What does a man's urine foam say?

Men's foam can be seen in normal physiological phenomena, but also may be caused by pathological changes. Generally, when men urinate, urine will fall from a height, which will cause foam in urine; if the foam in urine will disappear after standing for a period of time, it is normal. This situation does not require special treatment and has no effect on the body. Men show frothy urine after urination, and frothy urine cannot disappear by itself after standing, so it is necessary to consider whether there is urine protein. This situation may be caused by kidney diseases such as nephrotic syndrome and glomerulonephritis.
