 to the overall thyroid. A lot of times, we go right after the thyroid because it's slow or whatever's going on, and we don't look at the pituitary gland to see if it was more of a root cause of the situation. So that's another one to look into as well. But I wouldn't lose hope. I definitely would not. And your diet makes a key role in this. You've got to look at your lifestyle factors. There are some genetics, but a lot of times it's deficiencies.
