Swelling & Water Retention

Also called:EdemaSwellingFluid retentionPuffy swelling

From the TCM perspective: TCM 'shui zhong' (yang/yin water); located in lung, spleen and kidney, involving bladder and triple burner.

Overview

Edema is fluid retention spreading into the tissues, causing puffiness of the face, eyelids, limbs or whole body. The Suwen links water swelling to lung, spleen and kidney. Patterns include external wind-water obstruction, spleen deficiency with damp encumbrance, kidney yang deficiency and qi stagnation with fluid accumulation; swelling above the waist is often attributed to lung, below to spleen-kidney.

☯Common patterns (syndrome differentiation)

Wind-water obstruction (yang water)

Key distinguishing signs: Sudden eyelid swelling spreading to limbs and whole body, with fever/aversion to cold, heavy aching joints and cough, thin white coat, floating tight or floating rapid pulse.
Treatment principle: Dispel wind, diffuse the lung and move water

Spleen deficiency with damp encumbrance (yin water)

Key distinguishing signs: Pitting lower-limb edema that recovers slowly, poor appetite, bloating, heavy body, loose stool, sallow face, fatigue, pale tongue with white greasy coat, soggy slow pulse.
Treatment principle: Strengthen spleen qi and drain dampness

Kidney yang decline (yin water)

Key distinguishing signs: Generalized edema worse below the waist, cold sore heavy back, cold limbs, scant urine, dark dull face, pale enlarged tongue, deep fine pulse.
Treatment principle: Warm kidney yang and transform qi to move water

Qi stagnation with fluid accumulation

Key distinguishing signs: Edema fluctuating with mood and menstruation, abdominal/rib distending pain, belching, scant urine, thin coat, wiry pulse.
Treatment principle: Soothe liver, move qi and drain water

Daily self-care

Record weight, morning/evening changes and urine output; move regularly, elevate the legs and avoid prolonged sitting/standing.
Limit salt as advised; do not self-use diuretics long term or severely restrict water.
New or progressive edema warrants evaluation of heart, kidney, liver, thyroid and leg veins.

When to seek medical help

The following warning signs require prompt medical evaluation — do not rely on self-treatment:

Sudden breathlessness, blue lips or pink frothy sputum: emergency (acute heart failure/pulmonary edema).
One calf markedly swollen, painful and warm: promptly rule out DVT.
In pregnancy, edema with headache, blurred vision, high blood pressure or reduced urine: urgent care (preeclampsia).
