Hello,
Dark circles under the
eyes can be caused by many things -but it usually indicates that
your body is under stress from something. It can be caused by anemia, loss of sleep, allergies, malabsorption (intestinal problems causing low vitamin and mineral absorption), and liver conditions to name a few. The fact that you have other symptoms with it indicates the need for blood tests that look for signs of infections, intstinal parasites, liver problems, or nutritional deficiencies.
