How to know kidney yang deficiency or kidney yin deficiency

In traditional Chinese medicine, kidney deficiency is divided into two categories: kidney yin deficiency and kidney yang deficiency. If the current patient shows kidney deficiency, first of all, the nature of kidney deficiency should be clarified. If it is mainly kidney yin deficiency, then the patient may clinically show some hot flashes, night sweats, yellow urine, thirst and excessive drinking. If the current patient mainly has some kidney yang deficiency, then clinically it may be manifested as cold limbs, fear of cold, mental fatigue, pale complexion, or even incomplete stool. If it is mainly kidney yang deficiency, then you need to take some Chinese medicine for tonifying kidney and yang. If it is mainly yin deficiency, then you need to take some drugs for nourishing yin and kidney. At the same time, it should be noted that some patients are accompanied by symptoms of yin deficiency and yang deficiency. This kind of treatment requires systematic use of drugs for nourishing yin and kidney and warming kidney and yang.
