Morning urine foam, no foam during the day, what's going on?

Morning urine foam during the day without foam reasons generally include proteinuria, intermittent proteinuria, microproteinuria, etc.

1. proteinuria

proteinuria refers to a large amount of protein in the urine, usually plasma protein, due to kidney filtration dysfunction or other reasons, resulting in protein penetration from the blood into the urine. Morning urine foam more, less during the day, may be because the night sleep time is long, kidney filtration more protein, and more activity during the day, kidney filtration less protein.

2. intermittent proteinuria

When glomerular filtration membrane function is damaged but not completely damaged, most of the protein can be filtered, which may lead to discontinuous proteinuria, which is easy to cause the above symptoms.

3. microproteinuria

Microproteinuria refers to protein content in urine lower than normal levels, but still higher than normal levels. Morning urine foam, may be because of long sleep at night glomerular filtration into urine caused by trace protein. And frequent urination during the day, there will be no foam urine.
