No tsh. T3 through the roof

Low TSH indicates that your body is producing enough T4 - which is what your thyroid gland publishes. Your body converts T4 to T3 - which is the form of thyroid your body uses. Sounds like that is working just fine. You need to see an endocrinologist to have them unpack your values and how best to treat any problems. Possibly talk with your PCP about getting a referral.

ssivitality, Bless you. Battling thyroid myself right now.

It sounds like you may have either sublinical hyperthyroidism or Hyperthroidism and if your TSI is elevated along with a really low TSH like you have, it could be Graves Disease.

I have Hashimoto's Thyroiditis (elevated antibodies), BUT, it has not gone into Hypothyroid Disease so medication is needed. I was diagnosed almost 2 years ago with Graves Disease (Hyperthryoidism) as well. This week I was told that I did NOT have Graves Disease....I was misdiagnosed almost 2 years ago. With that said, they say I have Subclinical Thyroid Disease. I am presently on Methimazole 5 mg and they are changing me to PTU. The Methimazole caused neuropathy symptoms and extreme itching.

Thyroid is very complicated. Please read Isabelle Wentz book on Thyroid Disease. She cured herself from Thyroid Disease with healthy eating and supplements. She is a Pharamacist. I personally could not go by her strict protocol.

To be honest, I believe the high protein, almost no carb diet, too low of fats, sea salt (which has no iodine in it which your thyroid needs) & hardly no complex or simple carbs threw me into Thyroid Disease. I lost a lot of weight fast on this plan back in 2016 and the end of the year I started having symptoms. I personally cannot recommend this type diet to anyone after my experience. We need healthy fats...we need iodine...we need a few simple carbs & we need complex carbs. I went to the Endocrinologist in 2017 explaining my symptoms and she ran all the tests and diagnosed me with Hashimotos.

One medication that they do not prescribe much any more is Naltrexone for Thyroid Disease. It can treat both hyper & hypo, but, you have to start low and build up. It is for inflammation in the body as well. I couldn't tolerate the Synthroid or the Armour. The Naltrexone gave me bad headaches. Since I only had the high antibodies, she said I really didn't need to be on anything. Hashimoto's can push you over into Hyperthyrodism. You can go back and forth between Hypo & Hyper. Both of these diseases can have the same symptoms.

I go every 3 months for bloodwork and I get an ultrasound of my Thyroid.

I wish you the best with this. It's not easy to get a balance on meds, but, once you do, you feel so much better.

Praying for you. New Year Blessings to you.

It sounds to me like you have either Hypothyroidism or Hyperthyroidism. You may also have Hashimoto’s. You can have Hashimoto’s Disease without Hypo or Hyperthyroidism. I have both Hashimoto’s and Hypothyroidism and also showed low TSH, but also very high TPO Antibodies, almost 600 which are suppose to be 0. I was very lethargic, had very low B/P and was breaking out in hives. Find a good Endocrinologist, which are hard to find, and have them do a complete Thyroid panel on you. I wish you well!

I have had hypothyroidism for ~25 years that is controlled with Synthroid. The high-low numbers may seem backward, but Thyroid Stimulating Hormone is an indicator of how well your pituitary gland is cranking out hormones telling your thyroid to stop slacking; a large TSH number means decreased thyroid function, and a smaller number means increased. A normal TSH range varies based on the research. One range is a TSH high of about 0.45 to a low of 4.12 mU/L , and optimal of 0.5 to 2.5. It also varies by age, gender, and by person. If my TSH is up to 0.2 then I start having hyperthyroid symptoms because my thyroid is too active (irregular heartbeat and jittery), while a low of 2.5 results in low energy and weight gain (hypothyroid). I do best with a TSH of ~1. A full thyroid blood panel is needed to see where one is on the thyroid function spectrum, and then some time to see what works for you. Rather vague, but some good links: https://www.thyroid.org/patient-thyroid-information/ct-for-patients/february-2024/vol-17-issue-2-p-5-6/

I HIGHLY recommend Modern Thyroid Clinic in Austin, TX. They are amazing! They run all the proper tests and know how to actually decipher them. They also prescribe multiple meds, not just Synthroid, unlike most Endocrinologists. I see Melody Volz there.

Would you know of a thyroid clinic like the Austin TX one that is in Phoenix AZ ?? I have no way to get to Austin but need a good thyroid doctor.

No, but they do phone and video visits!

There are thyroxin replacements like Synthroid (levothyroxine), liothyronine for T3, and/or Armour or other meds that are from desiccated thyroids from mostly pigs. Mine was likely caused by whiplash from a distracted driver 25 years ago, but also could be associated with my celiac. Whatever meds (natural or synthetic), best to take them a few hours away from eating (a lot of foods interact and interfere with absorption).

Celiac and Hashimoto's are usually found together. My daughter and I have both. Gluten is not good for Hashis anyway.
Some people do not convert T4 to T3 and therefore need both. Synthroid made me feel worse. Armour did not work either. I've been taking Tirosint (the purest form of T4) and generic T3 for several years now with great results. You definitely need proper labs drawn and a competent doctor to decipher them.

Always take your T4 an hour away from meals. I take mine first thing in the morning. I take my T3 split (2PM and 6PM)

I have idiopathic rather than Hashimoto's, so just Synthroid works for me. My doctors recommended a minimum of 2 hours away from meals because calcium, iron, and others suppress Synthroid and some other thyroid meds.
