isn't foamy/bubbly urine a sign of kidney dysfunction? I have dysbiosis and maybe a yeast overgrowth but also have adrenal issues and its hard to separate what is causing what. But i do have foamy urine and noticed my blood is probably full of toxins as i keep getting canker sores continually in my mouth, sores on my skin, etc. Is foamy urine just the kidneys taking a huge load from the toxins from candida or is it a concern for kidney disease? Foamy urine usually means protein in the urine.
