It is understood that about 20% of patients with liver disease have pigmentation around exposed parts such as face and eyes, showing "dark circles". 2, irregular menstruation. For women, there may be more people with dark circles, but if dark circles persist for a long time, they may be caused by dysmenorrhea or irregular menstruation.
