Hello

[AgataMaria15]

Please help to interpret the results .I feel cold, feel chills in my whole body, I have a quick heartbeat, I'm tired all the time Ft4 level 26 (11-22), Tsh 2.21 (0.35-5) and Ft3 level 4.6 (3.9-6.8) I take carbimazole 10 mg daily, Ferrous 322 mg, Cyanocobalamin 50 mg and propranolol 3 x 20 mg.

Welcome to the forum, AgataMaria15.

How long have you been taking Carbimazole?

Your results are rather odd. It's unusual to have TSH >2.0 when FT4 is over range.

[AgataMaria15 in reply to Clutter]

I have been taking carbimazole for 6 weeks.For the first 5 weeks I took 5 mg,but from last friday I take 10 mg becouse my ft4 level ist high

AgataMaria15,

What was FT4 and TSH when you were first diagnosed?

[AgataMaria15 in reply to Clutter]

Ft4 was 24,7 and tsh 1.38

[Clutter in reply to AgataMaria15]

AgataMaria15,

I don't think many doctors would diagnose hyperthyroidism with FT4 24.7 which was mildly over range and TSH 1.38 is nowhere near suppressed. It is odd though that FT4 has risen on 5mg Carbimazole.

Ask your GP or endo to check thyroid antibodies. Positive thyroid peroxidase antibodies (Hashimoto's) can cause transient hyperthyroidism but it is usually self resolving within 3-4 months and its only when FT4 or FT3 are very elevated and TSH suppressed that Carbimazole is usually required.

I had made thyroid antibodies

Tsh receptor antibody level (RM) <1.0 negative

Thyroid peroxidase antibody lev <33 (0-59) negative

AgataMaria15,

TSH Receptor antibody is negative for Graves which causes autoimmune hyperthyroidism.

Thyroid peroxidase (TPOab) antibodies are negative for autoimmune hypothyroidism (Hashimoto's). However, some people are negative for TPOab but positive for thyroglobulin antibodies so Hashimoto's can't be conclusively ruled out. Indeed, some people are sero negative but an ultrasound scan will show they do have Hashimoto's.

As I said earlier, Hashimoto's can cause transient hyperthyroidism but it is unusual to have high FT4 with normal TSH and very unusual for FT4 to rise on 5mg Carbimazole although the rise in TSH is expected.

I can only suggest you have thyroid blood tests every 4 weeks to check your levels until it becomes clear whether you are actually hyperthyroid or experiencing a Hashimoto's flare.

Thank you.

I should continue to take carbimazole?

[Clutter in reply to AgataMaria15]

AgataMaria15,

I think you probably should because FT4 needs to stop rising.

[AgataMaria15 in reply to Clutter]

Hi Tsh 4.08 (0.35-5)

Ft4 12.2 (11-23)

the doctor says that it's great But my sister feeling very bad

How you think?

[Clutter in reply to AgataMaria15]

AgataMaria15,

These results indicate your sister is overmedicated. TSH should probably be between 1-2. FT4 has now dropped very low in range. Your sister's GP should reduce her Carbimazole dose.
