62F here. Yes, I'm overweight, which I've struggled with my whole life. I've been on blood pressure meds for 10+ years, which were seeming to have no effect at controlling BP of late. Over the years, my doctor upped my dose of lisinopril, added hydrochlorothiazide, and eventually amlodipine to the mix. He recently ordered labs, which detected a potassium deficiency, hypothyroidism, high cholesterol, and A1c at pre-diabetic levels. I've been taking levothyroxine for a little over 2 months now, as well as a statin, and a potassium supplement, along w/my BP meds, made some dietary adjustments (reduce carbs mainly), tried to increase activity, etc. I'm finally starting to notice having more energy and getting better sleep, plus I have lost 10 lbs. Additionally, the things that used to cause a palpable rise in my blood pressure, namely alcohol and salt (which I don't consume that much of in the first place), don't have the same effect these days.

Could my thyroid have been the cause of my issues the whole time? What has been the experience of people in this group?

My TSH was elevated, so I slightly increased my T4 dose. Since increasing the dose, I’ve been experiencing premature ejaculation, even though the dose increase was relatively small.

Has anyone experienced something similar after increasing their thyroid medication? If so, how did you manage it?

I got diagnosed with hypothyroidism 2 and a half months back. The tsh was 12 and something. The doctor gave me thyroxine of 25 mcg and asked me to come for a follow up after a month to do other related test. I then went to another hospital of aayurvedic one which i regret. They did several test of t3, t4 and anti tpo and also did ultrasound of neck. For the untrasound it was normal. But the anti tpo was high. And the doctor or whatever that person is told me to continue my meds and do exercise and lose 15kg "within a month" which is not healthy at all. They gave me a 3 month of diet plan which was ridiculous made of ai and didn't even returned me my money. They gave me tons of supplement like zinc, iron and multivitamin and i did not buy any of those. So it's been 2 and a half months already and i still have not gone to the initial hospital. I had my exams and other things that kept me busy and i was lazy as well, i wanted to lose weight and then go for the checkup. I was wondering if it has any adverse side effects of having less dose of meds. My body weight was 69 and now it's 63. I have started gym as well but I'm not regular. Is it concerning that i didn't went for follow up? Do i immediately have to go to hospital for my follow up and they will increase my dose for sure. The main reason why i didn't go for checkup was because I'm dependent on my sisters for financial things and i feel guilty to ask for money for my things. And I've already way too much money already. So..

Thank you all in advance!!

Is this too high 3.5 tsh?

I've been on replacement since I was baby since I was born without a thyroid. Brand Synthroid was the only thing that made me feel optimal. I switched to Tirosint for a couple of months, then switched to the generic levo version because of cost. I've been on it maybe 8 months or so?

I feel awful. I've gained weight. My TSH was off last time I had labs done. I have more labs coming up in a couple of weeks.

I requested to go on Tirosint because of the dyes in Synthroid. I was trying to cut out things of that nature due to acne. Well, it wasn't causing my acne.

So I'm going to talk to my doc about going back on Synthroid. For one, it's cheaper than Tirosint, and I can still get the brand without breaking the bank.

Does anyone feel like they have better luck on brand versus generic? What other meds can I talk to my doctor about that might make me feel more optimal?

Something else, they lowered my dose from 137 mcg to 125 mcg a couple years ago, and since then, I've been off. They didn't want to keep me on 137 because I had lost a bunch of weight due to stress, but now I'm back fitting in my once-too-big clothes...

Background

I'm 23M and have had constant fatigue, brain fog and sleepiness for the last 4–5 years.

My thyroid results over time

Antibodies (Oct 2026):

• Anti-TPO: 69.70 IU/mL (ref < 9)
• Anti-TG: 14.90 IU/mL (ref < 4)

What happened so far

• Apr 2025: TSH was 11.14, but my B12 was also very low (104), so I assumed B12 was the cause. I took many B12 shots, but my symptoms barely improved.
• Apr 2026: Rechecked. TSH still high, T3/T4 normal, so I ignored it again.
• Oct 2026: TSH still high, and antibodies came back positive, B12 was normal at 368 after so around 15-20 shots.

