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.
In choosing a psychiatric medication as part of a treatment strategy a physician consider different factors i.e. side effect profile, your past history of favorable response to a medication, etc. including the risk and benefit ratio of each medication. If you feel that your considerable weight gain is a problem, I would suggest a re-consult with your physician to discuss this issue. Dieting and exercise, although difficult, may be an essential aspect of your care.
