Thyroid is an butterfly shape gland which produces thyroxine hormone used for metabolic activities. The condition is called goiter when thyroid gland is diffused and enlarged. Goiter can be Hyperthyroid goiter ( due to high TSH levels), euthyroid goiter (due to slightly inadequate dietary iodine) and hypothyroid goiter (due to sever reduced dietary iodine).
So, if you have diffused enlarged thyroid the possibly you are having goiter.