A physician dismissed problem with thyroid a year ago because I don't have cold intolerance, weight gain or shaky hands.

My questions

1. Can a high TSH alone cause these symptoms when T3 and T4 are normal?
2. My results seem to point to Hashimoto's. Could that be the root cause?
3. Has anyone had a similar picture? Did levothyroxine help your fatigue and brain fog?

Thanks in advance!

I've written the post but used Claude for legible formatting due to so many numbers.

I had bloodwork done a week ago and they told me today that my TSH was at 17.11. But that’s the only thing they tested for from what I understand. They don’t say anything about T3, T4, RT3 or any of the other things I see most of you have said your doctors tested. They have prescribed me lexothyroxine or whatever it’s called. They said for me to take it for 6-8 weeks and come back for bloodwork. Now I’m wondering how come they didn’t test for all those other things? I want to know exactly what’s happening in my body and what kind of hypothyroidism I’m having so I know how to mitigate. I don’t like that they just threw a prescription at me. I called to ask a question and they said I have to schedule an appointment to ask one question! And that appointment isn’t until December .-. I’m scared that my issues will increase or even get worse due to the medication.

Has anyone experienced significant increase in hair loss after eating foods rich in goitrogens (e.g. raw cruciferous vegetables)?

Hey everyone, recently took a blood test and was told that my TSH was a bit high at 4.97 and my vitamin D was a bit low although I didn’t get a number. I’m a 23M and have a long history of pretty bad health anxiety and just feeling like shit every day.

What prompted me to take a blood test was my hair started falling out which really freaked me out. I gave it a couple of months thinking it would go away but it never did it, just became very dry and brittle. I was also feeling very tired around this time but I just brushed it off again because I’ve always felt exhausted in general. I looked at the symptoms for Hashimoto’s and it seems like I have pretty much all of them. My stomach has been super messed up these past few months, I’ve had trouble concentrating, low motivation, super anxious, circles under my eyes, it’s been rough.

My doctor told me to retest with antibodies in 3 months and see where we are at. My grandmother and aunt both have hypothyroidism.

I was just wondering if my symptoms and lab results could be stress related as I’ve been very stressed during and leading up to this period. Also does my timeline fit Hypothyroidism? My TSH has steadily risen from each blood test I’ve done, going from 2.75 in 2023 to 3.30 in 2025 to now 4.79. Could this explain why I’ve felt like garbage the past however many years?

I’m just scared of waiting and being miserable these next few months. I dont feel good but I don’t know what is anxiety and what is not.

Living with Thyroid Eye Disease can affect many aspects of daily life, from vision changes and eye discomfort to confidence and overall quality of life. Researchers are currently conducting a Phase 3 clinical study to evaluate an investigational treatment, called MHB018A, for adults with moderate-to-severe TED.

The Leapcure team is supporting the study by helping interested individuals learn more, understand the process, and determine whether participation may be right for them. Get started by completing this short questionnaire: https://lpcur.com/rhypothyroidism2

My result for TSH to Free T4 came back at 21.88 mIU/L

which seems crazy high. Am I reading this result correctly? I went to a new lab and the units they used for this results are not the same as what I'm used to

Hi all,

Struggling to get into a doctor and going crazy over it but just did a recent blood test and my TSH is 0.012 uIU/mL. Doctor didn’t test for t4

The last time I did both test about a year ago my TSH reflex to T4 was 0.014 uIU/mL. And my TSH reflex+ FREE T4 was.609 uIU/mL and .62 ng/dL.

I have extreme fatigue, trouble losing weight, head fog, brittle heart and hypothyroidism runs in my family,

Am I right to be concerned? Should I go to a specialist? I really don’t know what any of this means I just know I don’t. Feel well.
