I didn’t have a goiter with my Graves’, at least not something that was noticeable to me or anyone else. The medical report says it was approx. twice its normal size, however. People with either hyper- or hypothyroidism can have goiters.
I’ve also read that some people who have Graves’ have hypothyroism for a time before they go hyper–and that eventually most people with Graves’ will end up hypothyroid in time regardless of treatment choice.
