Hypothyroidism tends to lower stomach acid, so vitamins and minerals are not absorbed as well. Vitamin D, B12 and ferritin are important to a hypothyroid patient. Vitamin D needs to be at least 50 ng/mL. B12 in the upper end of its range, and ferritin should be at least 100.
The beginning of my hypothyroid journey was so long ago that I don't think that my TSH was ever over the range. That is why I had so much trouble getting diagnosed for so long. I was never diagnosed with Hashi's, either, but I experienced the hyper period followed by full hypothyroidism, similar to Hashi's. So I really can't be sure of the cause.
Even though you mentioned that your TSH levels had been rising, they are still not high enough to get a doctor's attention, plus your TPO ab and TG ab tests were negative, so no evidence of primary hypothyroidism. This leaves central hypothyroidism, which is a dysfunction in the hypothalamus/pituitary system which results in TSH levels that inadequately stimulate the thyroid gland. Doctors like to think that central hypothyroidism is rare, but in reality it is only rarely diagnosed because of the fixation on TSH, or as some call it "The Immaculate TSH Belief". A good thyroid doctor will pay much more attention to signs/symptoms that occur more frequently with hypothyroidism, and also relative levels of FT4 and FT3, along with Vitamin D, B12 and ferritin.
By the way, sleep apnea can be one of the symptoms of hypothyroidism, so personally I would wait until you get your hypothyroidism diagnosed and adequately treated and then see if there is really a need for the sleep study.
I think it is gross negligence that the doctor has been so fixated on TSH, and ignored that your FT4 was below range, and FT3 being only 16 % of its range. So I will explain why I say that. If you don't want to get into this detail, then just skip over it; however, the more you know the better advocate you will be for yourself, to assure that you get the right diagnosis and treatment.
The basic problem is that most doctors just follow the AACE/ATA Guidelines for Hypothyroidism, that assume hypothyroidism is due to "inadequate thyroid hormone". Unfortunately that is only part of the picture. The correct definition of hypothyroidism is insufficient T3 effect in tissues throughout the body, due to inadequate supply of, or response to, thyroid hormone. " This definition takes into account that there are numerous processes and variables that affect Tissue T3 Effect. The level of Tissue T3 Effect determines whether you are hypothyroid, euthyroid, or hyperthyroid. Unfortunately again, the Guidelines only recognize a need to test for TSH (as a surrogate for FT4 level), and if above range, a confirmatory test for FT4. The upper range limit for TSH is set higher than would be expected, in order to avoid excessive false positive diagnoses. Instead it results in excessive false negatives diagnoses. If either test is in range then the diagnosis is that there is no thyroid issue.
This practice is totally inadequate. TSH is not an adequate surrogate test for FT4 since it has been shown to have only a weak correlation with FT4. Also, a confirmatory test for FT4 is also inadequate because only test results from patients with TSH levels above range are excluded. Thus the FT4 ranges established by each lab are not well standardized among different test machine manufacturers, generally validated, or based on large data bases of healthy adults with no thyroid pathology. Clinically hypothyroid patients with TSH within the reference range, people with hidden pathologies such as undiagnosed central hypothyroidism or autoimmune disease, and patients taking thyroid medication can all be included in the database. The range limits are then calculated to exclude only 2.5 % of test results at the low end of the range. So the probability of a confirmatory FT4 test actually being below the range limit is minimal.
When you look at the correct definition of hypothyroidism, TSH is inadequate as the primary diagnostic, since it has only a weak correlation with Free T4 and a negligible correlation with Tissue T3 Effect. Per the Guidelines, Free T3 is seldom tested based on the assumption that T4 always converts to T3 as needed, which has been conclusively shown to be wrong. The most important indicator, patient signs/symptoms, is most often totally ignored. And because of the additional processes/variables, serum FT4 and FT3 have only a weak correlation with Tissue T3 Effects.
So the most important thing for a hypothyroid patient is to find a good thyroid doctor that understands all this and is willing to treat a hypothyroid patient clinically, by testing and adjusting Free T4 and Free T3 as needed to relieve symptoms without being influenced by resultant TSH levels. Hopefully the new doctor you will be seeing understands all this and is willing to diagnose and treat clinically. I have some other info I want to get to you so I am sending a PM.

You are very welcome. Please let us know how things progress.
Yes, clearly hypothyroidism. Yes, I expect cortisol will not show as a problem. Low or high cortisol can have an additive adverse effect on thyroid issues, but are not the basic cause for your symptoms.
At least middle of the range. In the following link, check the list of 26 symptoms that are typical of hypothyroidism. You will find your symptoms there.

