I am a newbie and found this site by a good luck chance! Had thyroid removed apart from lower left lobe 30 years ago. Does this mean I can't have Hashimoto's? I am very unread on the whole thyroid removal implications. I am currently taking 100mg of Levo and this has gone up and down over the years. I'm a layman with T3 T4 etc. My GP has never mentioned anything other than my results are too high or too low! Beginning to feel very annoyed with myself for not finding out about all the side effects 30 years ago. I have osteoporosis, depression, high cholesterol and blood pressure. Not a pretty picture!!!!! Any advice would be highly appreciated.
