Episode notes
Why Urine Is Usually Yellow
- Urine mainly contains water, mineral salts and nitrogenous wastes like urea and uric acid.
- Urobilin, produced from bilirubin, gives urine its yellow shade which varies with hydration.
Hydration Controls Shade Intensity
- Hydration dilutes urobilin so more fluids produce clearer urine and less fluids produce darker urine.
- Urine colour therefore reflects recent fluid intake and concentration levels.
Colour Clues: Foods, Drugs, Or Disease
- Unusual colours can signal food, supplements, or medical issues like infections or hypercalcemia.
- Examples include red from blood or beetroot, blue/green from asparagus or infection, and fluorescent yellow from vitamins.
