What changes occur in blood flow through the kidneys

For healthy people, when blood flows to the kidneys, the glomeruli and renal tubules come into play. The blood cannot be filtered, and other small molecules are stuffed into the renal capsule and then pass through the renal tubules, while some other nutrients are reabsorbed, and some waste and water are excreted from the body through the kidneys. If the kidney function is diseased, there will be problems with the blood and some toxins cannot be metabolized.

Symptoms of kidney failure:

1. Boring

When the kidney function is poor, many wastes are difficult to excrete from the urine, resulting in feelings of lack of energy, fatigue, weakness, and other signs of lethargy.

If the kidneys are diseased, nutrients such as protein will leak out of the kidneys and be excreted from the body through urine, which may also cause weakness. Some patients ignore kidney problems, thinking they are due to overwork or other reasons.

2 Don't want to eat

Loss of appetite, anorexia, or even nausea and vomiting are also common symptoms of kidney disease. Some patients always go to the gastroenterology or hepatology department first to see if they have stomach or liver disease. But when they find out they don’t have stomach or liver disease, they just leave it alone and forget to see a nephrologist, which delays their treatment.

3. Foamy urine

There are many reasons why there is foam in the urine. If protein leaks from the kidneys into the urine, the urine will be foamy.

4. Low back pain

The kidneys are located on both sides of the spine in the waist, so when the kidneys are diseased, you will feel back pain.

5. Frequent or infrequent urination

A healthy person urinates about 4-6 times a day, with a urine volume of about 800-2000 ml. If the frequency of urination and urine volume are too much or too little, you should pay attention.

6 Edema

Drinking too much water, sleeping too long, being too obese, etc. may cause slight edema or transient edema in the eyelids, face, calves, etc. If this is not the case, you should suspect that there is a problem with your kidneys.

7 Urine protein and occult blood

The presence of protein or occult blood in the urine is an important indicator of kidney disease, which can be confirmed by a routine urine test. But sometimes doctors who are not specialized in nephrology may overlook this point. It is recommended that you consult a nephrology specialist.

8 Anemia

Patients with anemia often go to the hematology department to see a doctor for anemia. In fact, in addition to excreting waste and other functions, the kidneys also have endocrine functions and secrete hematopoietic hormones. When kidney function is impaired, anemia can also occur.

9. Diabetes

Diabetes can cause kidney disease, which is called diabetic nephropathy, and is a complication of diabetes. Diabetic nephropathy is divided into five stages. The treatment effect is better in the early stages. Once it is late, it will be difficult to treat and will develop into uremia. Therefore, diabetic patients must always see a nephrologist.

10. Hypertension

Hypertension can cause hypertensive nephropathy, also known as hypertensive renal damage, so people with hypertension should pay more attention. Of course, kidney disease can also cause high blood pressure. If your blood pressure is high, you should be careful about whether you have kidney disease.
