Lithium carbonate and weight gain.

E D Peselow, D L Dunner, R R Fieve

    Journal of Affective Disorders

    Summary

    Lithium treatment in bipolar patients can cause significant weight gain. This study found lithium-treated individuals gained more weight than those on placebo over 12 months.

    Area of Science:

    • Psychiatry
    • Pharmacology
    • Metabolic Research

    Background:

    • Lithium is a common mood stabilizer for bipolar disorder.
    • Weight gain is a frequently reported side effect of lithium therapy.
    • Understanding the direct impact of lithium on weight is crucial for patient management.

    Purpose of the Study:

    • To evaluate the incidence and extent of weight gain in bipolar patients undergoing lithium treatment.
    • To compare weight changes in lithium-treated patients versus those receiving a placebo.

    Main Methods:

    • A 12-month prospective study comparing 21 bipolar patients on lithium with 12 bipolar patients on placebo.
    • Both groups maintained euthymic mood throughout the study period.
    • Weight changes, including absolute weight gain (>10 lbs) and percentage body weight gain (>5%), were meticulously recorded.

    Main Results:

    • Significantly more lithium-treated patients gained over 10 lbs compared to placebo (11/21 vs 1/12).
    • A higher proportion of lithium patients experienced a 5% increase in total body weight (13/21 vs 2/12).
    • These weight gain differences were statistically significant (P < 0.05).

    Conclusions:

    • Weight gain appears to be a direct consequence of lithium treatment in bipolar disorder.
    • The findings underscore the importance of monitoring weight in patients prescribed lithium.
    • Further research may explore mechanisms and management strategies for lithium-induced weight gain.
