I just want to throw this out there.
Before you go cutting body parts as Baby Genius (@unreal24278) has suggested you will need to figure what is causing your problem.
Graves is the most common cause but there is also iodine induced hyperthyroidism. Etc…
You may be able to control with your diet.
I think we are kinda in the same boat. It’s screwed up enough to cause problems, but not severe enough to warrant drastic measures. I consider cutting out body parts a drastic measure. When I have a severe episode, it seems like it gives it all it has and then crashes. It’s like it blows up and releases all the hormones at once then it dies for a while and I become severely hypo. My doc ( which I shit canned) said no, it doesn’t. Uh… I know how I feel. I have learned to deal with the slightly hyper way better than the hypo. I have dealt with it for so long it’s part of my personality. I can’t deal with being a slug When my legs are so heavy it takes effort to put one foot in front of the other.
For the most part I function pretty well. There is usually an event that triggers a full blown episode. The last time was a wasp sting. The time before that bug spray.
I’m learning how to control it with the supplements. The carinitine, glutamine, bugleweed, lemon balm, CBD oil. Etc…
I guess what I am trying to say is… do some research first. Consider all the options. Keep a diary of you eat, and do to see if you can pinpoint what brings it on.
I can’t see putting my fate in the hands of somebody who won’t even listen to me.
