Hypothyroid can present with heart palpitations in some patients

severe vitamin and ferritin depletion occurs in the process of becoming hypothyroid

so you really need your ferritin and folate levels checked

vit b12

vit d3

should also be checked

because unless all are totally optimal recovery from hypothyroid is difficult

ferritin must be over 70 and if its not you will need to take iron plus at least 1000mg vit c 4 hours away from the levothyroxine

its also vital that you take a really good multi vitamin just before bed every night

whatever you do NEVER take your thyroid medication for 24 hours before a thyroid blood test or your doctor will try reducing your dose and you will be back to square one

Thanks I took my meds just before the blood test on Friday I didn't no not to I won't make that mistake again I think my iron levels were checked with my first blood test for anemia an all was ok but will ask for the others to be checked thanks for reply it's all very scarey for me because I haven't got a clue what's happening x


Welcome to the forum, Shaybenholly.

As RFU says, don't take your Levothyroxine until after your next blood test as it can skew the results. Ask for a printout of your results with the lab ref ranges (the figures in brackets after your results) after every blood test and you can post them in a new question for comment/advice.

25mcg is a very low dose so it probably won't affect your test and if your TSH is still elevated your GP will probably increase it to 50mcg.

Symptoms improving when you first have Levothyroxine and then resuming is a sign that you responded to the initial dose 25mcg but your body is telling you it needs more now.

Take your Levothyroxine with a full glass of water on an empty stomach one hour before, or two hours after. food and drink, two hours away from other medication and supplements and four hours away from vitamin D3, calcium, iron and oestrogen.

Ask your GP to test ferritin, vitamin D, B12 and folate as hypothyroid patients are often deficient/low and these deficiencies can cause musculoskeletal pain, fatigue and low mood similar to hypothyroid symptoms. Post your results with the lab ref ranges (the figures in brackets after your results) in a new question and members will advise whether supplementation is required.

These links explain more about hypothyroidism (no horror stories ;) )

best to go gluten free for now

plus never never believe any doctor who says in range or normal

always get a print out of the actual result inc reference ranges
