Hoppy.... There is no such thing as "completely normal" when it comes to thyroid testing. There is no black and white, and it takes a smart MD to interpret them with a critical eye instead of pronouncing everything "normal" and whipping out a script for an antidepressant. Most of them refuse to go to the trouble of thinking outside the TSH box. When I
look at your results, I don't see "completely normal" at all. Just because one MD doesn't see the same thing doesn't mean you are a hypochondriac... so forget that notion altogether. Instead of blaming yourself for feeling bad, blame him for being too lazy to figure out why!
Without turning this answer into a gothic novel, here are some things you have to consider:
job is to be a signal hormone which tells the thyroid gland to get busy and make more of its own hormones. TSH contributes nothing to making you feel bad or good. The thyroid
hormones - T4 and T3 - are the ones that regulate metabolism and cell function in every system in the body. When there isn't enough T4/T3 in circulation, symptoms appear. T4/T3 are the hormones that keep you well.
When T4/T3 are below the middle of their lab ranges, like yours are, a person can have multiple symptoms. Even though below-normal levels of these hormones are considered "normal" because they're still within the range, it does NOT
mean they're "normal" for YOU
Think about it like this: The women's "normal" range of shoe sizes is 6-10. You surely wouldn't be comfortable in a size 6 if your foot measures an 8, would you? The same goes for T4/T3... if you're like most people and need your levels to be above mid-range or higher to feel well, you certainly won't feel well if those levels are sitting at the bottom of their ranges.
Also... You have TPO antibodies. Yes, they're in range now, but they may be on the rise. It's true that some folks have a small titer of TPO antibodies and feel completely well. The small number of antibodies is apparently "normal" for them. The vast majority of healthy folks, however, have a TPO count below 2. This means that a small number of antibodies can
sometimes be "normal", but most often, no antibodies at all is normal.
You also need to have your Tg antibodies measured. These two types of antibodies - TPO and Tg, separately or together - are the most common cause of thyroid failure in industrialized nations. You might find that your Tg antibodies are through the roof. Together with that small titer of TPO, that would confirm that you have Hasimoto's thyroiditis and are headed for thyroid failure.
You have --
a) low-normal T4/T3,
b) thyroid symptoms, and
c) thyroid antibodies.
I've said this to you before, but here it is again so that it sinks in ~ There are more MDs around than ever before who are willing to treat low-normal T4/T3, even before TSH rises out of range, if there are thyroid antibodies present. The progression to full-blown hypoT is common, and they feel that treating sooner rather than later can prevent goiter and alleviate symptoms. Holistic doctors and osteopaths seem to be the most sympathetic to a treat-sooner approach than mainstream MDs.
If your doctor is not intent to find out why you don't feel well, find a better one! They're out there... but you might have to kiss many frogs before finding your thyroid prince.
But if you don't have the option of switching doctors, or the energy to do it, at least have them keep a regular check on your T4/T3 and antibodies in the near and distant future, because I would bet they'll get worse. I think you're headed for thyroid trouble that will eventually be obvious to even a stupid MD.
That's it. I'm all talked out.
