What color of urine occurs in liver disease?
Liver and bile diseases such as hepatitis, cirrhosis of the liver or jaundice (icterus) as a result of gallstone disease can lead to darkening of the urine. The urine can take on a yellow-orange to brownish color. In addition, this can be caused by metabolic disorders such as porphyria (impaired heme biosynthesis).
In the case of gallstone disease, the cause of the dark coloration is that the bile pigment bilirubin is no longer excreted through the intestines due to the obstruction of the bile ducts. As a result, it is increasingly released through the urine and causes a dark discoloration. On the other hand, the stool loses its dark color.
What does urine color look like in case of renal failure?
Patients affected by acute renal failure often have little or no urine left to pass. Depending on the cause and the course of the disease, however, it can also lead to polyuria, i.e. greatly increased urination. As a result, the urine may be either lighter or darker and the amount may vary.
A change in the color of the urine in a chronic event takes place gradually. Kidneys can no longer concentrate the urine, so it is usually light or not very colored. If unspecific symptoms such as exhaustion, tiredness, water retention or loss of appetite occur over a longer period of time, chronic renal insufficiency may be a possible cause and the symptoms should be clarified by a doctor.
