Question
I often notice foam in my urine, especially in the morning, and I have a poor appetite and a weak body. Is this foam urine proteinuria? Is it due to kidney weakness or kidney disease?
Answer
Urine contains waste products of metabolism that are useless and harmful, as well as excess substances such as water, electrolytes, urea, uric acid, creatinine, and others. This is why there is a small amount of foam, which can be said to be unrelated to disease. If you are not sure, you can combine it with a routine urine test for confirmation.
