Does black rings under your eyes have some thing to do with the kidneys?

While dark circles under the eyes can sometimes be a sign of an underlying medical condition, they are not typically associated with the kidneys. Common causes of dark circles include genetics, aging, fatigue, dehydration, and allergies. If you are concerned about the appearance of dark circles under your eyes, it is always a good idea to consult with a healthcare provider to rule out any underlying medical problems and discuss the best course of action.
