In the eyes of most people, urine is just waste after water metabolism, which is completely insignificant and does not need attention!

As everyone knows, urinating is not just "metabolic waste". In the medical field, urination is also called a health barometer. Through the state of urination, you can initially judge the health of the urinary system!

If you like to read all kinds of health science articles, you should be familiar with the typical symptom of chronic kidney disease "foam urine", which is why many people have fear after foam urine appears!

Under normal circumstances, urine is 95% water, and metabolic waste only accounts for about 5%, so the surface tension of urine is very low and the bubbles formed are relatively small.

However, after the occurrence of chronic kidney disease, due to the decline of filtration function and the increase of metabolites in urine, foam urine will appear! However, not all foam urine is "sick"!

The following three factors cannot be ignored.

1. Drink less water: As mentioned above, urine is the product of water metabolism. Only when water is normally ingested can the kidneys produce urine.

It is a hot day now. If you drink less water and sweat more, your body will be in a state of water shortage. Without water, urine will naturally concentrate, and its metabolites will occupy a large proportion, so the surface tension will change and many bubbles will be produced.

2. Impact force: If you are a male, or urinate after long-term urination, sudden release will make the urine flow have a huge impact force, especially in places far from the bedpan, and the impact force will be stronger.

When the air is wrapped in urine, a large number of large bubbles will be generated on the surface, but these bubbles will disappear soon after the urine is over;

3. The role of secretion: this is an abnormal performance that men are prone to. For men with retrograde ejaculation, long-term abstinence and wet dream's problem, semen components are likely to mix in the urethra, resulting in a large number of impurities in urine, thus changing their surface tension and generating a large number of bubbles.

In addition to the above three common factors, if there are a lot of disinfectants and detergents in the toilet, foam urine will also appear!

Foamed urine really related to nephropathy is actually called "proteinuria" clinically. The reason for this symptom is complicated, mainly because the glomerular function is damaged, and protein can not be filtered and absorbed normally, but penetrates into the original urine, which will eventually change the urine tension with the urine flowing into the bladder, so foam urine appears;

This kind of foam urine is completely different from the influence of external factors. It's like small bubbles produced by shaking coke, and it's in a very dense and delicate state.

And even if the urine has stopped, the foam will not disappear, but will last for 10-30 minutes. When you have a urine test, you will find that the urine protein has exceeded the standard! If left unchecked, patients may have many symptoms such as hypoproteinemia and edema in the later stage.

It should be emphasized that foam urine is not only a factor of kidney diseases, such as diabetes, hepatobiliary diseases and so on. , can change the shape of urine, resulting in foam and color change on the surface of urine.

Therefore, occasional foam urine is not enough to explain the problem, and long-term foam urine is not an absolute kidney injury. Only through accurate examination can the real disease in the body be diagnosed.
