A condition in which urine appears pale or white instead of its normal straw-yellow color. The whiteness usually comes from excess phosphates precipitating in alkaline urine, from chyle, a milky lymphatic fluid leaking into the urinary tract, or from heavy pus in severe urinary infections. While often harmless and related to diet or hydration, persistent milky urine warrants medical investigation, since chyluria can signal parasitic infection or lymphatic obstruction. For nutrition professionals, urine color is a rough hydration gauge: very pale urine typically means generous fluid intake, while dark urine suggests dehydration, though vitamin supplements and certain foods can tint it independently. Albinuria itself is a sign rather than a disease, and its significance depends entirely on what is making the urine white.
