Insanely high TSH levels

What does a TSH level of 22+ IU/L actually imply? I'm wondering what this could signify—assuming it doesn't mean I'm looking at lifelong medication and constant struggles. I'm not entirely sure what the standard reference range is, but it seems like things have moved past the "worrying" stage and are starting to escalate. I don't have my T3 or T4 levels yet. Bring it on, I guess. Is this likely hypothyroidism?

neonheron12 said:Probably hypothyroidism?

Most likely, but you can't know for sure without seeing the actual clinical results. It could just as easily be secondary hyperthyroidism.

James Watson84 said:That’s possible, I suppose, though nothing is certain without looking at the full clinical picture.

I think I'll get my blood work done again. These results are a bit outdated since they're from about four months ago (I actually forgot to pick up the report because I wasn't expecting anything unusual back then 🙂)

James Watson84 said:It could potentially be secondary hyperthyroidism.

But isn't it more common for patients to have low, normal, or slightly elevated TSH levels?
I'm hoping it isn't something like a pituitary tumor somewhere up there. 😕

neonheron12 said:So why isn't everyone else seeing low, normal, or slightly elevated TSH levels?
I mean, unless I've got some random pituitary tumor hiding somewhere. 😕

It's hypothyroidism 99.9% of the time. Cases where the body just pumps out TSH on its own—causing secondary hyperthyroidism—are incredibly rare (in those cases, TSH stays high, sometimes by insane amounts). Sure, TSH can spike due to other conditions, but honestly, that’s mostly academic stuff at this point. Don't sweat it.

I honestly don't get who told you to just test your TSH without including FT3 and FT4 in the panel...
Tsh, FT3, and FT4 are basically the holy trinity of thyroid labs; you've always got to order them together, at least according to the specialists I see at the Mayo Clinic.

Scott Allen10 said:I honestly don't get why anyone would tell you to just check your TSH without also ordering FT3 and FT4. It makes zero sense. TSH, FT3, and FT4 are basically the holy trinity here—you always test them together. At least that's how my endocrinologists handle it.

Just speaking from what I've seen in San Francisco... they usually just run the TSH. If that comes back out of range, then they'll bother with the T3 and T4. From a purely clinical or even a budget standpoint, I guess there's some logic to it. But for the patient? It’s just an extra trip to the lab if they end up needing those other tests anyway.

Yeah, that’s exactly what happened to me in San Francisco. Even though she clearly wrote down TSH, T3, and T4 on the referral, they only ran the test for TSH. So, I had to drag myself all the way back there just to get the T3 and T4 done.

Scott Allen10 said:I don't really get why someone would suggest testing just TSH without including FT3 and FT4. In my experience, TSH, FT3, and FT4 are like the holy trinity—you should always order them together. At least that's how my endocrinologists handle it...

Well, there you go. My doctor was actually checking my CBC😍 and iron levels since I mentioned feeling so exhausted, and she probably just threw TSH in there as a precaution. By the way, it turns out I am anemic, though I suppose that makes sense given how much my hormone levels are acting up lately.
I'm heading in tomorrow to have blood drawn for all three tests.

James Watson84 said:It’s almost certainly hypothyroidism. Cases where TSH levels spike autonomously, leading to secondary hyperthyroidism, are incredibly rare. While TSH can fluctuate due to other conditions, it's likely just a minor detail here. There's nothing to worry about.

So, what kind of treatment could they offer me for hypothyroidism?

neonheron12 said:So, yeah, Doc. She was checking my CBC😍 and iron levels since I've been feeling totally wiped out, plus she ran a TSH just to be safe. Turns out I'm also anemic, which makes sense given how much my hormones are acting like a moth in a bag of flour right now.
Heading in tomorrow to get blood drawn for all three tests.

Anemia often goes hand-in-hand with hypothyroidism. I'd suggest getting your cholesterol checked too.

James Watson84 said:It might be worth checking for anemia, as it often goes hand in hand with hypothyroidism. I'd also suggest getting your cholesterol levels checked, too.

Wildlands 🤮 🙂

neonheron12 said:So, what can they actually do for hypothyroidism?

Look, first thing's first: you need to get your T3 and T4 levels checked, then hit up an endocrinologist or a specialist for a thyroid ultrasound. They’ll likely run some blood work to look for specific antibodies to pin down the cause—usually it turns out to be Hashimoto. Based on those hormone levels, if you need it (and with a TSH over 20 and the symptoms you're describing, you probably will), they'll prescribe replacement therapy like levothyroxine. It usually takes a few months to dial in the perfect dose, but once that's set and you're doing regular checkups, life goes right back to normal.
There's a massive thread on thyroid issues further down in the 🙂 subforum, so it might be worth tossing your other questions and concerns over there.

EDIT: Let's wait until we see the actual T3 and T4 results. Until then, we're all just guessing. And seriously, don't sweat it 😉 😁 .

They might then look for specific antibodies in your blood to confirm the cause of hypothyroidism (which is most often Hashimoto). Depending on those hormone levels—and if your TSH is over 20 along with symptoms, which I suspect will be the case—they'll likely prescribe replacement therapy with levothyroxine. It might take a few months to fine-tune the dosage, but after that, with regular checkups, there shouldn't be any obstacles to a normal life.
There is a fairly detailed thread on thyroid issues further down in the 🙂 subforum, so it might be helpful to post any other questions or concerns there.

