It is very difficult to opine on such serious matters based on vague statements like " issues with blood work on the liver "
Along with pre eclampsia
there are chances that your wife had hepatic damage in the form of HELLP syndrome
She could also have had cholestasis
ITching on the face and constipation
ARE symptoms, so its not as if she is not showing any symptoms.
Please get back with further details for assistance.
