Spleen and kidney yang deficiency

　　Long-standing illness in the spleen and kidney consumes qi and injures Yang, leading to kidney Yang deficiency, unable to warm the spleen Yang, or long-term deficiency of spleen Yang, unable to nourish kidney Yang, eventually leading to both spleen and kidney Yang deficiency.

　　The etiology of spleen and kidney Yang deficiency is relatively complex, such as weakness due to old age, internal injury due to fatigue, or long-term illness without relief, which can all cause this syndrome. According to the different changes in the development of the disease, there are differences between spleen affecting kidney and kidney affecting spleen. Those affected by spleen to kidney are mostly due to weakness of the spleen and stomach, or injury from diet, or injury to the spleen due to worry and thought, or cold and dampness affecting the spleen, or due to prolonged diarrhea, dysentery, edema, and other diseases that do not heal for a long time, leading to spleen Yang deficiency.

　　Spleen deficiency leads to insufficient transformation and transportation, unable to produce essence to nourish the kidney, or internal retention of dampness, affecting the kidney Yang's function of transforming body fluids, leading to kidney Yang deficiency over time, eventually forming a syndrome of spleen and kidney Yang deficiency. As for those caused by kidney affecting spleen, it may be due to insufficient congenital endowment, inherent kidney Yang deficiency, or improper postnatal nourishment, kidney injury due to sexual overexertion, or long-term illness consuming kidney Yang, leading to kidney Yang deficiency first, then spleen Yang loses warmth; or kidney water泛滥, causing spleen Yang injury. Over time, it forms a syndrome of spleen and kidney Yang deficiency. In summary, whether it is spleen Yang deficiency or kidney Yang deficiency, under certain conditions, they can develop into a syndrome of spleen and kidney Yang deficiency.

　　In traditional Chinese medicine, spleen and kidney Yang deficiency refers to the deficiency of spleen and kidney Yang, with the loss of warming power, manifested as a cold deficiency syndrome with diarrhea or edema as the main symptoms. This syndrome is often caused by chronic illness of the spleen and kidney, consuming Qi and Yang, or prolonged diarrhea and dysentery, or long-term retention of water evil, leading to kidney Yang deficiency, unable to warm the spleen Yang, or spleen Yang deficiency for a long time, unable to nourish kidney Yang, eventually causing both spleen and kidney Yang to be injured, with symptoms such as diarrhea, swelling, cold pain in the lower back and abdomen, and accompanied by signs of deficiency and cold as the basis for diagnosis.

　　The kidney is the root of congenital energy, and kidney Yang is the foundation of the Yang energy in the body. The spleen relies on the warming of kidney Yang to normally transform and transport the essence of grains and cereals and dampness.

　　The spleen is the root of postnatal energy, transforming and transporting the essence of grains and cereals to nourish the whole body. Although the essence stored in the kidney is inherited from the congenital, it must be continuously nourished by the postnatal.

　　The kidney governs body fluids and must coordinate with the spleen's function of transforming and transporting dampness to maintain the balance of body fluid metabolism.

　　Therefore, the spleen and kidney depend on each other to ensure the normal functioning of the transformation of essence and fluid and water metabolism.

　　Long-standing illness in the spleen and kidney consumes qi and injures Yang, leading to kidney Yang deficiency, unable to warm the spleen Yang, or long-term deficiency of spleen Yang, unable to nourish kidney Yang, eventually leading to both spleen and kidney Yang deficiency.

　　Yang deficiency in the spleen and kidney is often caused by severe cold invasion, or prolonged illness consuming qi and damaging the Yang of the spleen and kidney, or prolonged diarrhea damaging the Yang of the spleen and kidney, or deficiency of other organs affecting both the spleen and kidney. Yang deficiency in the spleen leads to dysfunction of the large intestine, manifested as diarrhea or constipation. Malabsorption syndrome, ulcerative colitis, and habitual constipation often occur or are accompanied by this symptom. The symptoms of Yang deficiency in the spleen and kidney include the following three aspects:

　　1. Yang deficiency with severe cold, qi stagnation, manifested as pale complexion, aversion to cold, cold limbs, soreness in the waist and knees, and cold pain in the abdomen.

The tongue is pale and swollen with tooth marks, the coating is white and slippery, and the pulse is deep, slow, thin, and weak, which also indicates Yang deficiency.
