Changes in blood flow through the kidneys

When blood flows to the glomerulus, in addition to blood cells and large molecular proteins, other substances such as water, inorganic salts, glucose and urea will pass through the renal capsule to form primary urine, and then flow through the renal tubules. Most of the water and some inorganic salts and glucose are reabsorbed back into the blood. If kidney function declines, circulation in this area will deteriorate, which will have a greater impact on health.

Three signs of kidney failure

The harm of kidney disease to the human body is silent. For some people, kidney disease is quite hidden. If kidney disease can be detected early, it will help to control the condition well and prevent it from worsening. So how can we detect kidney disease in its early stages? Next, let the experts introduce three signs of kidney disease.

According to nephrologists, some daily clues can show whether you have kidney disease. The following situations should attract everyone's attention.

1. Poor gastrointestinal function and anemia . When chronic renal failure occurs, the kidneys produce less erythropoietin, which can cause anemia that is difficult to correct with any blood tonic. At the same time, after renal failure, toxins in the body cannot be effectively eliminated, which can cause uremic gastroenteritis, manifested as stomach discomfort and nausea. The mistake people often make at this time is that they only know how to check liver function and gastroscopy, but rarely remember to check kidney function. 2. The calves often produce a hormone that is secreted by the kidneys to regulate calcium and phosphorus metabolism. When kidney function declines, the decrease in this hormone can cause calcium reabsorption disorders, leading to low blood calcium, reduced bone mass, and increased risk of osteoporosis and fractures. This type of calcium deficiency caused by kidney disease is generally not effective with calcium supplementation.

3. High blood pressure can never be lowered. Since aldosterone, a substance that constricts blood vessels, is produced in the kidneys, when the kidneys are diseased, the increase in aldosterone can cause the patient to have difficult-to-control high blood pressure. This situation often occurs in patients with renal failure. The above three signs should be taken seriously by everyone. Perhaps the occurrence of these three situations is a sign of kidney problems. Once again, I would like to remind everyone that if you find that you have kidney disease, please go to a regular hospital for early detection and treatment. Don't let the condition worsen due to delay.
