Hi -
Nine months ago I had a routine physical and my TSH level was 1.5. Last week my doctor put me on lithium (600 mg/day). I had a blood test a few days later, and my TSH level was 7! Could such a drastic increase be due to just a few days of taking lithium? If not, what else would explain the increase? There is no family history of hypothyroidism, nor do I have any systems.
Thank you for your help,
Lisa
