Kidney supplementation is a very popular topic in recent years. Many men have unilaterally acquired some knowledge of Chinese medicine or misled by misinformation, believing that their poor energy and stamina and reduced sexual function are caused by kidney deficiency, so they blindly buy a lot of drugs or supplements for kidney aphrodisiacs to take. There are also many men who run to the hospital and say they have kidney deficiency and ask the doctor to help “make up for it”. The most important thing is that this is not only not good for your health, but also may cause harm to your body. The kidney is a comprehensive concept in Chinese medicine. Firstly, the kidney has the function of constituting the human body and maintaining its vital activities, determining the growth, development and reproduction of the human body; secondly, the kidney also plays an important regulatory role in maintaining the metabolism of water and fluid in the body; finally, the kidney also helps to cooperate with the respiratory function of the lungs, allowing smooth and deep breathing. Therefore, when a person has stunted growth, low energy and physical strength, decreased sexual function, and fertility disorders, it is time to consider if the person has kidney deficiency. However, the phenomenon of life is very complex, and these problems are also likely not caused by kidney deficiency, if you generalize and blindly supplement the kidneys, it will bring a lot of harm to men. First, disrupt the balance of yin and yang in the body. Kidney tonics either nourish Yin or Yang, and normal people will disrupt this balance and cause diseases after long-term use. There may be dry mouth, irritability, acne and other manifestations of fire, as well as loss of appetite, thick tongue, constipation and other problems. Secondly, it is easy to use the wrong medicine and aggravate the condition. Kidney deficiency can be simply divided into kidney yin deficiency and kidney yang deficiency, the clinical manifestations and pathogenesis of the two are different, so the first thing to distinguish when supplementing the kidney is kidney yin deficiency or kidney yang deficiency. If it is kidney yin deficiency but use the medicine to strengthen the kidney, it is like pouring oil on the fire; if it is kidney yang deficiency but use the medicine to nourish the kidney yin, it is like adding frost to the snow, not only can not cure the disease, but also aggravate the condition. Thirdly, it causes serious harm to the elderly. Many elderly people attribute the natural aging phenomenon to “kidney deficiency” and over-supplement the kidney and aphrodisiac. The medicine of kidney and Yang tonic is very warm and dry, so after taking it for a long time, it is easy to have a series of adverse reactions such as dry mouth, thirst, nose bleeding, red eyes, swollen and painful teeth, dry stools, insomnia and dreaminess, irritability, increased blood pressure, etc. It can even cause drug-related stroke, which can be life-threatening. If you really have uncomfortable symptoms and suspect that you have kidney deficiency, you must first consult a doctor to identify and treat the symptoms. At the same time, life should learn to properly care for the kidneys: moderate sex life; adhere to exercise; ensure adequate sleep; frequent massage of the waist, the soles of the feet.
