture and moxibustion
Acupuncture is performed at Guanyuan (CV4, 關元), Zhongji (CV3, 中極), and Sanyinjiao (SP6, 三陰交). Adding indirect moxibustion at Guanyuan warms both the bladder and the kidney simultaneously and enhances the effect. For young children, gentler pediatric acupuncture or intradermal needles are used.
Lifestyle care and emotional support
Limit fluid intake after 6 p.m., and make sure the child voids before bedtime. Above all, do not scold or shame the child. Bedwetting is a physiological phenomenon unrelated to the child's willpower, and psychological stress only worsens it. Be sure to praise generously on dry nights.
