Kidney yin deficiency does not usually cause nephritis. Kidney yin deficiency is the term used in Chinese medicine, while nephritis is the term used in western medicine. Generally, kidney yin deficiency is not equal to kidney disease. Kidney yin deficiency, also known as kidney yin deficiency, kidney yin deficiency, true yin deficiency, is a symptom of kidney yin deficiency. Kidney yin deficiency is mainly manifested by symptoms such as five heart-heat (heat in the heart of both hands and feet, and self-consciousness of the heart and chest), hot flashes (a burst of heat), night sweating (abnormal sweating after going to sleep, and sweating stops after waking up), lumbar and knee pain, dizziness and tinnitus, insomnia and sleeplessness, and so on. Nephritis is not a single disease, but a group of kidney diseases caused by multiple causes of inflammatory lesions in the renal tubules and surrounding tissues, which leads to kidney injury. Its clinical types vary, but the clinical manifestations often overlap, often with edema, hypertension, hematuria, proteinuria, renal function impairment and other manifestations. In fact, kidney yin deficiency does not have a substantial disease, most of which may have more to do with the patient’s psycho-emotional factors. If kidney discomfort occurs timely consultation, please doctor to clarify the cause of the disease, give targeted treatment.
