The formation of foam in urine is caused by the high surface tension of liquid. The higher the surface tension, the more foam is formed. Human urine contains not only most water, but also a very small amount of foam. However, if the composition of urine changes, such as protein, mucus content and organic matter increase, the surface tension can be increased.

Therefore, there are a lot of bubbles in urine, which generally have the following situations: (1) renal lesions or increased urethral secretions, and the exact cause needs further examination and determination. (2) It is normal to stop sexual life for a long time, frequent nocturnal emission, or frequent excitement to increase the mucus secreted by urethral bulbar gland. (3) Some people have gas-producing bacteria in their urinary tract, which can produce bubbles in urine, which is different from foam.

It can be seen that bubbles are not short of elements. I think you should be in the second and third cases, and the possibility of proteinuria is very small.

Don't be nervous if there is foam in your urine.

Some people are very nervous about the foam when urinating, and feel different from normal people, for fear of getting sick. In fact, sometimes it is normal to have bubbles in your urine.

Only a few people have foam in their urine, which may contain protein. Due to the low surface tension of protein, when the content of protein in urine is high, many bubbles may appear on the surface of urine.

Therefore, if there are other symptoms of kidney deficiency at the same time, you need to ask a nephrologist for a detailed examination. Most people don't need to check.
