Chronic Kidney Disease (Adjunct)
Overview
Chronic kidney disease falls under the TCM categories of 'edema' (shui zhong), 'guan ge' (dysuria and vomiting), and 'consumption' (xu lao). The disease is located in the kidney and involves the spleen, lung, and liver. Its pathogenesis is root deficiency with branch excess: spleen-kidney yang deficiency is the root, while damp-turbidity, blood stasis, and water-toxin are the branches. Clinically it presents with edema, fatigue, poor appetite, nausea, oliguria or nocturia. Early stages often show spleen-kidney qi deficiency; later stages show internal accumulation of turbid toxin, which may cloud the clear orifices or invade the pericardium. Treatment follows the principle of supporting the upright and dispelling pathogenic factors—warming and tonifying the spleen and kidney, transforming dampness and descending turbidity, invigorating blood and promoting diuresis—to relieve symptoms and slow progression.
Pattern differentiation (clinical patterns)
Spleen-Kidney Yang Deficiency
Generalized edema, worse below the waist, pitting and slow to rebound; pale lusterless complexion, aversion to cold with cold limbs, soreness and weakness of the lower back and knees, fatigue and lack of strength, poor appetite with loose stools, scanty urine, pale swollen tongue with teeth marks and white slippery coating, and a deep thin weak pulse.
Warm and tonify the spleen and kidney; transform qi and promote water movement.
Internal Accumulation of Damp-Turbidity
Dull darkish complexion, nausea and vomiting, sticky mouth with poor appetite, distension and fullness in the epigastrium and abdomen, heavy sensation of the body with lethargy, scanty or turbid urine, unsmooth stool, pale red tongue with white greasy coating, and a soft slow pulse.
Transform dampness and descend turbidity; harmonize the stomach and stop vomiting.
Blood Stasis Obstructing the Collaterals
Edema that persists over time without subsiding, darkish complexion, dry scaly skin, fixed stabbing pain in the lumbar region, hematuria or blood clots in urine, dark purple tongue with ecchymosis, and a choppy pulse.
Invigorate blood and resolve stasis; promote diuresis and reduce edema.

Daily care & prevention
Follow a low-salt, high-quality low-protein diet; avoid raw, cold, greasy foods and high-potassium items. Keep warm and prevent external contractions. Exercise moderately and avoid overexertion. Maintain emotional calm and avoid fright, which injures the kidney. Monitor daily weight, urine output, and blood pressure. Moxibustion at Guanyuan (CV4), Mingmen (GV4), and Zusanli (ST36) may warm yang and boost qi. Take herbal decoctions warm in small frequent doses. Regularly check renal function and electrolytes.
When to seek medical care
Sudden marked decrease or absence of urine, severe generalized edema, dyspnea unable to lie flat, frequent nausea and vomiting, apathy or agitation, convulsions, uremic breath, pruritus, gum or nasal bleeding, or sharply elevated blood pressure suggest turbid toxin sinking inward and water qi insulting the heart; immediate integrated Chinese-Western medical rescue is required.
