Nephrotic syndrome is a kidney disorder characterized by a set of symptoms including proteinuria (excessive protein in the urine), low blood protein levels, high cholesterol levels, and swelling (edema).
This condition results from damage to the blood-filtering units of the kidneys (glomeruli) and can arise from various causes, ranging from genetic disorders to immune system dysfunctions. Managing nephrotic syndrome often involves treating the underlying cause, if known, and addressing its symptoms to prevent complications such as kidney failure.
In Traditional Chinese Medicine (TCM), nephrotic syndrome is viewed as a complex result of internal disharmonies rather than simply a kidney ailment. TCM practitioners focus on identifying and correcting imbalances in the body's vital energy (Qi), along with Yin and Yang disruptions.
They believe that such imbalances, particularly in the kidney and spleen systems, contribute to the characteristic symptoms of nephrotic syndrome. This holistic approach emphasizes treating the underlying causes to restore overall bodily harmony and health.
TCM Patterns for Nephrotic Syndrome
Each pattern represents a distinct underlying imbalance that can cause nephrotic syndrome
Spleen Deficiency with Dampness
Diagnostic signs
Soggy (Ru), Slowed-down (Huan), Slippery (Hua), Deep (Chen)
The tongue is characteristically pale and swollen, often appearing puffy and tender, with clear teeth marks indented along both edges. The coating is white and greasy (or thick and greasy in more pronounced cases), reflecting the accumulation of Dampness in the Middle Burner. The tongue surface is typically moist or even excessively wet. In some cases, the coating may be slightly slippery. If the Dampness is particularly heavy, the coating may appear thick and white across the entire tongue body, sometimes most prominent in the centre (corresponding to the Spleen and Stomach area).
Phlegm in the Lower Burner
Diagnostic signs
Slippery (Hua), Deep (Chen), Slow (Chi), Wiry (Xian)
The tongue is characteristically pale and swollen, often with teeth marks along the edges from pressing against the teeth, indicating fluid accumulation. The coating is notably thick, white, and greasy, particularly at the root (back portion) of the tongue, which corresponds to the Lower Burner. The entire tongue surface tends to appear wet or slippery. In some cases the coating may extend thicker toward the centre and rear while being thinner at the front, reflecting that the pathological material is concentrated in the lower and middle parts of the body.
Phlegm
Diagnostic signs
Slippery (Hua), Wiry (Xian)
The classic Phlegm tongue is swollen and pale with tooth marks along the edges, reflecting the Spleen's inability to properly manage fluids. The coating is the most diagnostic feature: it is characteristically white, thick, and greasy or sticky, indicating the presence of turbid Phlegm and Dampness. The tongue body is typically moist to wet. If Phlegm begins to transform with Heat, the coating may turn yellowish and greasy, but in the base pattern the coating remains white. The tongue body itself is not red or purple, distinguishing this from Phlegm-Heat or Phlegm with Blood Stasis transformations.
Yang Deficiency with Cold-Damp
Diagnostic signs
Deep (Chen), Slow (Chi), Minute (Wei), Soggy (Ru)
The tongue is characteristically pale and swollen, often with teeth marks along the edges where it presses against the teeth due to its enlarged size. The coating is white, moist, and often greasy or slippery, reflecting the accumulation of cold dampness internally. In milder presentations, the coating may simply be thin and white. The tongue body itself feels soft and flabby rather than firm. The excessive moisture on the tongue surface directly reflects the body's inability to transform and transport fluids properly due to Yang deficiency.
Kidney Yang Deficiency
Diagnostic signs
Deep (Chen), Slow (Chi), Weak (Ruo)
The tongue in Kidney Yang Deficiency is characteristically pale and puffy, often with a soft, tender quality and visible indentations from the teeth along its edges. The surface tends to be wet or slippery, reflecting the body's inability to properly transform and move fluids. The coating is white and may appear moist or slippery. In more severe cases, the tongue can become quite swollen and waterlogged in appearance. The root of the tongue (corresponding to the Kidney area) may appear particularly pale or enlarged.
