working 60 hours a week on 200 mg of levothyroxine

hello, i am new on here .... i have had an under active thyroid for 11 years now and my old doctor told me he had tried me on all combinations of medication to treat my condition , i started off on 25 mg but it kept going up by 25 mg each time until i have now reached 200 mg... the problem i am having is that my symptoms never seem to go away , my body aches from head to toe , my muscles constantly hurt and get cramps , i get sick a lot my joints hurt i suffer head aches on a daily bases i am always tired ... worst of all no one seems to understand !!! my home has become a real mess where i now live alone and its driving me crazy ( my mood swings don't help neither ) ... i have seen on here that a few people have managed to get it under control and feel back to normal .... my new doctor tells me i have to cut down working to at least 30 hours but i really can not afford to do this ..... so please can some one help me !!!!

If you post your recent thyroid results and ranges (figures in brackets after results) we can determine whether you are optimally medicated. Please also post results and ranges for ferritin, vitamin D, B12 and folate if they've been tested.

60 hours a week is very full on. Perhaps you could consider reducing your hours so you don't feel so exhausted and stressed.

trying to work 60 hours a week with hypothyroid is madness

however it sounds very likely that your not actually able to even utilise the levothyroxine and convert it into the t3 that every cell in your body needs to function

its vital that




vit d3 are checked because they must all be halfway in their ranges for the conversion process to work


thank you for your replies ... a few years ago i did have low vit d and b12 ... but my doctor told me i was unable to take supplements due to it interfering with my levothyroxine

It's fine to supplement as long as vitD is taken 4 hours away from Levothyroxine and B12 2 hours away. As it was a few years ago you should ask your GP to retest.


Vitamin D, B12, folate and / or ferritin all need to be at GOOD levels for thyroid hormones to work.

You will see, time and time again on here lots of information and advice about importance of good levels of B12, folate, ferritin and vitamin D, leaky gut and gluten connection to autoimmune Hashimoto's too

Stress is very bad for thyroid. Yoga, meditation, relaxing .......all would help.

Has your doctor tried you on T4 + T3? If not, then he hasn't tried you on any combinations at all. Just tinkered around with your dose - probably just looking at the TSH, which is a good way to keep patients sick!

This link explains how low vitamin D affects the stomachs ability to host good vitamin B - especially B5 / B6

So if you have low vitamin D, you will almost inevitably have low vitamin B of some sort. Since all B's need to work together, if one is low the others won't kick in well either

So along with the vitamin D we need a good vitamin B complex, plus probably extra sublingual B12 too

B5 / B6 are essential for good adrenal health and ability to cope with stress.

"Vitamin D deficiency leads to a change in the intestinal bacterial populations that make and supply us daily with 8 B vitamins. The B vitamins never came from the food, they have always been supplied in the daily doses we need by the bacteria we carried in our intestine. But the “healthy” bacteria need our vitamin D to thrive, when we don’t have enough we don’t pass down D to the bacteria and “unhealthy” bacteria who don’t make B vitamins replace our healthy bacteria. So vitamin D deficiency causes secondary B vitamin deficiencies"

Low vitamin D very strongly linked to all/most autoimmune diseases


thank you everyone for your advice , i have made an appointment with my doctor next week to get my blood checks done and will post them on here as you lot are amazing ... THANK YOU
