Pathogenesis of selected symptoms
Lack of appetite Lack of appetite originates because the Spleen function of food transformation is impaired. Sensation of fullness after meals Sensation of fullness after meals originates because the Spleen function of food transformation is impaired. Fatigue after meals Fatigue after meals originates because the Qi-production of the Spleen is impaired. Pale facial complexion Pale facial complexion originates because Qi is deficient and the transportation of Qi and Blood to the face is impaired. Weakness of the extremities Weakness of the extremities originates because the extremities are governed by the Spleen. Spleen Qi Deficiency leads to impaired transportation of Qi and Blood to the extremities. Soft stools or chronic diarrhea (with undigested food particles in the stool) Soft stools and chronic diarrhea in more severe cases, originates because the Spleen function of food transformation is impaired and Dampness accumulates. Over-thinking Over-thinking originates because the mental "digestion" is impaired. Edema Edema originates because the Spleen function of food transformation is impaired and Dampness accumulates. The Spleen is particularly susceptible to Dampness, which affects transportation and transformation. Impairment of the Spleen's function affects transportation and transformation due to other causes and may easily give rise to Dampness. The Spleen is said to be the source of Dampness. Even if Dampness manifests in other organs, the Spleen must be treated so that Dampness won't be produced again. Being excessively focused on oneself Being excessively focused on oneself may be caused by the impaired mental "digestion".
