What is the reason for a little yellow urine?

Normal urine color ranges from colorless to slightly white, or yellowish, or dark yellow. Physiologically, if the patient drinks less water, the urine appears concentrated, resulting in yellow or even dark yellow urine. Of course, some patients use some pigments, which can also cause urine to show changes. For example, patients who use large amounts of carrots, or eat berberine or rifampicin, can also cause urine to turn yellow. Of course, pathological circumstances, some patients with liver disease or obstructive jaundice, will also cause urine to show yellow. Therefore, to check urine routine. If the urine routine indicators are normal, do not worry. If liver disease or obstructive jaundice patients, urine routine bilirubin and urobilin will be significantly increased.
