Causes of yellow eyes include conditions such as cirrhosis, bile duct obstruction, pancreatic cancer and blood disorders, such as sickle cell anemia and incompatibility reactions from a blood transfusion, states Healthline. Concentrated urine, dehydration and liver diseases can cause dark urine.
Yellowing of the eyes mainly occurs from gallbladder, pancreas and liver conditions and is a symptom of jaundice, notes Healthline. Jaundice occurs if a portion of the process of the breakdown of hemoglobin into bilirubin does not take place, causing excess bilirubin to accumulate in the skin and giving the skin and eyes a yellowish cast.
Dark urine can indicate that a person is not drinking enough fluid, reports WebMD. This condition can also indicate circulation of unusual products in the body, such as bile products, explains Healthline.
