Thank you to everyone who has provided advice so far, it's been really helpful and I am now supplementing iron & using a vitamin D spray to increase my levels. I went to see a private endocrinologist as advised by the NHS endo to request a private prescription for T3 which I now have.
I paid for the privilege of the consultation last night which was rather disappointing as the Consultant believes I was misdiagnosed, said I am not hypothyroid and asked if I would stop taking the medication for 2 weeks to get a clearer blood tests. He said my antibodies are showing in the normal range which is usual when over medicated for a long time (my gp over medicated me since I was diagnosed and I have not felt well since). He said its a shame an antibody test was not carried out when the diagnosis was made. I checked and there was an antibody test and I have included my original tests below. I was not on medication at the time for the January results or the March results. I did refuse to stop taking my medication but he has made me feel very uneasy about my diagnosis.
My blood tests back in January 2010 are as follows:
Free T4 level: 14.8 (range 10 - 22pmol/L)
TSH level: 4.76 (range 0.4 - 4mu/L)
Blood results in March 2010
Free T4 level: 12.2 (range 10-22pmo/L)
TSH level: 5.97 (range 0.4 - 4mu/L)
Thyroid peroxidase antibody level: 91 (>75 positive)
When my son was born at the end of 2008, I lost the baby weight and went back to 9 stone and I felt well. I went back to work full time, changed my job and in September 2009 I felt unwell. At first I put it down to working full time, a change of job and my hormones settling after having my son. My symptoms at the time was an increase in weight by 2 stone over a short time (never been over weight before), hair falling out and I had to lay it on the side of the bath when I had a shower, extreme fatigue, tearful, kept forgetting things, losing things and struggled to remember important things, difficulty in walking, lethargic and I was fainting.
Please can someone advise, am I hypothyroid?
The reason I ask I came out of the consultation feeling like I was imagining it all and I need to pull myself together. I wouldn't want to take medication if the diagnosis is incorrect but I believe the results above indicate an underactive thyroid.
