Nocturia / Frequent Night Urination
Overview
Nocturia refers to increased frequency of urination at night (≥2 times) with increased urine volume, affecting sleep. In TCM, the disease is located in the kidney and bladder, closely related to the lung, spleen, and liver. The basic pathogenesis is insecurity of kidney qi and loss of bladder restraint, or spleen deficiency with qi sinking and failure to transform water-dampness, or liver qi stagnation with inhibited water pathways. Common patterns include insecurity of kidney qi, yang deficiency of spleen and kidney, and liver qi stagnation. It is common in the elderly and those with chronic illness, and may also be seen in patients with xiaoke (diabetes) or lin syndrome (urinary tract infection).
Pattern differentiation (clinical patterns)
Insecurity of Kidney Qi
Frequent night urination with post-void dribbling, soreness and weakness of the lower back and knees, fatigue, tinnitus, pale tongue with white coating, and a deep weak pulse.
Tonify the kidney and secure with astringency; reduce urination and stop incontinence.
Yang Deficiency of Spleen and Kidney
Frequent night urination with clear and profuse urine, aversion to cold with cold limbs, cold and painful lower back and knees, pale complexion, loose stools, pale swollen tongue with teeth marks, and a deep slow pulse.
Warm and tonify the spleen and kidney; assist yang to transform qi.
Liver Qi Stagnation
Frequent night urination with urgency, depression or irritability, distension and fullness in the chest and hypochondrium, frequent sighing, pale red tongue with thin white coating, and a wiry pulse.
Soothe the liver and relieve stagnation; free the water pathways.

Daily care & prevention
Reduce fluid intake before bedtime; avoid strong tea, coffee, and diuretic foods. Keep the lower back and abdomen warm; moxibustion at Guanyuan (CV4), Qihai (CV6), and Shenshu (BL23) may be applied. Practice anal sphincter exercises to secure the lower yuan. Diet should be warm and tonifying, with foods such as Chinese yam, Gordon euryale seed, walnut, and mutton. Maintain emotional calm and avoid overexertion. A voiding diary helps assess the condition.
When to seek medical care
If nocturia is accompanied by marked thirst, polydipsia, and weight loss, rule out xiaoke (diabetes). With dysuria, hematuria, or fever, be alert to lin syndrome (urinary tract infection). With difficulty urinating or a thin urine stream, exclude retention of urine (prostatic hyperplasia). With edema or hypertension, check renal function. Elderly men with sudden onset of increased nocturia should seek medical attention promptly.
