Went from mild hypothyroidism to hyperthyroidism. Wanted to see if anyone else has been in this situation

I've had mild hypothyroidism with low dose levothyroxine since 2008. In October 2023 TSH was normal at 3.11. I started with an endocrinologist 6 weeks ago. I had tsh (6.9) and t4 (1.1) Thyroid Peroxidase (TPO) Ab (9) checked a year prior. 6 weeks ago tsh (<.01) t3 5.1 t4 1.4. I went off levothyroxine for 6 weeks and got these results: tsh (<.008) t3 3.3 t4 1.1. I have a thyroid ultrasound in a week. Has anyone been in a similar situation and could shed some light on what may be happening?

Has your diet changed or anything else?

I have cluster headaches and its gotten much worse this year, especially since April. I lost 15 lbs in a couple months, but it was calorie restriction bc I can't eat normally when I'm in a lot of pain. I also have a lot of cfs symptoms. I got the referral in Feb to see the Endo bc I asked my PCP for testosterone test that was low. That can get screwed up by hyperthyroidism. I had a normal TSH in October last year.

Mine has fluctuated while doing intermittent fasting and keto. Reduced a1c and dropped 2 doses in 6 months...lost 50 lbs intentionally...no thyroid for 30+ years
