I had my second child 10 months ago and my obstetric consultant said that my thyroid looked 'unusual' during pregnancy and to have it checked again following the birth.
I lost nearly all my pregnancy weight (about 2 stone) within 2 weeks of having my son and then around 6 months ago started to put it all back on. The weight gain has coincided with a combination of depression, antidepressants, tiredness, difficulty concentrating 'foggy brain' etc. so I arranged to have my tests redone as I thought I might be hypo.
Initially I just had my TSH done (Serum TSH level = 1.17 mIU/L) I was told that this result was normal, but I requested that my Free T4 and Free T3 be checked too.
I got the below results back today and my GP has said that my T3 is fine and the T4 is marginally below normal so he wants the tests repeated in 6 months time but said that there is no need for treatment at this time:
Serum TSH level = 1.08 mIU/L
Serum free triiodothyronine level = 4.5 pmol/L
Serum free T4 level = 11.2 pmol/L Abnormal ?Px. ?obese. ?euthyroid-sick. RSJ
I would say that both my T3 and T4 look on the low side?
Could anyone give me any advice, should I just go with the GP's recommendation or should I consider further investigation. Could I have a problem with my pituitary gland if my TSH is normal but my T4/T3 are low?
Any advice gratefully received. I really don't feel myself and really would like to get to the bottom of my symptoms.
PS: I have had a gastric bypass but all my other blood results including B12 have come back as normal.
