Dark urine: The kidneys are important for retaining the water you drink and preventing dehydration. When you do not drink much the kidneys reabsorb as much water as they can resulting in dark concentrated urine. When you drink water the excess water is removed and the urine becomes lighter. Other causes of dark urine can be liver disease, blood, hemoglobin or myoglobin. You can use a urinary dip stick.
