World Kidney Day

World Kidney Day, jointly proposed by the International Society of Nephrology and the International Kidney Foundation, is celebrated on the second Thursday of March each year.

The 17th World Kidney Day will be held on March 11, 2022.

1 in 10 people in the country have kidney disease

According to the American Society of Nephrology (ASN), the European Society of Nephrology-European Dialysis and Transplantation (ERA-EDAT) and the International Society of Nephrology (ISN), there are currently at least 850 million people worldwide with kidney disease!

According to a data published by Lancet, the number of people with chronic kidney disease in China is 130million, which means that there is one chronic kidney disease patient in every 10 people in the country on average, and chronic kidney disease has gradually left the impression of the so-called "old people's disease" in recent years, and the trend of rejuvenation is becoming more and more obvious.

Understanding the kidneys

The kidneys are paired lentil-shaped organs, reddish-brown in color, located in the shallow fossa on either side of the retroperitoneal spine.

Its basic function is to produce urine to remove metabolites and certain wastes and poisons from the body, and to retain water and other useful substances such as glucose, protein, amino acids, sodium ions, potassium ions, sodium bicarbonate, etc. Through reabsorption to regulate water and electrolyte balance and maintain acid-base balance.

The kidney also has endocrine functions, producing renin, erythropoietin, active vitamin D3, prostaglandins, kinins, etc. It is also the degradation site of some endocrine hormones and the target organ of extra-renal hormones in the body. These functions of the kidney ensure the stability of the body's internal environment and enable normal metabolism.

Understanding Chronic Kidney Disease

According to the Guidelines for the Screening Diagnosis and Prevention of Chronic Kidney Disease, chronic kidney disease is defined as a kidney with structural or functional abnormalities & gt; 3 months; the presence of any of the indicators of kidney injury (proteinuria, abnormal urinary sediment, tubular-related lesions, histological abnormalities, structural abnormalities seen on imaging, history of kidney transplantation) and decreased glomerular filtration rate for more than 3 months is diagnosed as chronic kidney disease.

Who is prone to chronic kidney disease

The three most common kidney diseases in China are diabetic nephropathy, chronic glomerulonephritis and hypertensive nephropathy, so the following people should be vigilant!

10 categories of high-risk groups

1, diabetic patients.

2. Chronic infections with recurrent respiratory, urinary tract and intestinal infections that predispose to glomerulonephritis.

3. Patients with hypertension.

4, patients with hyperuricemia.

5, long-term use of nephrotoxic drugs such as painkillers, antimicrobials and Chinese medicine.

6, elderly people over 65 years of age.

7. Those with a family history of chronic kidney disease

8, patients with autoimmune diseases such as systemic lupus erythematosus, systemic small vessel vasculitis, rheumatoid arthritis, etc.

9. Those with recurrent purpura.

10, elderly people with prostate enlargement or habit of holding urine.

Kidney health from urine color

Did you know? Urine is the "code" that reflects the health of the kidneys! Abnormal urine color or texture may be a manifestation of disease, which needs to be investigated by specialists as soon as possible.

Doctors from the Department of Nephrology of Chengdu Third People's Hospital will teach you how to identify the meaning of different colors of urine. It is also reminded that it is necessary to include urine examination into physical examination to help early detection, early diagnosis and early treatment of kidney diseases. And early through standardized treatment, many kidney diseases can achieve better treatment results.

What bad habits "hurt kidney"?

According to the national hemodialysis patient registry, the proportion of patients in the age group of 20 to 44 has been increasing significantly in recent years.

Therefore, young people should not let down their guard! Especially the busy white-collar workers, because many of their work habits are very "kidney damage".

First, long-term work on the computer, lack of exercise, sedentary.

The second is to work overtime and stay up late, and like to order take-out when working overtime, eat and drink, or smoking to refresh when working overtime, these will make the kidneys work for a long time, without rest, thus increasing the burden on the kidneys, resulting in kidney damage.

Suggestions]

First of all, do not often hold urine, because when holding urine bacteria are easy to reproduce, easy to cause urinary tract infections.

Second, you need to quit smoking, long-term smoking will increase the risk of hypertension, which can lead to kidney disease. In addition, pay attention not to over-exercise, inappropriate exercise will induce rhabdomyolysis, and even lead to acute kidney failure.

"Kidney" health tips

1, do not often hold urine

2, do not smoke and drink

3, do not over-exercise

4, do not overeat

5 、 Don't stay up late

6 、 Don't abuse drugs

Screening of kidney disease

1 、 Routine kidney examination including urine routine, kidney function, urinary system ultrasound, etc.

2, slightly more complex items also include urine microalbumin/creatinine, urine protein quantification, urine phase contrast microscopy, estimation of glomerular filtration rate and other tests.

3 、 Specialized tests include renal penetration kidney histopathology, renal function imaging, genetic testing, etc.

At present, the international advocacy of early screening of chronic kidney disease "three steps".

Firstly, blood pressure should be measured, as hypertension is an important cause of chronic kidney disease and also the main clinical manifestation of chronic kidney disease.

Secondly, routine urine examination to detect urine protein.

Thirdly, kidney function should be checked.

Under what circumstances do we need to screen kidney function?

1, patients over 35 years of age for the first visit to measure blood pressure, and for hypertension that occurs before the age of 40, be sure to perform urine routine, renal function, and ultrasound of both kidneys.

2, routine urine as a routine medical examination. Those with abnormal urine tests should undergo complex or even specialized kidney examinations.

3 、 Patients with hypertension, diabetes mellitus and hyperuricemia of more than 5 years must undergo urine routine, urine microalbumin/creatinine, kidney function, double kidney ultrasound and other examinations.

4. Routine kidney examination for those over 65 years of age.

5, those with recurrent respiratory infections and recurrent purpura should undergo routine renal examination.

6, long-term use of non-steroidal anti-inflammatory drugs (antipyretic and analgesic drugs), Chinese medicine to carry out routine kidney examination.

7 、 People with family history of kidney disease should have regular routine kidney examination.

Kidney-friendly foods

Cabbage

Cabbage is rich in vitamin C, vitamin E, carotene, etc. The total vitamin content is three times more than that of tomatoes. The various phytochemicals in cabbage help to scavenge free radicals in the body, and kidney disease patients receiving dialysis would do well to eat more cold cabbage.

Fish

Fish (especially deep-sea fish) is rich in omega-3 fatty acids that fight inflammation and help protect the kidneys. Fish is also a great source of high-quality protein.

Fruit juices

Fruit or vegetable juices are effective in breaking down and removing waste from the body. Fruit and vegetable juices contain a variety of phytochemicals that help prevent the risk of kidney failure in dialysis patients, especially berry juices such as blueberry, which are rich in antioxidants and help improve kidney health.

Red pepper

Capsaicin, the key ingredient in red chili peppers, helps break down waste in the body (especially the blood). Therefore, red peppers are the perfect food for healthy kidneys.

Egg whites

Protecting your kidneys requires a low-protein, low-phosphorus diet, but you also need to get enough protein. Egg whites contain a variety of healthy proteins and are lower in phosphorus than other sources of protein.

Broccoli

In addition to being rich in many essential nutrients such as vitamins, minerals, chlorophyll and beta-carotene, broccoli is also rich in beneficial ingredients such as indoles and thiocyanates, which help to remove toxins from the body and thus reduce the burden on the kidneys. The easiest way to eat broccoli is to boil it in water and add pepper and salt.
