Dark Urine – Is It Bad?

Usually people don’t discuss such topics, even with the nearest one, but it still remains an important thing as the colour of your urine can show you that something inside of your body is going wrong.

In healthy people, the color of urine varies from orange to straw-yellow. Coloration depends on the amount of urinary pigment in the urine – urochrome. Expression of color can depend on the part of the day. If the dark urine persists for a long time, it can indicate the presence of some pathological process inside you.
