It is normal to have foam when urinating. Only a few people have foam when urinating, which may contain protein. Due to the low surface tension of protein, when the content of protein in urine is high, a lot of foam may appear on the surface of urine.

At this time, if you have facial edema and eyelid edema, you need to ask a nephrologist to check your urine routine first, but most people don't need to check it. In addition, some people will have foam when urinating in a higher position.
