What causes male foam urine?

The reasons for foaming urine in men are as follows: 1. Urgent urination. If the urine is held for too long, the urine will be discharged urgently during urination, and the urine will mix with the air and violently impact the liquid surface, which can form foam. Standing too high during urination will also cause the urine to show foam, but the foam will normally dissipate quickly. 2. Excessive concentration of urine. When the human body sweats too much, drinks too little or frequent diarrhea, the water in the human body is insufficient, which can cause urine concentration, so that the protein and other components in the urine increase, which can cause foam urine. 3. If you suffer from kidney diseases, such as glomerulonephritis, diabetic nephropathy, etc., it will cause kidney function damage, and it is easy to cause foam urine.
