I've been diagnosed with under active thyroid for some time now.My thyroid tablets have been steadily increasing over the years. I'm in a job that deals with a lot of heavy lifting almost all day .This summer has been great and sweaty but drink plenty and your ok.As we are now leading into winter something funny is happening I'm actually overheating and stripping back down to my t-shirt when it's not so hot out
Surely this can not be good my diet is good and balanced I don't have to much caffeine. I also eat at right times so can eny body help with this one .I'm just getting into my late 40s I'm also male it would be good to shed some light on this .

It could be the menopause that’s kicking in with hot flashes. They generally are in the upper chest and arms and radiate out. It could also be of course over medication so yes get those bloods done. Do you have any other symptoms like feeling jittery?
Welcome to our forum. On your Profile it would be helpful if you gave a short history of your journey, i.e. when diagnosed, with what etc.
When you have blood tests for thyroid hormones, it should always be at the very earliest possible, fasting and a 24 hour gap from your last dose of levo and the test and take afterwards.
Levo is usually taken first thing when we get up with one full glass of water and wait an hour before eating. Food and coffee can interfere with the uptake of the hormones.
Levothyroxine is T4. T4 is an inactive hormone and has to convert to T3. T3 (liothyronine) is the only Active Thyroid Hormone which provides our energy and our millions of T3 receptor cells need T3. Many people convert levo into T3 without much bother but others may need some T3 added. If you're in the UK it is impossible to get it prescribed at present. Sometimes a rise in dose will do the trick but not always.
Some prefer a bedtime dose,in that case you miss this dose before a blood test and take after test and night dose as usual.
If you get a new blood test follow the above advice, and at the same time ask for B12, Vit D, iron, ferritin and folate and thyroid antibodies. If GP or lab wont do all of these, we have three private labs that do home pin-prick tests.
Always get a print-out of your results with the ranges. Ranges are important as labs differ and it makes it easier to respond.
I always felt too hot, even in cold weather and no thyroid. Dr P looked at my average body temps 35 so almost hypothermic, he said as my core temp so low, everything external would seem warm, made a sort of sense to me, so start taking body temp when you wake, hour after meds and 2 more, do it for a week and see what results are. Also if your average temps vary by more than (i think its 0.3) then it points to adrenal. My temp also drops after exercise which is classic adrenal, apparently. With thyroid most things are a process of elimination. x
Do you have recent FT-3 and FT-4 and TSH lab results ? You might need some tweaking . Sweating can possibly be a hyper symptom . When I sweat more I know my T-4 needs to be a bit lowered . Headaches is another symptom for me as is aches and pain especially shoulder neck and back .Palpitation Insomnia weight skin issues are symptoms for me too . I would suggest you journal your symptoms . Familiarize yourself with your symptoms corresponding to hypo/hyper symptoms . Low energy for me signals that my T-3 might be low .
Nutrients are very important for us . It helps our thyroid meds work better for us .
