What is a characteristic finding in urine that may indicate dehydration?

Dark yellow urine is a characteristic finding that often indicates dehydration. When the body is dehydrated, the kidneys conserve water, leading to a more concentrated urine that appears darker in color. This darker tint is a result of the higher concentration of waste products and pigments, particularly urochrome, which gives urine its color.

In well-hydrated individuals, urine is typically lighter in color due to a larger volume of water diluting its constituents, resulting in pale or colorless urine. Conversely, cloudy urine may suggest the presence of bacteria, crystals, or other substances but does not specifically signal dehydration. Therefore, dark yellow urine is a clear indicator of concentrated waste due to insufficient fluid intake, making it a significant marker for assessing hydration status.
