What is an Under-Stimulated Thyroid?
What does it mean when they tell you your thyroid is not being stimulated?
I can't tell from your description exactly what your doctor was trying to tell you. Normally the thyroid gland must be stimulated by a hormone from the pituitary gland called "Thyroid Stimulating Hormone" in order to work correctly. A patient who had a pituitary disease causing a deficiency of thyroid stimulating hormone might be told that the thyroid was "not being stimulated." However, this is a fairly rare cause of an underactive thyroid. In most cases, an underactive thyroid is caused by disease in the thyroid gland itself, and not by lack of stimulation. I suggest that you get further clarification from your doctor.
