The kidney is good, very good! Do you know your kidney?
Filter blood, regulate blood pressure... The kidneys are very. Chronic kidney disease has increasingly become one of the important causes affecting longevity, including deepening urine color, increasing nocturnal urination and skin itching. Chronic kidney disease is not obvious. 2.6 million people around the world depend on dialysis or kidney transplantation for survival. It is a serious progressive decline in renal function (marked by decreased glomerular filtration rate or kidney damage or both) and lasts for more than three months! Most patients with chronic kidney disease are often diagnosed at a later stage, and many patients are not even aware of physical discomfort until the uremic period. If there are symptoms that may be associated with kidney disease, such as eyelid or lower limb edema, foamy urine, dark urine, increased nocturnal urination, skin itching, and low back pain. When young people have high blood pressure or blood pressure is difficult to control, it is necessary to have a kidney-related physical examination for the general population every year, taking into account the fact that the performance of chronic kidney disease is often not obvious.
Chinanews.com, Beijing, March 11 / PRNewswire-Asianet /-- (Peng Ningling) the kidney plays an important role in the "purification factory" in the human body. In recent years, the incidence of chronic kidney disease has increased. Because the onset is hidden and the awareness rate is low, most patients are often diagnosed in the later stage, causing irreversible damage to the body.

Do you know your kidney?
Filter blood, regulate blood pressure... The kidney is very busy.
In recent years, the incidence of chronic kidney disease has increased. Some experts say that chronic kidney disease has increasingly become one of the important causes affecting longevity, bringing a heavy burden to families and society.
So, do you know your kidney? Do you know what role it plays in our bodies?
"the primary role of the kidney is the 'purification factory' of the human body." Chen Gang, an attending physician in the department of nephrology at Peking Union Medical College Hospital, said that the kidneys are located on both sides of the back spine and are broad bean-shaped, accounting for only about 0.5% of the body mass.
Small size and weight, but bear a lot of work. Healthy kidneys work 24 hours a day and 7 days a day without rest in the middle of the year. When blood flows through the kidneys, metabolic waste, excess salt and water in the blood will form urine and be excreted out of the body.
"in terms of quantity, the kidney can be said to be a 'strange' in the abdominal organs." Chen Gang says that intuitively, people have two kidneys because they are "very busy" and have several "part-time jobs" in addition to their own job of purifying water.
On the one hand, it regulates water and salt balance and controls human capacity to maintain normal blood pressure; on the other hand, it releases a vasoconstrictor hormone that raises blood pressure to ensure blood supply to all corners of the body, thereby regulating blood pressure.
In addition, the kidneys also assist the body in hematopoiesis and maintain the health and growth of teeth and bones.

The color of urine deepens, nocturnal urination increases, skin itches.
Chronic kidney disease performance is not obvious, these symptoms should be paid attention to!
At present, the prevalence of chronic kidney disease in adults worldwide is as high as 10%. In 2010, 2.6 million people worldwide depended on dialysis or kidney transplants for their lives; by 2030, that number is expected to rise to 5.4 million.
The so-called chronic kidney disease is a serious progressive decline of renal function (marked by decreased glomerular filtration rate or renal damage or both and lasts for more than three months).
Li Xuemei, director of the Department of Nephrology at Peking Union Medical College Hospital, pointed out that in the process of traditional diagnosis and treatment of chronic kidney disease, due to hidden onset and low awareness rate, most patients with chronic kidney disease are often diagnosed at a later stage, causing irreversible damage to the body.
"in reality, many patients are not even aware of physical discomfort until the uremic stage." Li Xuemei said that although most chronic kidney diseases are incurable, they can be prevented and delayed.
Experts believe that if there are symptoms that may be related to kidney disease, such as eyelid or lower limb edema, foamy urine, dark urine, increased nocturia, skin itching, low back pain, high blood pressure or uncontrollable blood pressure in young people, they should see a doctor as soon as possible.
In addition, considering that the performance of chronic kidney disease is often not obvious, it is necessary to conduct kidney-related physical examination on the general population every year.
"especially people with diabetes, high blood pressure, obesity or a family history of kidney disease." According to experts, positive urine occult blood is the most common abnormality in kidney-related examination.There are many reasons for positive testing.When positive urine occult blood is found, urine routine should be reviewed and urine sediment examination should be carried out to determine the number and shape of red blood cells.
In addition to the examination results of urinary occult blood, we should also pay attention to other related examination items on the physical examination report, including blood pressure, urinary protein, serum creatinine and urinary imaging results.

How to protect the kidney and prevent kidney disease?
Experts: adhere to a healthy lifestyle and monitor regularly
So, how to protect the kidney and prevent kidney disease?
"the first key to protecting your kidneys: don't make them thirsty." Chen Gang said, "hard-working kidneys are not afraid of too much work, soaking in the water is not a big deal. If they are not watered for a long time, they will wilt."
Li Xuemei further pointed out that in daily life, by adhering to a healthy lifestyle, improving metabolic abnormalities and strengthening regular monitoring can prevent and delay the occurrence of kidney disease.
Experts say healthy living requires a low-salt, low-fat diet, and adults eat no more than 6 grams of salt a day.
"for patients who already have renal function damage, salt intake should be controlled, and protein intake should be adjusted under the guidance of doctors at different stages of chronic kidney disease." In addition, don't smoke, do as much exercise as you can every week, and encourage aerobic exercise, experts say. Drinking habits are very important. It is recommended to drink boiled water or tea and drink less sugary drinks.
Second, blood sugar needs to be monitored.
"Diabetes is likely to gradually become the leading cause of chronic kidney disease in China in the future. Controlling blood sugar is an effective treatment for diabetes and kidney disease." Li Xuemei said that patients with diabetes should be closely monitored to control glycosylated hemoglobin within 7%.
According to experts, long-term uncontrolled hypertension will lead to renal arteriosclerosis, cause an increase in nocturia, and further lead to renal function damage, which in turn will aggravate hypertension and cause a vicious circle. In severe cases, malignant hypertension can occur, and the emergence of this state will aggravate renal failure. "it is necessary to control blood pressure and cut off the vicious circle between blood pressure and kidney disease."
Finally, drugs should be used with caution.
"drugs are the leading cause of interstitial glomerulonephritis. Common drugs include proton pump inhibitors, painkillers, antibiotics, and traditional Chinese medicine containing aristolochic acid, which are commonly used in the treatment of digestive tract discomfort. Avoid taking drugs or health products for a long time without the guidance of your doctor. " Experts say. (end)
