DEAR DOCTOR K: I sometimes have dark, strong-smelling urine. Should I be concerned?
DEAR READER: Given that this happens only occasionally, it probably is not something to worry about. But before reassuring you, I would need answers to some questions: --By dark, do you mean dark yellow? Or is your urine brown or red? If your urine is just a dark yellow color at times, especially when you don't drink enough fluids, then you don't need to worry. Dark yellow urine is a sign of dehydration.