Thanks for explaining the procedure and protocol 🙏

Well, actually, maybe there is. Now that I'm reading this, people are talking about things like constipation and hair loss. If that happens to me, I might have a bit of a short fuse with those kinds of side effects; I'm not sure I'd handle it very well without feeling a little extra stressed out. Anyway.
If I don't usually have any symptoms (as far as I know, I don't), is it possible they could show up once I start the medication, or maybe some other nasty side effects?

neonheron12 said:Hey, if I’m not actually feeling anything right now (as far as I know, I'm fine), could symptoms pop up once I start medication, or am I looking at nasty side effects or something?

Hypothyroidism can be a slow burner. Your hormone levels fluctuate, and those early red flags—like feeling wiped out, lacking motivation, or just being "cranky"—often get blamed on something else entirely. You can even have subclinical hypothyroidism where you feel zero symptoms, or maybe just some minor stuff. Basically, your pituitary gland starts pumping out extra TSH to force a struggling thyroid to produce enough T4, just to keep your T3 and T4 levels in the normal range. It's actually a win if you catch it early before the heavy hitters kick in—things like feeling freezing all the time, constipation, dry skin, weight gain, muscle aches, or feeling depressed. Once you need treatment, the whole point is just to fix those low hormone levels and get them back into the healthy zone. It's mostly a game of fine-tuning to find that perfect dosage. Sure, there are side effects and precautions to keep in mind, but honestly, every medication has them—that doesn't mean everyone deals with them. Your doctor will walk you through all of that if it becomes necessary.

James Watson84 said:Hypothyroidism can develop quite gradually, and hormone levels tend to fluctuate. Early signs like fatigue, occasional lack of motivation, or feeling a bit "irritable" are often misattributed to other issues. It can also present as subclinical hypothyroidism, where symptoms are minimal or nonexistent—essentially, the pituitary gland pumps out extra TSH to nudge a struggling thyroid into producing enough T4 to keep T3 and T4 within a normal range. I suppose it’s a good thing to catch it early, before more obvious symptoms like feeling cold, constipation, dry skin, weight gain, muscle aches, or low mood set in. If treatment becomes necessary, the goal is basically just to correct those low hormone levels back to a normal range. The tricky part is just determining how long it takes to find that perfect dosage. There are side effects and precautions to consider, but then again, every medication has them, which doesn't mean everyone experiences them. Your doctor will likely walk you through all of that if it becomes necessary.

That leaves me with just two questions: on average, how long does it take to actually hit that "perfect" dose? And what are the chances my thyroid starts swelling into a goiter in the meantime, especially if this is subclinical? I noticed it mentioned that it can stem from things like iodine deficiency or similar issues, and I honestly can't put into words how much THAT scares me. It's almost as bad as public speaking or dealing with the DMV. 👎).

neonheron12 said:Then I've just got two more questions: on average, how long does it take to actually nail down that "perfect" dose? And what are the odds my neck starts swelling up in the meantime—especially since this is labeled as subclinical, which apparently happens because of iodine deficiency or whatever. (I can't even describe how much THAT scares me. It’s right up there with public speaking and dealing with the IRS. 👎).

1. There's no way to give you a straight answer. Every patient is their own unique case. It could take two months, or it could take six.
2. "Subclinical" just means you aren't feeling symptoms yet, or they're pretty minor. Basically, your TSH is high, but T3 and T4 are still in the normal range. It doesn't actually tell you *why* your thyroid is acting up. Most cases of hypothyroidism are actually caused by Hashimoto's, which isn't about iodine levels at all. It's a chronic inflammation triggered by an autoimmune response—basically your body attacking itself—often kicked off by something as simple as a common virus. In those cases, you don't deal with goiters. Especially once you start treatment. People living with Hashimoto's lead totally normal lives. Don't sweat it.

James Watson84 said:1. It’s impossible to give a definitive answer. Every patient is unique, so it might take two months or it might take six.
2. A "subclinical" diagnosis just means you aren't feeling much, if anything at all. Your TSH is elevated while T3 and T4 levels remain normal, but it doesn't explain why the hypothyroidism started. In most cases, the culprit is Hashimoto's thyroiditis, which isn't actually caused by an iodine deficiency. Instead, it's a chronic inflammation triggered by an autoimmune response—essentially the body attacking itself—often following a minor viral infection. That's usually why symptoms don't show up, especially once you start treatment. People living with Hashimoto's lead perfectly normal lives. I guess there really isn't any reason to worry.

🙏 I believe everything that's in bold, let alone what you're saying with that avatar. Thanks! 👍

I just got my latest lab results back, and it looks like my TSH has dropped significantly from 16.5 mIU/L down to 5.56. It’s still a bit high, I suppose, but I'm not really complaining 🙏 since my T3 and T4 levels are within the normal range and my iron levels look pretty steady.

However, my white blood cell counts seem to have shifted quite a bit—my neutrophils jumped from 53% to 75%, while my lymphocytes dropped from 35% to 18% and monocytes went from 8% to 3%.
Does anyone know what this might mean? I wonder if there's any connection here.
