On the "subclinical hypothyroidism", I wanted to add what I heard from Dr. Ken Berry, who has videos on YouTube talking about Thyroid issues, misdiagnose, medication options, etc.

He mentioned seeing patients who said "my doctor said -- yes my TSH3 is high, but because my FT3 and FT4 are within range, he said I don't need to take any medication (...or I don't need to take it permanently)."

Dr. Berry says that's a misunderstanding.

The FT3 and FT4 ranges are only suggestions, but each person is different.

You could be within range on FT3 on the low scale, and to one person they would be fine and have no symptoms.

Another person, they would feel sluggish and not performing at their optimal level.

So the ranges are only a guide, and the endocrinologist should be looking at symptoms as well, not just as the blood tests.

He compared ranges to driving a Toyota Corolla vs. a Ferrari. Like yes, you're not dying, you're still able to function somewhat. But it doesn't mean just because you're within range, you're at your optimal performance, where your body needs to be personally.
