Why is my face yellow even though I don't have hepatitis A, B, or C?

Pale yellowish complexion may result from various factors. Although viral hepatitis such as hepatitis A, B, and C have been ruled out, other potential causes still need to be considered. A yellowish complexion might be physiological, such as from chronic lack of sleep, excessive fatigue, dietary effects, sun exposure, or oily skin. It could also be pathological, such as malnutrition, anemia, depression, liver dysfunction, jaundice, gallstones, or hookworm disease—these conditions may cause metabolic disturbances in the body, thereby affecting skin appearance.

It is recommended that the patient seek medical attention promptly and undergo detailed liver function tests, including serum bilirubin, liver enzymes, alkaline phosphatase, and gamma-glutamyl transferase (GGT) levels, as well as imaging examinations such as ultrasound, CT scan, or MRI to evaluate the liver, biliary tract, and pancreas. Additionally, physicians may recommend more specialized tests, such as liver biopsy or endoscopic retrograde cholangiopancreatography (ERCP), to further clarify the diagnosis.
