I don't think a flu can cause yellow eyes. It can just cause red and watery eyes as symptoms of a cold. As to the yellow eyes, we are not talking about the yellowish deposit or spot in eyes, the cause is jaundice surely. Jaundice refers to a condition that the bilirubin built up in the blood. Bilirubin is coming from the breakdown of old red blood cells. It is processed by liver and then through the gallbladder into small intestine with bile to help digestion. It would finally be eliminated out in excrement. If there is something wrong with liver, gallbladder or blood, you might get jaundice which would cause yellowness of skin, sclera and mucous. Is there any other symptoms accompanied the yellowness of eyes? If you got fever which is also a common symptom of a flu, it might be caused by acute cholangitis, hepatapostema, septicemia, and virus hepatitis. If jaundice is accompanied with severe pain at the stomach pit, it might be caused by gallstone. No matter what problem caused the jaundice, you should go to hospital at once to test your blood or liver or gallbladder, because it is serious emergency which requires immediate treatment.
