Four of the medications you are taking may cause weight gain
Lithobid, Depakote, Neuronitn, and Risperdal. Celexa (citalopram
) has been reported to cause both weight loss and weight gain, but is less likely than the other agent to cause your weight gain.
You are also taking Synthroid, which may indicate a history of hypothyroidism. An under active thyroid can also cause weight gain. It may be helpful to have a laboratory test done to check your thyroid function.
