Does normal people's urine have foam?

Some people have heard that there is foam in the urine, which is proteinuria, so they will feel very nervous. In fact, normal people's urine sometimes has foam. This does not necessarily mean that it is proteinuria. Formal examination is needed to determine whether it is proteinuria. Once proteinuria occurs, it means that there is a problem with kidney function, and even some more serious manifestations may appear. Let’s take a look at this aspect.

Does normal urine have foam?

Proteinuria is mainly determined by urine routine and urine protein quantitative testing. Foamy urine can only be used as a simple method of self-observation when the presence of urine protein has been confirmed. The test results should still be the final word.

People usually associate foamy urine with proteinuria, and even equate them, thinking that if there are bubbles in their urine, their kidneys are not in good condition. In fact, this is unscientific. Foamy urine is not always proteinuria. Usually there will be foam after people urinate, but the foam is usually large or small and disappears after a while. At this time, the urine test is often negative for protein. Foamy urine. Sometimes urine tests indicate proteinuria. At this time, the urine foam is mostly small and uniform, and the surface looks greasy and shiny, and it is difficult to dissipate for a long time.

What kind of bubbles don't need to be nervous?

1. It is inevitable that normal people will produce some foam when urinating. This is a normal phenomenon because urine contains a certain amount of organic and inorganic substances. These substances will make the urine tension stronger, thus causing foam.

2. If you drink less water or the angle and speed are different when urinating, some foam will be produced.

3. Some people overeat and consume a large amount of protein-containing food at one time, which will also cause foam in the urine.

4. Some people may also experience transient proteinuria due to strenuous exercise, mood swings or standing for a long time.

How to identify true proteinuria?

The formation of foam in urine is due to the high surface tension of the liquid. The higher the surface tension, the more foam is formed. If the composition of urine changes, such as an increase in protein, mucus and organic matter, the surface tension will increase. Generally speaking, if the bubbles are large or of varying sizes and last for a short time, they are considered normal bubbles. This foamy urine does not necessarily mean that there is something wrong with your body, so there is no need to worry.

If there is a layer of fine foam floating on the surface of the urine and it does not dissipate for a long time, it is likely proteinuria. The best way to identify it yourself is to take a test tube filled with 20 ml of urine and shake it back and forth with your hands. If small bubbles that do not dissipate for a long time appear on the surface of the urine, it is suspected proteinuria and you should go to the hospital for further examination and diagnosis in time.
