The kidney is an important organ of the human body, and it is also the first organ in the urinary system to produce urine. Therefore, many friends will associate kidney health with the number of urination. If a person urinates more than others, he is often called "kidney is not good". In fact, compared with kidney health problems, there are many reasons for the increase in urination times.
a
Before talking about the reasons for the increase in urination times, let's talk about the normal urination times of normal people and normal healthy people. Generally speaking, it is normal for normal people to urinate 4-8 times a day, and the frequency of urination at night is generally 0- 1 time. Old people may get up a little more, but they usually don't get up more than twice. If we drink water normally and urinate a lot, it deserves our attention. The following reasons deserve our attention.
1, foam urine
It is normal for healthy people to be impacted by water flow when urinating, and a small amount of foam will be produced on the surface of urine, but it will soon disappear.
However, if fine foam appears on the surface after urinating, just like beer foam, and it does not disappear for more than 20 minutes, it may be a signal of kidney disease.
Due to the decrease of glomerular filtration function, macromolecular substances penetrate into urine, which leads to the increase of urine indicating tension, thus inducing vesicular urine, which is also called "proteinuria" clinically.

2. The problem of physiological polyuria
Due to the increase of urine volume or the influence of external environmental factors, the frequency of urination increases, which usually belongs to physiological polyuria. This situation is generally not caused by health problems, but will disappear with the elimination of influencing factors, so don't worry too much.
For example, drinking too much water will lead to an increase in urine volume, which will lead to an increase in urination times. This is a natural thing in itself, and there is no need to make a fuss at all; For example, some friends will urinate more after drinking. Alcohol can inhibit the central nervous system from controlling urination and increase the number of urination. When alcohol is eliminated by metabolism, this urine will naturally disappear; In some cases, eating a lot of fruit with more water, such as watermelon, or the cold stimulation of sudden cold weather will also increase the number of urination. These cases should be examined first before excluding the disease factors. In fact, the simplest way to judge the increase of physiological urination is very simple. Get rid of the possible causes of increased urine output. If the frequency of urination returns to normal, there will be no problem.
3. The frequency of nocturia increased.
The increase of urinary frequency caused by kidney disease not only occurs during the day, but also changes obviously at night, especially at night, when the urinary frequency exceeds twice, the urine volume exceeds 750 ml, even exceeding the urine volume during the day. That is a sign of kidney damage, indicating that the renal tubular reabsorption function is decreased and the urine concentration is reduced.

4, hematuria
Many kidney diseases can cause hematuria, including nephritis and kidney calculi. In the early stage, urine occult blood was the main form. With the development of the disease, patients will find hematuria visible to the naked eye, and the color of urine will be obviously deepened, showing red or dark brown.
