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.
A Discovery Health answered. If your urine is any color other than yellowish-orange, yellow or clear-you could have a serious medical condition. Very dark orange, reddish or brown urine, for instance, likely has blood in it and could be a sign of infection. There are some prescription drugs, however, that can change the color of your urine simply by passing through your system.
