As the saying goes: water is the source of life, the normal operation of the human body is inseparable from the participation of water, maintain sufficient water, in order to enhance their metabolism, accelerate the discharge of toxins, maintain the normal operation of the body.
The water we ingest needs to form urine through the kidneys, and then garbage and toxins are mixed in the urine and finally excreted from the body, so as to reduce the burden on the body and maintain a healthy body.
However, why do some people drink a lot of water but do not go to the toilet much, while some people drink a little water and go to the toilet frequently? Are the kidneys overwhelmed? Let's listen to the doctor's answer together...
01
First of all, let's understand how the water drunk into the body is transformed into urine.
After entering the body, there will be a remnant of the body, but in the stomach the water is absorbed very little, most of the water is absorbed by the intestine, and finally enters the bloodstream, the water entering the blood will follow the blood circulation through the kidneys, and then through the kidney filtration function into the original urine.
The kidneys have two major structures, the tubules and the glomeruli, the function of the glomeruli is to filter substances, such as water, sugar, inorganic salts, urea, the function of the tubules is the reabsorption function, repeated absorption of components beneficial to the human body.
Inorganic salts, sugar, water and other substances are beneficial to the body, most of them will be reabsorbed into the human body through the reabsorption function of the renal tubules, while excess metabolic waste is excreted in the form of urine.
The speed of urine formation is related to many reasons, such as lack of water, water to drink, amount of exercise, temperature, under normal circumstances, when the kidneys are formed, urine is not excreted, but stored in the bladder, when the urine content in the bladder exceeds a certain amount, it will send a signal to the brain that I want to urinate!
The glomerular filtered primary urine is about 180 liters per day, while the daily urine output of the person is up to 1800 ml, that is, 99% of the water filtered by the glomeruli is reabsorbed into the human body.

As soon as you drink water, you will have more urine, is it that the kidneys are "overwhelmed"? The doctor finally told the big truth
After drinking water, water will be excreted in the form of urine through the conversion of the kidneys, and for people with impaired kidney function, the number of urination will also be affected, due to the decline in kidney function, the absorption and decomposition of water is abnormal, and people will have abnormal urination.
In addition, after drinking a lot of water, the amount of water entering the blood circulation will increase significantly, and the pressure felt by the kidneys will also increase, resulting in accelerated filtration function, in order to ensure the stability of electrolyte concentration, drink too much water, the secretion of antidiuretic hormone in the body will gradually decrease, this hormone mainly acts to increase the reabsorption function of the renal tubules on water, and when the antidiuretic hormone is reduced, the tubules will gradually reduce the absorption of water, so the amount of urine will increase, for healthy adults, If you drink too much water at once, the amount of urine you urinate will also increase.
If you want to know whether the kidneys are healthy, you can go to the hospital for urine routines, kidney function tests, blood counts and other examinations, and if the examination standards are within the normal range, you can conclude that the kidneys are healthy.

Abnormal urination may be related to the following points, I hope you do not take it lightly
1. Increased urine output
After drinking a lot of water, the frequency of urination will increase, which is a normal phenomenon, but there is a special situation, such as diabetes or diabetes insipidus, the number of patients urinating after drinking water increases, and the amount of urination will also increase, so when this situation occurs, it is necessary to go to the hospital for examination, so as not to affect the health of the body.
2. The bladder is small
The size of the bladder determines the amount of urine, and for people who go to the toilet as soon as they drink water, the bladder is small, so frequent urination occurs.
3, usually drink less water
If there is no habit of drinking water, the number of times to go to the toilet will gradually decrease, but suddenly change the drinking habits, drink more water, the concentration of the bladder will become abnormally sensitive, so after drinking water, it will immediately produce urinary intentions, and frequent urination will occur.
4. Usually like to hold urine
Holding urine for a long time, the bladder will become extremely sensitive to urine, and it is easy to have frequent urination problems after drinking water.
Reminder: Holding urine for a long time can easily cause toxins to accumulate in the body and cannot be excreted in time, affecting the health of the kidneys.

Read further: Whether the kidneys are good or not, 4 tests to help you identify
- Urinalysis
Through the proteinuria, hematuria, urine specific gravity and other indicators in this examination, the health of the kidneys is preliminarily judged.
- Kidney function
Mainly check the standards of serum creatinine and urea nitrogen.
Serum creatinine, in particular, is the most direct indicator of abnormal renal function.
- Urinary beta2 microglobulin
Urinary beta2 microglobulin is a sensitive indicator for determining glomerular filtration rate and tubular reabsorption function.
- Imaging of the kidneys
Imaging tests of the kidneys, including CT, ultrasound, MRI, etc., can help us clearly observe the internal conditions of the kidneys to see if there are stones, tumors, cysts and so on.
