Introduction
Most cases of dark yellow urine are not related to the liver. For example, insufficient water intake leading to concentrated urine, or consumption of carrots, vitamin B complex, or certain medications, can all cause darker urine. In such cases, adjusting diet and water intake usually returns urine color to normal. If liver function is impaired, abnormal bilirubin metabolism may increase bilirubin levels in the urine, causing the urine to appear dark tea-colored.

Generally speaking, yellow urine is not necessarily an indication of liver problems and may be caused by various factors; however, abnormal liver function can also lead to changes in urine color. If concerned, it is advisable to seek medical consultation in advance. Detailed analysis is as follows:

In most cases, yellow urine is unrelated to the liver. For example, insufficient water intake can lead to concentrated urine, or consumption of carrots, vitamin B complex, and certain medications can darken the urine color. In such cases, adjusting diet and water intake can return urine color to normal.

If liver function is impaired, abnormal bilirubin metabolism may cause increased bilirubin levels in the urine, resulting in dark tea-colored urine. This may also be accompanied by symptoms such as yellowing of the skin and eyes, and reduced appetite. Such cases warrant attention for potential liver issues.

If yellow urine persists along with other discomforts, self-diagnosis should be avoided. Prompt medical tests and examinations are necessary to determine the cause accurately and take appropriate actions accordingly. Do not handle the situation blindly without professional guidance.
