? Hashi Flair Up, What Do l Do?

I think I'm finally getting the hang of recognising a Hashi Flair. But what do l do medication wise? Do l stop for a few days? My TSH (and I'm using this as confirmation of the symptoms l have) has gone from 6 to 0.9 in three weeks. I have spent almost a year slowly increasing my NDT up to 2 grains which l have been stable and felt fairly okay on for the last 4 months.

My flair ups seem to be around this time of year and I've been unwell with a horrible virus and bad chest.

So in a nutshell, l don't know what to do 😢😢😭

Any advice would be great! xxx

You should continue taking your NDT daily. Have you had FT4 and FT3 tested? It is very unlikely you are over medicated with TSH 0.9.

Am interested in how you know when you are having a flare up?


I get fine tremours, very hungry every 1-2 hours, itchy skin and the trots. :0(

I don't know if this is a flair up or over medicated. Which I would be surprised at as I've titrated up so slowly on NDT for 8 months and tested regularly.


I thought with a hashimoto flare up that tsh would go up not down?

Are you gluten free? I found this was the most helpful step to take control of the Hashi's attacks?


Thanks all. I was a bit ill and actually forgot this post... (I'm so, so sorry)

I'm not gluten free. There are few joys in life but a bacon sandwich is on one them (I know, I know...).

I carried on with my usual dose (thanks Clutter) and feel terrible today so, handily had a BH kit and sent off a test this morning.

Also getting a cortisol test done via Genova.
