Yellowing of the skin all over the body is a very common symptom and the first thing the patient needs to do is to identify when this symptom occurred and how long it has lasted. If the yellowing of the skin all over the body occurs in early childhood, it is considered to be more influenced by genetic and congenital factors. If the yellowing of the skin appears suddenly over a short period of time, it is presumed to be related to pathological changes, suggesting the possibility of liver disease or gallbladder disease.
