Jaundice is known as yellowing of the skin, mucous membranes or eyes due to a high concentration of bilirubin in the blood. Thus, normal numbers of bilirubin are 0.3-1 mgr / dl, while jaundice is detected when serum levels are greater than 2 mgr / dl. Bilirubin is the product that is obtained from the disintegration of the red blood cells of hemoglobin and may increase because of various diseases of the liver, gallbladder, pancreas or blood. Bilirubin sits in the tissue and causes the skin, mucous membranes and membrane of the eye (sclera) to turn yellow. This can occur when liver is damaged by a virus (different hepatitis), gallstones, blood disorders, pancreatic cancer, accumulation of bile in the gallbladder, for example during pregnancy (jaundice of pregnancy).
