After urinating, there is a layer of small foam floating. What's going on?

A small layer of foam floating after urinating may be caused by too little drinking water, glomerulonephritis, nephrotic syndrome and other reasons.

1. Drinking

too little water at ordinary times may cause urine concentration, urine moisture reduction, resulting in changes in urine components, at this time there will also be symptoms of urine foam.

2.

Pathogenic microbial infection of glomerulonephritis can cause glomerulonephritis, inflammatory lesions in kidney tissue, inflammatory stimulation can cause glomerular filtration function to decline, causing urine foam symptoms.

3. Nephrotic syndrome

patients with nephrotic syndrome, may cause renal function decline, unable to play normal filtration function, resulting in protein and urine together with excretion, urine foam may appear.
