ABNORMAL METABOLISM OF BODY FLUIDS
The formation, distribution and excretion of Body Fluids is a complicated process requiring the coordination of many Organs. Thus, pathological changes in any of the Organs may affect the normal metabolism of Body Fluids, especially those of the Lungs, Spleen and Kidneys, since they are the key Organs involved in the metabolism of water.
Any disturbances in the transportation, distribution and excretion of Body Fluids may cause the stagnation of water. This manifests as Phlegm retention diseases and edema. On the other hand, pathological changes of Body Fluids also affect the functions of the Organs. For example, insufficient Body Fluids in the Lungs causes dry cough, while excessive Body Fluids in the Lungs can cause congestion with difficult breathing and cough.
An excess of Body Fluids is called 'Dampness'. The most common characteristic is a feeling of heaviness of the body or head. Fluid (or Damp) diseases include edema, Phlegm retention diseases, lymphatic problems and general fluid and cellular metabolism issues which, when not properly functioning, can also give rise to tumors, cysts and cancers.
A lack of fluids is also considered a Body Fluid imbalance (Deficiency), since the body requires a certain amount of lubrication for normal function of the respiratory, alimentary and reproductive systems. Body Fluid is necessary for proper joint lubrication as well as a moistener for the intestines to promote proper bowel function.
Phlegm, the other type of Body Fluid imbalance, can collect in the joints, skin, channels or Organs causing diverse imbalances. It forms when the Spleen, Lungs or Kidneys are unable to perform their transforming, transporting or excreting functions properly. The congested Body Fluids then transform into Phlegm, causing further bodily dysfunction.
Body Fluids imbalances can be divided into three categories: a Deficiency of Body Fluids, edema, and Phlegm blockage. Body Fluid Deficiency usually relates to a Deficiency of Yin or Blood, while edema or Phlegm always involve the Spleen, as its Qi is in charge of transforming and transporting Body Fluids.
