6. Yellowing of the Skin
Liver problems such as hepatitis or cancer, could also be gallstones. A yellow-tinged pallor is often caused by an excess of bilirubin in the system. Bilirubin is the yellow substance that occurs when dead blood cells break down in the liver. Yellowing can also happen in the eyes.
Newborn babies often have jaundice or yellowing of the skin because they produce more bilirubin than adults. When adults have yellowing, it is most often due to a larger condition that typically involves the liver such as Hepatitis (A, B and C are the most common types), liver cancer, or alcohol abuse that has led to cirrhosis or scarring of the liver.
