Answer:Dehydration

Explanation:

Dark urine is usually indicative of dehydration; but there could be more reasons responsible for it. Ideally, when you eat or drink something, it goes through your digestive tract, circulatory system and then to your kidney. Kidneys are where everything is filtered and urine is produced. Urine contains the harmful toxins which need to be eliminated from the body. Darker urine is more concentrated. It is indicative of the fact that unnecessary toxins and wastes are circulating in your body which could mess with your health. This, again, depends on how much fluids you drink throughout the day. But there could be many other reasons responsible for the same.
