Glucose tolerance and serum lipids in man after long-term lithium administration.

Intravenous glucose tolerance and serum lactate concentration during the tolerance test were determined in the same 12 patients after 6 months of placebo and after 6 months of lithium treatment. At the end of these periods values of glucose, lactate, serum free fatty acids, and serum triglycerides were measured in fasting patients. Long-term lithium treatment had no influence on these parameters.
