TSH down to 0.25 from 49

Hi everyone.

Great news this week; my TSH is 0.25.

I feel better than I've felt in a long time with lots of energy and mental clarity. I have, however had lots of headaches and one debilitating migraine.

I've also recently switched to a high fat, low carbs diet including lots of coconut.

I thought the diet made me feel great but gave me headaches, I now wonder if it's the TSH level.

Is it likely the doctor will want to reduce my Levo? I don't really want to because I feel good finally! I'll take the migraine if I have to!

Has anyone got experience of this?

Hello there.

I'm no expert on thyroid issues, but regarding your new way of eating; how long have you been doing this, and is it very different from your previous diet?

The reason I ask is some people find it takes their body a little while to adjust and they find themselves suffering, for a short while, from what is know as "carb flu".

It could be worth consulting Dr Google on carb flu and see if that makes any sense? It's just something to consider,


Yes the new way of eating is very different. I'm off bread, pasta and potatoes and have a small amount of brown rice now and then. I haven't been at it long, perhaps three weeks but I fell off the wagon last Sunday and ate a proper Sunday dinner with yorkshires and roast potatoes, and a bottle of wine 🙈...then I rewarded my bad behaviour with a pasty as I drunkenly waited for the train home!

I think the headache could be comedown from my carb fest.

But I am still interested to know whether anyone has had similar readings and how their dose was altered. Im worried about dealing with my GP

I've had real problems with him belittling the condition. I asked to see an endo and he sniggered and told me he had literally hundreds of patients in my situation but that I could go and see one "about whatever it is; rhubarb allergy, that you think you've got" (I had mentioned reading about gluten being a factor in Hashi's.) It was so condescending really.


Copied and pasted "The Herxheimer Reaction is a short-term (from days to a few weeks) detoxification reaction in the body. As the body detoxifies, it is not uncommon to experience flu-like symptoms including headache, joint and muscle pain, body aches, sore throat, general malaise, sweating, chills, nausea or other symptoms."

How long have you been on the new diet?

Also, you may have an intolerance to coconut? or anything else you are eating more of than you did before.
