There are numerous possible reasons for more foam in the morning urine: 1. It is related to excessive concentration of urine. Because the night has not been urinated, and the night has not been rehydrated, the urine is concentrated, the concentration in the urine solute is relatively high, and the process of urination produces more foam due to the effect of shocking factors, which is not a pathological phenomenon. If more water is consumed appropriately, the urine color changes to clear and the foam decreases during urination, it may be related to concentration. The urine specific gravity can be checked routinely, such as the specific gravity is too high can also appear excessive urine foam. 2, urinary tract infection, showing increased urinary protein, or various types of kidney disease, resulting in increased urine protein content, can also lead to more foam protein in the urine, in the process of urination to produce shock effect and produce more foam. In this case, it is recommended to perform qualitative or quantitative urine protein examination, and if the urine protein content is increased, the foam increases, which is related to the elevated protein content. 3. Elevated bilirubin and urobilinogen in the urine can also lead to increased urine foam, and it is recommended to perform routine urine examination.
