4 kinds of manifestations in the body, or the 'call for help' issued by the kidneys, need to be vigilant

The overall kidney is generally divided into two left and right, but there will also be a small part of one kidney. The kidneys have the function of expelling toxins from the body, expelling excess water and part of the endocrine function.

The kidneys secrete erythropoietin, promote hematopoiesis, and regulate calcium and phosphorus disorders. If the kidneys are not functioning properly, the accumulation of edema and toxins will occur, resulting in anemia, low calcium, high phosphorus and other abnormal manifestations.

Under normal circumstances, a person's two kidneys cannot give full play to their maximum effect under normal circumstances, but if the kidneys are lacking, the kidneys will open up the reserve function that the kidneys cannot use because they need to ensure the stability of the body.

In recent years, people's diet structure has changed greatly, so that the number of kidney diseases has increased year by year. It is estimated that 850 million people in the world suffer from kidney disease due to various reasons. Among them, chronic kidney disease has a low awareness rate, high morbidity and high mortality, and is known as the "silent killer".

【Urine changes】

The early signs of kidney failure are mainly manifested in changes in urine properties, such as blood in the urine, increased foam during urination, increased nocturia, decreased urine output, frequent urination, urgency, dysuria and other urinary tract irritation symptoms. If a layer of foam floats on the surface of the urine for a period of time, it may be an early sign of nephritis, or suggest that the patient's prostate is inflamed.

【Puffy body】

The kidney is the organ that metabolizes water in the human body. If the kidney is not good, water will accumulate. Some people have swollen eyelids or swollen feet and legs after getting up in the morning.

【High blood pressure】

Elevated blood pressure due to renal parenchymal lesions and renal artery lesions, which is a kind of nephrotic hypertension, is a kind of secondary hypertension, mainly due to glomerular hyalinization, interstitial tissue and connective tissue hyperplasia, renal Tubular atrophy and narrowing of renal arterioles cause both substantial damage to the kidneys and insufficient blood supply.

【Increase in serum creatinine】

Creatinine is mainly excreted through the kidneys. In the early stage, when the kidneys can still compensate, the serum creatinine will not increase. Only when the renal function is decompensated, the creatinine level in the blood will increase. Therefore, once the serum creatinine increases, it is often It shows that renal function has been damaged to a certain extent.

Compared with the previous three signals, the increase in serum creatinine is a relatively late signal. If you don’t pay attention, the next step may be uremia.
