if your urine is dark amber in color and has a strong odor too it may indicate that it's extremely concentrated. this can happen after heavy exercise and sweating and means that you need to drink more water to avoid dehydration. if the extra water intake doesn't lighten the color and odor of your urine you may have other conditions that require medical attention such as a urinary tract infection or even early diabetes. sometimes foods cause urine to have an odor (asparagus for example) but the odor should go away after a few hours or overnight. if a strong odor persists it's time to contact your health care provider and have a urine test to determine the cause.
