hi. noted history of jaundice. does your father experience any other symptom like abdominal pain, nausea, vomiting, weight loss? jaundice can be caused by infective or obstructive causes (stones or tumor lesions). it is best if you consult with a doctor, preferably a gastroenterologist or a general surgeon, for physical examination and clinical evaluation. diagnostics (such as ultrasound, bilirubins, alkaline phosphatase, etc.) and management (medical and/or surgical if indications are found) will be directed accordingly. malignant causes must also be ruled-out. hope this helps. good day!! ~dr.kaye
