People with a bad liver will have dark circles under their eyes. The liver is one of the largest metabolic and digestive organs in the body, involved in functions such as metabolism, synthesis, detoxification, etc. If there are problems with liver function, there may be dark circles under the eyes, and there will be problems with the metabolism of toxins in the body. Patients with hepatitis, especially those with cirrhosis, will have a liver disease face, and generally have dark circles under the eyes. Dark circles under the eyes may also be caused by other reasons, such as staying up late or pigmentation from the sun, and also some other metabolic diseases, which may also cause dark circles under the eyes. To distinguish the cause, you should not assume that it is a bad liver just because you have dark circles under your eyes. Further liver function tests, imaging tests, and liver puncture biopsies are needed to confirm whether there is a disease in the liver.
