Why is there so much foam in my urine at night?

There is more foam in urine at night, generally because people drink less water at night, resulting in a relative decrease in water content in the body and a corresponding decrease in urine production. Therefore, the content of impurities in urine will be more, resulting in yellow urine. And there are more bubbles in urine, especially when urinating. If urine falls from a height, the bubbles in urine will be more obvious. In this case, we can let the urine stand for a period of time. If the urine is allowed to stand for 10 to 20 minutes, the foam can disappear by itself, which is normal. However, if the urine is soaked for more than half an hour, the foam still does not disappear. This situation may be that the urine contains protein. It is necessary to check the urine routine in time to determine whether there is any pathological change in the urine.
