The color of urine is a very important characteristic that laboratory technicians pay attention to first of all. A special pigment, urochrome, gives the urine of a healthy person a specific shade, which can vary from light yellow to saturated amber. In this case, the liquid emitted must be transparent and not contain impurities. Deviation from normal color does not always indicate a malfunction in the body, however, with the exception of natural causes, dark brown urine is a symptom of serious pathological changes.
Natural causes of dark urine
Complaints about a change in the shade of urine are a common occurrence in people of different ages. To determine the main cause of such changes, it is necessary to take into account the products that the patient eats.
Urine of a dark brown color is observed after consuming legumes, rhubarb, aloe and black tea. In addition, darkening of urine can provoke some medications, rare urination and intense thirst.
Pathological factors of urine color change
With liver disorders such as hepatitis and cirrhosis, urine turns brown as a result of exposure to bilirubin and biliverdin - specific dark pigments. Another sign of such diseases is the formation of yellow foam when shaking urine. With kidney damage, namely with urolithiasis, tissue is injured by solid inclusions, which leads to the appearance of blood in the feces. Urine of dark brown color with purulent inclusions is observed with the development of tumors of the genitourinary system. It should be noted that a similar phenomenon can occur with infectious diseases such as pyelonephritis, urethritis and cystitis.
If you have brown urine, the causes of which are pathological in nature, it is recommended to urgently visit a doctor, otherwise possible complications can lead to very serious consequences.

Often, dark-brown urine indicates serious pathologies such as marching and sickle cell anemia, thalassemia, Markiafava-Miquelli's disease, and syphilitic and hemolytic disease in newborns.
