What is the reason for white foam in a child's urine?

Patient's question:

No

Doctor's answer:

For foamy urine, a rough judgment can be made:
1. If the bubbles are large or of uneven size and disappear quickly, this is due to some organic substances (glucose) and inorganic substances (mineral salts) in the urine, which increase its surface tension. These are normal bubbles and nothing to worry about.
2. If large bubbles disappear quickly, be alert for possible diabetes.
3. If fine bubbles float on the surface of the urine and do not dissipate for a long time, it is likely proteinuria. To differentiate, take a test tube or small bottle, fill it with 20 ml of urine, and shake it back and forth by hand. If fine bubbles form and persist, it may be suspected proteinuria. This is often seen in kidney diseases and should be taken seriously.
