Yellow urine in men may be caused by low water intake, sweating, concentrated urine, taking pigmented drugs and foods, hemolysis, jaundice, etc. Because the external environment is warm, the body’s water is discharged through the skin surface capillaries, while water intake is also reduced, prompting concentrated urine resulting in yellow urine, which is often relieved by the intake of appropriate water. This is because the body has no way to absorb and decompose the pigment in a short time, and it can only be excreted through the urine when the blood flows through the kidneys, causing the urine to change its nature and become yellow to the naked eye. If you suffer from liver disease, your own bilirubin metabolism disorder will lead to increased jaundice, which will cause part of the jaundice to be excreted in the urine to form yellow urine, while the color of the urine will change after drinking more water if the color of the urine changes due to hemolysis.
