Why does our urine change colour?
In: Biology
Urine is yellow because of the waste products of red blood cell break down. Everyone will have this.
Under a normal diet, the other contents of urine are largely colorless.
People have urine of different shades because when the body is dehydrated the kidneys reabsorb water from the urine so that the yellow color becomes more prominent. If you are well hydrated or take a diuretic that makes you pee a lot (caffeine and alcohol for example), the excess water in the urine will dillute the yellow color.
Urine can also be red if you have massive muscle breakdown or bleeding in the kidney/bladder. This is not normal tho