TSH rising last 5 years
JBoneske
I've posted a few weeks back about hypothyroidism. Havent seen endo yet but they are doing cortisol before appointment because they have my thyroid numbers.
below range free t4 at .6. . 7 is bottom of range. low 16% of free t3 range. so neither good.
anyway, I don't know much about this. my free T4 has been under range for at least 5 years.
looking at my TSH numbers they have gone from 1.72 to 3.02 in like 4 years. I've had terrible symptoms in the last year coincidentally as my TSH has risen.
Does this mean that I cant take low T4 levels anymore and my body is trying to make up for it by pushing more TSH?
_______________________________________________
A rising TSH can mean primary hypothyroidism (Hashimoto's Thyroiditis); however, your tests for TPO ab and TG ab were negative. Also, the increase in TSH is not all that large considering everything that can affect it. Far more important is that your FT4 and FT3 together were too low in the range and causing your hypo symptoms. Your D was low, but you have supplemented to optimize to at least 50 ng/mL. What about your B12 and ferritin? And we will find out about another important test soon: cortisol.
So the most important thing for you is to get a doctor to test and diagnose and treat clinically (for symptoms) by testing and adjusting FT4 and FT3 as needed to relieve symptoms, without being influenced by resultant TSH levels. Symptom relief should be all important, not just test results. Are you going to be seeing a good thyroid doctor soon?
Yes, you should be diagnosed as hypo now. I just sent you a PM with info. To access, just click on your name and then from your personal page click on messages.
Yes, with those symptoms and your low serum Free T4 and Free T3, it is hypothyroidism. Serum thyroid levels are not the only thing, however. Hypothyroidism is best defined as, "Inadequate T-3 effect in tissue throughout the body, due to inadequate supply of, or response to, thyroid hormones." If you look at Fig. 1 in the link I gave you above you can see the different processes and variables that create tissue T-3 effect. Serum thyroid levels may not accurately reflect tissue thyroid levels. Also, there are variables that affect the metabolism of thyroid hormone. Vitamin D, ferritin and cortisol are some of the more important ones that need to be optimized for you.
Also, there is information that agrees with your speculation about low testosterone being related to hypothyroidism.
The most important consideration for you, by far, is to find a good thyroid doctor. That does not necessarily mean an Endo. Many of them specialize in diabetes, not thyroid. Also most doctors have the "Immaculate TSH Belief" and only pay attention to that, which is wrong. If they test beyond TSH it is usually only Free T4 and then they use "Reference Range Endocrinology" by which they will tell you that a thyroid test result that falls anywhere within the range is adequate. That is also wrong, for a number of reasons. A good thyroid doctor will assess your family history, pay careful attention to your signs/symptoms, test your Free T4, Free T3, cortisol, Vitamin D, B12 and ferritin and make an integrated decision about treatment. If the Endo or your PCP are not willing to treat clinically, and prescribe T3 meds if needed, then you will need to look elsewhere for a good thyroid doctor.
If treatment is started, the med dosage will be continually increased until FT4 and FT3 levels rise enough to relieve symptoms. Depending on your starting dose, and the time interval the doctor uses for re-testing, this can take a while to get you to euthyroidism. If cortisol should show as a problem, that should be addressed even before starting on thyroid med. In addition to Vitamin D supplementation, if your B12 and ferritin are low, those must also be optimized. Recovery is not difficult if you have a good thyroid doctor.
If you are interested I have names of several doctors in the Madison/ Green Bay areas that have been recommended by other thyroid patients.
In the words of an excellent thyroid doctor, "The free T3 is not as helpful in untreated persons as the free T4 because in the light of a rather low FT4 the body will convert more T4 to T3 to maintain thyroid effect as well as is possible. So the person with a rather low FT4 and high-in-range FT3 may still be hypothyroid. However, if the FT4 is below 1.3 and the FT3 is also rather low, say below 3.4 (range 2 to 4.4 at LabCorp) then its likely that hypothyroidism is the cause of a person's symptoms."
Your Free T4 is actually below range, and your Free T3 is only at 16 % of its range, and your doctor is telling you he doesn't think it is thyroid related, probably just because your TSH is in range. Time to either get this doctor to a better understanding of how to diagnose and treat hypothyroidism, or find a good thyroid doctor. By that I mean a doctor that will treat clinically, by testing and adjusting Free T4 and free T3 as needed to relieve symptoms, without being influenced by resultant TSH results. Symptom relief should be all important, not just test results. Many of us have found that we needed FT4 at least mid-range, and Free T3 in the upper third of its range, and adjusted from there as needed to relieve symptoms.
You can confirm all this by reading the following link. I suggest reading at least the first two pages, and more, if you want to get into the discussion and scientific evidence for all that is recommended.

Also, you should be aware that hypothyroid patients are frequently deficient in Vitamin D, B12 and ferritin, so you need to get those tested and then supplement as needed to optimize. D should be at least 50 ng/mL, B12 in the upper end of its range, and ferritin should be at least 100. All 3 are important for a hypo patient.
You mentioned trt. If that means thyroid replacement therapy, what med and daily dosage?
