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.
Healthy urine is generally clear and light yellow in color. The yellow is caused by urochrome pigments in the urine â a normal waste product. Urine color changes may occur due to a variety of causes, some of which are not harmful. For example, eating certain foods, such as beets, can temporarily change the color of urine to red or pink. Reduced fluid intake leads to concentrated urine, yielding a deeper shade of yellow. Urine may also appear almost colorless if you drink a large amount of water.
