ENDOCRIN - lithium and thyroid

lithium therapy and thyroid disease (lithium is used in treatment of bipolar disorder = maniodepression)
- goiter
- hypOthyroidism
- hypERthyroidism (rare)

The prevalence of goiter in patients receiving lithium therapy is approximately 15-20%. Up to a third of patients on lithium therapy who develop goiter (ie, 5% of all patients on lithium therapy) also may develop hypothyroidism, which usually remains subclinical. The development of clinically evident thyrotoxicosis is rare.
