It is extremely hard as a non professional (like me) to figure out what's wrong. It takes a lot of research and perseverance. But on the other hand if you persevere you will figure it out.

I'm pulling back the layers of things that went wrong one at a time. Because otherwise I simply get lost.

Hypothyroidism, as hyperthyroidism, has lots of symptoms associated with it. But there are other problems that show the same symptoms, often some problems combined. This is what makes it hard to diagnose.

Hypothyroidism is best diagnosed with the temperature test. Low morning temperature is so typical for hypothyroidism that there is little (but there is) change that it's something else.

I don't know how to best test hyperthyroidism. Do they diagnose it by looking at the amount of T3 and T4?

If Iodine is deficient and you have hyperthyroidism:
- T4 will be low, T3 will be (too) high.
- If T4 is also high then selenium could be missing too. You can figure this out by yourself by starting to take selenium. If it is selenium deficiency that's leaving your T4 high then this will make you feel more hyperthyroid because the T4 gets converted to T3. You may also get a goiter because having enough selenium in your system makes it safer for the thyroid to go looking for more Iodine more aggressively. T4 will lower in the blood and that shows on bloodtests. Your body needs more Iodine to be able to produce T4.
- The thyroid produces T3 over T4 because of the iodine shortage. It really isn't working too hard, it just is not producing any T4 because of the lack of iodine. At the same time it's overproducing T3 because of the lack of iodine.

Of course there could also be a reason the thyroid is really working too hard. By that I mean: overproducing T4 and maybe also T3. In this case adding selenium will do nothing. Maybe nodules to this? I know some cancers can do this. Sorry, don't mean to scare you, just want to be thorough.

I haven't experienced hyperthyroidism I think. I know it increases hunger because it increases your metabolism. So everything goes faster which means you need more nutrients and energy. Which means you get hungry more.

All I know is that the thyroid needs iodine and selenium and more. Not just the 125 mcg of iodine that's suggested in most sites. 125 mcg is just enough so you don't get a goiter. But the rest of the body also needs iodine. Also, it's very hard to overdose on iodine. I take a big pipette full of SSKI every morning at the moment, sometimes twice. 1 drop is 50 mg, I take at least 20 drops, so more than 1000 mg = 1 gram. Otherwise I revert back to hypothyroidism because of the bromide in my breasts that clogs up my thyroid.

I know I'm hypothyroid when my voice becomes rough, I get tired, depressed, cold, have pain in my body, my brain gets foggy.

I don't know anything about hot nodules.
