Any answers to this please?

I was hypothyroid for three years . Diagnosed Hashimoto. ( Tpo 180. )

December 2021 Hyperthyroidism diagnosed, Graves (TRab antibodies 4.6 ). Currently on Carbimazole.

So if this is what happens

You are hypothyroid, it's physically impossible for your thyroid to regenerate and you become hypERthyroid.

How has my thyroid started to produce hormones?

Have been curious about this and asked my Endo the question, he shrugged his shoulders 🤷‍♀️

It’s more unusual to go hypo then hyper but not unheard of. with autoimmune Hashis the immune system attacks and damages thyroid leading to the under active levels. With Graves the thyroid (or what’s left of thyroid) is being stimulated often very suddenly & unexpectedly.

In previous post you said FT4 elevated & FT3 double. I has similar levels gradually building from a toxic nodule. It is not unusual for Graves to reach 3x or 4x normal range. So your levels not reaching dangerously high levels may be partly because there’s less thyroid to produce hormone and it was picked up from monitoring.

Is carbimazole managing your levels? How much carbimazole are you taking. Have you had levels checked & carbimazole adjusted? This should be 6 weekly until stable.

As you have both hashis & graves you may have more unexpected fluctuations if this is difficult to manage you might have to look a block & replace method. Higher dose of carbimazole to block and replacement hormone to maintain levels. This is more stabilising option.

Hi PurpleNails, yes levels being managed with carb. (By my dosage though , endo thinks i’m on a higher dose. ) blood checked every few weeks. Suppose having experienced underactive, I have an advantage and absolutely will not allow the endos medicate me into hypo. I was just puzzled by my thyroid activity, but i guess mine hasn’t been destroyed by hashis. I am awaiting a scan on a nodule. Thank you for replying
