What causes yellow urine?

Yellow urine is usually caused by an increase in the concentration of bilirubin or urochrome in the urine. Under normal circumstances, the color of urine is determined by urochrome (a waste product generated when the kidneys metabolize hemoglobin), ranging from light yellow to dark yellow. The following are some common causes of yellow urine: 1. Dehydration: If you do not drink enough water, your urine becomes more concentrated and appears dark yellow. 2. Dietary factors: Foods such as carrots, beets, or certain medications (such as vitamin B2) may cause temporary yellow urine. 3. Liver problems: If liver function is abnormal, such as in hepatitis or cirrhosis, the liver may be unable to effectively remove bilirubin from the body, resulting in yellow urine. 4. Medication effects: Certain medications, such as antibiotics, diuretics, or some pain relievers, can also cause yellow urine. 5. Fever or illness: The body may produce more urochrome while fighting infections or illnesses. Maintaining adequate hydration and monitoring changes in urine color can usually resolve yellow urine caused by dehydration or diet.
