 The usual symptoms in the mother are non-specific including nausea, vomiting, anorexia (or lack of desire to eat) and abdominal pain; excessive thirst may be the earliest symptom without overlap with otherwise considered normal pregnancy symptoms; however, jaundice and fever may occur in as many as 70% of patients.In patients with more severe disease, pre-eclampsia may occur, which involves elevation of blood pressure and accumulation of fluid (termed oedema).This may progress to involvement of additional systems, including acute kidney failure, hepatic encephalopathy, and pancreatitis.
