Spleen deficiency in infants may be characterized by loss of appetite, tiredness, swollen limbs, and yellowish color (yellowish and lack of luster). Spleen deficiency refers to the weakness and diminished function of the spleen, which can be clinically categorized into spleen qi deficiency, spleen yang deficiency and spleen blood deficiency. When an infant’s spleen is deficient, the function of transportation and digestion is dysfunctional, resulting in loss of appetite and abdominal distension. The water and grain essence cannot nourish the body, thus manifesting as mental lethargy and yellowish color (yellowish and lusterless face). The metabolism of water and liquid is imbalanced and stagnant in the body, resulting in swollen limbs. When infants have the above symptoms, it is a spleen deficiency syndrome and they should go to the hospital for timely consultation and treatment. And in daily life, pay attention to feeding, not too full, so as not to cause indigestion.
