What are some possible causes of yellow eyes and dark urine?

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.
