Cindy, this can be true, because during the progression of Hashimoto disease the thyroid eventually bcame just a cluster of dead cells and scar-like tissue as a result of destruction by the own immune system
I have a multinodular goiter and most likely Hashimoto's (based on TGa antibodies). I have a dominant nodule that measures over 1.5 cm. according to the ultrasound. My endo says it's not a nodule, but the remaining "good" part of my thyroid. I'm really uncomfortable with that explanation and have scheduled a second opinion at Moffit Cancer Center. Better safe than sorry in my opinion.
I really hope that you get the answers you need soon.
Cindy
Sadly Hashimoto's is like a car that needs servicing but you just can't afford to fix it. Sometimes it'll run real fast and other times let you down by running real slow. The poor old thyroid has a hard time of knowing what is going on because the Hashi's is attacking it. So it splutters along trying to do what it thinks is best, till it collapses. That can take years of misery for some people. (My self included!) For others there is no obvious problem. Everyone is different in how the body reacts.
Often with Hashimoto's disease a person will get 'lumpy bumpy thyroids' Again it is the thyroid trying to act normal whilst under attack. In fact as many as aver 75% (I can't recall the exact figure but it is high) of the normal population have lumpy bumpy thyroids with no ill effects.
Hashi's will often produce Multi-nodular goitre Meaning a large number of lumpy bumpy bits. For most people that is not a problem. The scan will give a good idea what is going on, and if a biospy is needed then that is also a great way of assessing the situation.
Personally I had at least a year of being hyper, (was great lost a ton of weight! but felt proverbially down) then had at least 5 years hypo, (yucksville) Then went back to hyper for a year, then about 3 years hypo. My sister has Hashi's also, and she has been hyper pretty much all her adult life.(She's 38) Others I know say they go months one and months the other. There is no set rule.
I hope that didn't confuse you even more, but really every one is different. Would be great if it were the same for everyone, then we could all be treated the same, and the doctors would believe us of our condition.
Cheers!
