I am finding that there is no longer agreement on this topic among doctors. Within my enodo practice there are four drs. There is no agreement within. I am told that if you take Thyrogen, the LID isn't necessary. LID just makes your body hungry for the iodine and aids in the hypo state. My endo let me use thyrogen but insisted I stay on the LID until my WBS. I'm on my last day od isolation now. Are you taking thyrogen?
