Dark urine is actually urine that is very yellow in color. Dark urine has a different color spectrum. Urine may also be brown or orange or bold yellow.

What causes these types of changes is a topic that we will address in this article. It is best to learn a little about urine production first. The kidneys are responsible for making urine. When a person consumes food fluids, the associated fluids are absorbed through the gastrointestinal tract and enter the system into the arteries and pass through the arteries to the kidneys, where they are filtered and purified.

In fact, the kidneys excrete fluids as well as waste products through the urine.

Ideally, the urine should be pale yellow and very pale. In fact, if a person has very pale-yellow urine, it means that he or she is hydrated. Urine naturally has a yellow pigment called Urobilin or urochrome.

In fact, it is the pigments that cause the slight yellow color in human urine. If the urine is darker, it means that the concentration of this substance in the urine has increased.


Why does urine darken?

As we said above, the cause of yellow color in urine is due to the presence of certain pigments called Urobilin or urochrome.

If a person’s urine is dark, there are two reasons, either the amount of this substance is increased due to problems that may occur in the internal system of the body or due to dehydration, the water is less absorbed by the kidneys and causes the amount of this substance to be concentrated in the urine. The most common cause of dark urine is dehydration, but it may also be related to an internal problem that has increased urine pigmentation, for example if a person has dark brown urine, it can be a warning sign of kidney failure, which can lead to liver failure, which can cause high levels of bilirubin in the urine.

Bloody urine or very dark red urine is one of the symptoms that may be due to direct damage and direct trauma to the kidneys, so You can see that the cause of dark urine can vary depending on the underlying cause. Also, the manifestations of a dark urine depend on its underlying cause. Here are some possible causes and diagnoses that people may have due to dark urine.
