Lao Gao called and said that his kidneys are not good recently, and asked me to prescribe some tonic tonic for him. I asked him why he thinks his kidneys are not good? He said that he has been suffering from back pain recently, and a little pain in urination. He urinated frequently but not much each time.

I told him that his condition should be more likely to be a urinary tract infection than a kidney disease, and he confuses the kidney disease of traditional Chinese medicine with the kidney disease of western medicine. For his situation, you can try to take some anti-inflammatory drugs and drink more water. It is good to control the urinary tract infection. The real symptoms of kidney disease are not like him, and once kidney disease occurs, it may be troublesome to treat.

With the advent of an aging society, the population suffering from hypertension, hyperlipidemia, hyperglycemia, and chronic diseases such as cardiovascular disease and diabetes continues to increase, thereby increasing the risk of kidney disease.

In fact, kidney disease often has no obvious symptoms at the beginning, and low back pain is generally not closely related to kidney disease. Since someone asked, in order to be able to prepare as soon as possible to prevent kidney disease. Today, I will introduce to you who are at high risk of kidney disease, and how to conduct self-examination through 7 common symptoms, which will help to detect kidney disease as soon as possible and improve the cure rate!

Who are at high risk of kidney disease?

Generally speaking, the common high-risk groups of kidney disease mainly include the following 8 types of people:

1. Obese

At present, the body mass index, or BMI for short, is used as the standard to measure obesity in the world. When BM is greater than or equal to 24, it is overweight, and it is easy to cause symptoms such as hypertension and hyperlipidemia . If it is not controlled, the risk of kidney disease in the future will increase.

2. Diabetic patients

When the fasting blood glucose is greater than 7 mmol/L or the glycosylated hemoglobin is greater than 6.5%, it can be determined as diabetes. The long-term hyperglycemia of patients may cause vascular disease, which in turn affects renal blood flow and causes nephropathy, resulting in decreased renal function. Kidney disease caused by diabetes develops rapidly and has a poor prognosis, so it is very important to control blood sugar in order to avoid dialysis in the future.

3. Gout patients

When the concentration of uric acid in the blood is too high, gout may be caused by the accumulation of uric acid crystals in the joints. Not only that, but also uric acid crystals will be deposited in the kidney tissue, which will increase the risk of kidney disease in the long run.

4. People with high blood pressure

Hypertension is defined as blood pressure greater than ¹⁴⁰⁄₉₀ mm Hg, and if not well controlled, it will cause kidney disease by sclerosis of the blood vessels and glomeruli of the kidneys.

5. Seniors over 65 years old

With the increase of age, many organs in the body will begin to gradually degenerate, including the kidneys, especially for the elderly over 65 years old, the risk of kidney function degeneration will increase significantly.

6. People with a family history of kidney disease

If close relatives of family members have kidney disease such as polycystic nephropathy and hereditary nephritis, their relatives will also be at increased risk of developing kidney disease.

7. People who smoke for a long time

Smoking stimulates the sympathetic nerves and increases blood pressure, thereby burdening the kidneys and reducing their function.

8. People who abuse drugs

Long-term use of painkillers, or taking unexplained drugs can cause damage to kidney function.

Self-testing methods for kidney disease: see the clues from 7 signs

If you want to find out whether you have kidney disease early, you can perform self-testing through 7 kinds of precursors. The following is a detailed description for you:

1. Easy to edema

If the glomeruli, which filter blood, are damaged, resulting in incomplete blood filtration and the inability to excrete excess water, salt and waste, it is easy for kidney disease patients to develop symptoms of edema in the eyelids, calves or ankles.

In addition, some people find that the wrinkles on the face disappear, or they press the calf with their hands, and the depression takes a long time to recover, so they should pay attention to whether they suffer from nephritis, kidney stones or other kidney-related diseases.

2. Abnormal urination

Generally healthy people urinate about 4 to 8 times a day, and the urine volume is about 1000 to 1500 ml. If the urine volume exceeds 2500 ml, combined with frequent urination at night, it means that there may be problems with renal function.

Of course, the amount of urination is also related to the amount of water you drink. If you drink more than 2,000 ml of water a day, it is normal to urinate more.

3. Foamy urine

Under normal circumstances, the filtration membrane of the kidney will block the loss of protein in the blood into the urine. Once the kidney function is damaged, there may be a lot of urine protein in the urine, resulting in more bubbles in the urine, and The bubbles are dense and difficult to dissolve. Generally, the bubbles exist for more than 10 minutes.

However, it is necessary to understand that the production of foamy urine does not necessarily mean that you have kidney disease. Under physiological conditions, factors such as eating too much meat, strenuous exercise, urinary tract inflammation or fever may also increase the protein in the urine. Soak urine and get checked as soon as possible.

4. Anemia

People with kidney disease are prone to anemia because the cells that make erythropoietin in the kidneys are damaged and cannot make red blood cells. At this time, the patient will appear pale, tired, and even have symptoms such as palpitations and difficulty breathing.

5. Hypertension

The kidneys secrete renin and angiotensin to regulate blood pressure. If the kidneys are damaged, the hormones that regulate blood pressure will also be out of balance, which will make blood vessels tense, increase blood vessel tension, and lead to high blood pressure. Therefore, people with high blood pressure should find out whether it is related to kidney disease.

6. Abnormal burnout

In the late stage of renal disease, due to the severe decline of renal function, the toxins and impurities contained in the blood continue to accumulate, and the patient may experience symptoms such as abnormal fatigue, inability to concentrate, nausea, vomiting, loss of appetite or insomnia.

7. Difficulty seeing close objects

Long-term elevated blood pressure in kidney disease can lead to retinopathy, which can lead to blurred vision. Therefore, if you are a high-risk group of kidney disease, and you are increasingly struggling to see close objects, you should seek medical examination as soon as possible.
