What Does This Thyroid Test Result Indicate?

Need dose reduction
Detailed Answer:
Good day,
Noted your concern.
The last TSH was 0.11 while on 120 mg Armour thyroid. That means that you are over replaced and dose need to be reduced.
By looking at your blood profile pattern from 2010 onwrds, i can see that your blood works looks good ( especially most of 2012) while on 50 mcg Synthroid. ( but i understand that you were not feeling well). I have a suspicion that you are being treated by a non endocrinologist now.
Most endocrinologists do not prefer Armour Thyroid as it is a crude animal preperation and diffcult to titrate. Occasional patient may not feel well while just being on Synthroid (t4) and we may have to add little bit of Cytomel ( t3). But this practice is discouraged by endocrinologists including myself. Our aim would be to keep your TSH between 1 to 3 while on Synthroid.
May i know what symptoms did you have while on Synthroid? And what was the TSH at that time?
This would throw some light and i may be able to help you further.
However, just based on your latest blood works, i can surely say that we need to reduce the current dose of Armour Thyroid,
Regards
Binu


Armour has both T4 and T3
Detailed Answer:
You must understand the difference between Cytomel and Synthroid. We do have 2 thyroid hormones, T4 and T3. Cytomel contains only T3 where as Synthroid has only T4. T3 is the active hormone and T4 will have to be converted to T3 for it's actions.
Some people will have diffiulty converting T4 to T3 and hence they continue to experience symptoms despite being a normal T4. In those patients, we may need to add Cytomel to Synthroid.
Armour thyroid has both T3 and T4 in it. You may have a defect in converting T4 to T3. It must be the reason that you are feeling better on Armour ( combination of T4 and T3).
However, the TSH shows that you are overreplaced and hence it is not good for your heart and bones. You need to reduce Armour dose a bit. I must confess that most endocriologsts will not have experience adjusting the dose of Aromour thyroid, simply because they dont use it.
