With regard to iodine, it sounds like you're doing wonderful! From what I understand, it appears that now the iodine is staying with your body and having impact, rather than swooshing straight through like it was on your first test. Good job!
Your menopausal symptoms sound like a combo of hypothyroid, adrenal insufficiency, and hormone imbalance. It's a chaotic topic, but worthwhile investigating. Here are some beginning points.
My husband can have an increase in blood pressure if he gets too much, so I think it's possible for some people. That combined with the rise in cholesterol suggests a hypothyroid condition that bears looking into. If you get blood work, free T3 and free T4 are what you're looking for. Some people have been able to tune up their thyroids to resume normal function, but I needed Natural Thyroid Hormone such as Armour. BTW, in modern cardiac thinking, a bp of 115/74 is desirable, not low.
