Urine is yellow all the time. Why?

Very yellow urine is generally caused by dietary factors or liver diseases and blood diseases. The urine excreted by normal humans is transparent and pale yellow, while morning urine has a higher concentration of solutes in the urine due to the lack of drinking water for a long time at night, so the color will be darker. First of all, the color of urine excreted will be changed by personal diet and ambient temperature changes. For example, taking a large amount of vitamin B2, carotene or high ambient temperature and sweating will lead to yellow urine. Insufficient daily intake of water will also lead to concentrated yellow urine. Secondly, if urine has been yellow for a long time, it is necessary to consider the causes of urinary tract infection or liver disease and blood system disease. Urinary tract infection is due to pathogenic bacteria caused by urinary tract infection disease, in addition to yellow urine symptoms, normal also accompanied by urgency, urinary pain, etc., through urine routine examination can be diagnosed. If it is liver disease or blood disease, resulting in abnormal bilirubin metabolism from urinary tract discharge, discharge urine color will be darker, or even brown.
