Abstract
1. Intravenous glucose tolerance test were performed in fourteen patients with mild or moderate liver damage due to paracetamol overdose. 2. In patients managed conservatively there was glucose intolerance associated with a diminished early insulin response to glucose, suggesting inadequate nutrition in the period between the overdose and the glucose tolerance test. 3. Patients given intravenous glucose supplements to maintain nutrition were also glucose intolerant and, in these, insulin responses to glucose were normal. The decreased fractional disappearance rate was partly due to an increase in glucose distribution space and partly due to a decrease in absolute glucose disappearance rate. 4. Impaired gluconeogenesis was suggested by mild fasting hypoglycaemia in four patients and raised fasting blood lactate concentrations. Serum growth hormone concentrations showed a paradoxical increase after glucose. 5. All these variables had returned to normal in four patients re-tested after recovery.
