Spleen and Kidney Qi Deficiency

Understanding Spleen and Kidney Qi Deficiency

The Spleen is the source of Qi produced from food, and the Kidney holds the body's constitutional Qi. When both are weak, production and reserve are low at the same time, so the fatigue is deeper than in Spleen deficiency alone.

Appetite is poor and stools are loose or watery, while the lower back and knees ache with a weak feeling. Urine is frequent, sometimes at night.

Fatigue is the leading complaint: it is deep, constant and worse with any effort. The tongue is pale, swollen and teeth-marked with a white moist coat, and the pulse is weak, especially at the Spleen and Kidney positions.

It follows chronic illness, ageing, poor diet or overwork, and it often begins as Spleen deficiency that gradually involves the Kidney.

Treatment tonifies both. Warming and drying must be balanced, because the Spleen needs dryness but the Kidney needs moisture, and the two are treated together with gentle support.

Signs and symptoms

Key signs

• Chronic fatigue and lack of physical strength
• Poor appetite with loose or watery stools
• Soreness and weakness of the lower back and knees
• Frequent or excessive urination

Also seen

• Puffiness in the face
• Cold limbs
• Shortness of breath on exertion
• Undigested food in the stool
• Dizziness on standing
• Low motivation

Variations

• Nocturia
• A bearing-down feeling in the abdomen
• A weak voice

Timing

• Fatigue is worse in the morning and after exertion.
• Urinary frequency is worse at night.

Practitioner notes

• The tongue is pale and swollen with teeth marks and a white moist or slippery coating.
• The pulse is weak, particularly at the right guan and both chi positions.
• The distinction from Spleen Qi deficiency alone is the lower back, knee and urinary involvement.
• The distinction from Kidney Yang deficiency is the absence of marked coldness; here it is Qi rather than Yang that is primarily low.

Causes

Common causes

• Chronic illness wearing down both organs
• Ageing and natural decline
• Poor diet over a long period
• Overwork, physical labour or mental exhaustion

How it develops

• It develops slowly from long-standing deficiency in one organ spreading to the other.
• If it deepens, Yang deficiency with coldness or fluid accumulation can follow.

Diagnosis

Diagnosis rests on digestive weakness together with lower back and urinary signs, with a weak pulse.

Tongue

• Body: Pale and swollen with teeth marks.
• Coating: White and moist or slippery.
• Note: A yellow coat would suggest Heat.

Pulse

Weak, Deep, Slow

Weak at the Spleen and Kidney positions.

Observation

• Pale, slightly puffy face
• A tired bearing
• Weak limbs

Listening

• A weak voice
• Reports of frequent urination

Palpation

• Abdomen: Soft and weak; the lower abdomen may feel cool.
• Channels: BL-20 and BL-23 may feel empty and tender.

Questions that separate it from look-alikes

• How is the appetite and the stool?
• How frequent is urination, including at night?
• How is the lower back?
• How much overwork and what is the diet?

Treatment

Principles

• Tonify Spleen Qi
• Tonify Kidney Qi and secure the lower body
• Support digestion so the tonics are absorbed
• Avoid over-drying and over-rich tonics

Herbs

Formulas

• Si Jun Zi Tang - The foundational Spleen Qi tonic, the base for this pattern.
• Shen Ling Bai Zhu San - For Spleen deficiency with Dampness and loose stools.
• Shi Shen Tang - For Spleen and Kidney deficiency with chronic diarrhoea.
• Wu Zi Yan Zong Wan - For Kidney deficiency with frequency and weakness, astringing and warming.
• Bu Zhong Yi Qi Tang - For Qi deficiency with sinking and fatigue.
• Jin Gui Shen Qi Wan - For the Kidney deficiency component, used where Yang is also low.

Acupoints

• Zusanli ST-36 - Builds Qi from digestion.
• Shenshu BL-23 - The Kidney back-shu point, used for lower back weakness and urinary signs.
• Zhongwan REN-12 - Strengthens the Stomach and Spleen.
• Taixi KI-3 - The Kidney source point, used for weakness and urinary symptoms.
• Sanyinjiao SP-6 - Supports the Spleen and regulates the lower body.

Personalising the plan

• If diarrhoea dominates, astringing and warming herbs are increased.
• If urinary frequency dominates, herbs that secure the lower body are increased.
• If coldness is present, gentle warming is added.
• If the digestion is very weak, the tonics are introduced gradually.

Self-care

Diet

• Warm cooked food; small frequent meals
• Avoid cold, raw and iced food
• Adequate protein
• Reduce dairy and greasy food

Lifestyle

• Pace activity and rest before exhaustion
• Regular meals
• Keep the lower back warm
• Adequate sleep

Qigong and movement

• Slow practice building strength gradually, focusing on the lower abdomen.

How it differs from look-alikes

Patterns that can be mistaken for spleen and kidney qi deficiency, and the contrast that separates them.

Where it appears

Skin conditions in which this pattern is commonly seen.

Safety and when to get help

For anything severe, sudden or spreading quickly, read when a skin problem needs urgent care.

This page describes a TCM pattern, not a diagnosis, and a pattern can accompany more than one skin condition. Get urgent medical help for a rash with fever, confusion or feeling very unwell; skin that is blistering, peeling or spreading quickly; swelling of the face, lips or throat, or difficulty breathing; or a lesion with increasing pain, warmth, red streaks or pus. For anything persistent, severe or changing, have it assessed by a clinician before treating it yourself.

Read the skin condition pages for the red flags that belong to a specific presentation.

Urgent-sign guidance is based on standard sources: NHS anaphylaxis, NHS cellulitis, NHS Stevens-Johnson syndrome, NHS melanoma.

Evidence note

No controlled trial of this treatment in skin conditions was identified for this entry. What is described here rests on the classical and later materia medica record and on traditional clinical use, not on controlled trial evidence, and it is not a prediction of benefit. Where skin-specific research does exist it is linked above.
