The term that I use is low thyroid function. Hypo is more severe. We have many here who have had low thyroid function who were not getting enough iodine who restored temperatures and felt better after fixing their iodine deficiency. Has that worked for everyone? -No. There can be complications from rT3 that will stop iodine replenishment from working, even when it has helped a particular individual in the past. That rT3 blocking can stop T4 or T4+T3 meds from working. Given the complexities that can occur, I suggest that you not go with absolutist statements from others. You will need to experiment to see what works for you. The best first step is to eliminate a [suspected] iodine deficiency and see how your body and mind respond. Sometimes things cannot be easily fixed and medications are needed and one’s labs mean that most doctors will state that you are normal and do nothing.
Avoid running with implications of what you read for full blown hypothyroidism as this may be misleading with low thyroid function [sub clinical]. I do stress that low thyroid function slows down every cell in the body and can compromise many functional systems. All the more reason to make sure that your thyroid function is good.
Early stages of adrenal fatigue can involve higher levels of cortisol as a maladaptive stress response. But the adrenals start to fail and and things go down hill from there. Given the complexities, I suggest that people read Wilson’s book on adrenal fatigue.
