Dark yellow urine is a sign of dehydration. Your urine is dark because your kidneys are doing what they are supposed to do when you are dehydrated: conserving water by making less urine. If this is the case, drink more water â eight 8-ounce glasses each day.
Dark urine is most commonly due to dehydration and concentrated urine. However, it may be an indicator that excess, unusual, or potentially dangerous waste products are circulating in the body. For example, dark brown urine may indicate liver disease due to the presence of bile products. Bloody (reddened) urine is an indication of many other potential problems, including direct injury to the kidneys.
