Have also submitted this in my palpitations post. Briefly, was diagnosed borderline thyroid in 2012/13. Took 50mg levo for a couple of weeks a couple of times then stopped due to palpitations. Tsh then seemed to normalize (maybe because I upped my low iron and b12 levels too). Now pregnant and tsh has jumped from 4.35 to 5.08 in 2 weeks. GP said 4.35 is 'normal' and that I didn't need to be tested. Tried 25,50 and 75, can't seem to get past 25 without palpitations, but think it's risking this pregnancy as fetal heartbeat has reduced in a week from 90 to 60. So I called my GP and left message to be referred to endo today. GP left me a voicemail today asking me to put in writing why I want an endo referral so she can understand and deal with my request. She said 'is it only for the thyroid'. Can someone pls give me some guidance on suggested wording to send to my GP for the endo referral. In lay terms, I feel that the GP has been rather unhelpful throughout, not realising the importance of the thyroid tests esp in pregnancy, I am the one that keeps having to push so how do I justify this referral to her pls?
