How do I lose weight while taking lithium?
In general lithium does not cause weight gain. If you are gaining weight, I recommend that you eat less and walk more. However, be careful about too much dehydration when you exercise as this can easily lead to lithium toxicity. Lithium is not the drug you won’t to muck around with as minor adjustments in body fluids can easily lead to serious toxicity. If you do exercise, drink ample water and regularly get the lithium levels measured.
