Hmm, if your urine is especially foamy, it can be a warning sign for kidney problems, the foam is proteins that aren’t filtered out and retained in the bloodstream properly by the body, because the kidneys aren’t working great. I get it sometimes when I’ve been exercising a lot and loading on protein, and it’s a sign to ease up and drink a bit more water.
“Relationship between Kidney Disease and Foamy Urine
A healthy kidney filters waste and toxins from your blood while keeping protein and other important substances that your body needs circulating in your bloodstream. However, when your kidneys are damaged, they can allow too much protein to pass through into your urine. This is called proteinuria. As stated above, the high levels of protein in urine can cause it to be foamy. Protein in urine is not a problem itself, but it can be a sign that something is wrong. If you have a family history of kidney disease, diabetes, or high blood pressure, talk to your doctor about getting tested for CKD.”
