The number of patients coming to the clinic to see kidney disease is getting younger and younger. When these young people are first diagnosed with kidney disease, most of them can't think, they think they are young, how come they have kidney disease? To know the answer to this question, it is necessary toUnderstand what the kidneys are mainly for and what functions they have. If you know this, you will naturally understand. Then the following is to talk about this topic.

The kidney is an important organ of the human body, which we in Chinese medicine regard as the "innate essence". It has a variety of important functions such as excreting metabolites and regulating water, electrolytes and acid-base balance, maintaining the stability of the internal environment of the body.

When blood flows through the glomerulus, large components, such as red blood cells, white blood cells, platelets, proteins, etc., cannot pass through the net, so they cannot be filtered out from the glomerulus and remain in the blood vessels; while small components, such as water, sodium, nitrogen, urea, sugar, etc., can pass through the net, filter out through the glomerulus and flow into the renal tubules, which is called "primary urine". This fluid is called "primary urine". When primary urine flows through the renal tubules, the tubules have the function of reabsorption, so 99% of the water will be absorbed back into the body, and almost all of the nutrients will be reabsorbed back into the body, at this time only the metabolic waste of the body and very little water is left, and urine is formed. The kidneys regulate the amount of urine, when it is hot, sweating more, or when drinking less water, the amount of urine will be less; and when drinking more water, the amount of urine will be more, that is, how much we eat and drink, how much the normal kidneys can work to maintain the balance of water in the body.

In the process of metabolism, the human body produces many wastes, and the kidneys are equivalent to the sewage treatment plant of the human body, many wastes are excreted by the kidneys through urine to maintain normal physiological activities. Creatinine, urea nitrogen and creatine are the main chlorine-containing metabolites, which are filtered out from the glomerulus.

Creatinine is usually not reabsorbed by the renal tubules, while urea is partially reabsorbed. When kidney failure occurs, metabolites accumulate in the body and the body becomes a "big dump". The internal environment must be stable in order for cells and tissues to metabolize normally and for organs to function properly. The so-called stable internal environment mainly refers to the electrolyte concentration, pH and osmotic pressure in body fluids, including plasma, intercellular fluids and other extracellular fluids, within the normal range. The kidneys play an important role in maintaining a stable internal environment by retaining sodium, potassium, chloride and bicarbonate and excreting hydrogen ions to maintain acid-base balance and electrolyte balance, and by excreting water to regulate the amount of extracellular fluid and osmotic pressure. When the kidney has problems and renal dysfunction, it can cause acidosis, edema, and electrolyte disorders.

The kidney also has an important role in endocrine. The kidney can secrete certain hormones, such as erythropoietin, renin, prostaglandin, and active vitamin D, which affect the metabolism and function of the whole body or the kidney itself.


Also, the kidney is the inactivation site of certain endocrine hormones, such as insulin and gastrin. In addition, the kidney is also the site of action of certain endocrine hormones, such as antidiuretic hormone, parathyroid hormone, calcitonin, glucagon, etc. When the kidney fails, the production and inactivation process of these hormones cannot be carried out normally, which can cause severe anemia, elevated blood pressure and disorders of calcium metabolism.

In conclusion, kidneys have many important functions, which are essential for maintaining human health, and because of this, when kidney diseases occur, many symptoms can appear and cause harm to human body in many ways.
