It appears you likely have Hyperthyroidism from Graves disease. TRABs are typically positive in Graves disease.
Graves is known to undergo spontaneous remission over time. Based on the information you have provided it seems this is occurring with you now. This is a good sign. As long as the blood tests for thyroid such as TSH, free T4 , total T3 , Total t4 and T3 resin uptake are within normal limits, it is acceptable to stay off Thyrozol. However it is important to monitor it periodically to ensure there is no re-appearance of the condition, as can and doses happen sometimes.
So initially I recommend testing every 6 weeks (sooner if you experience symptoms suggestive of an overactive thyroid) and less frequently thereafter to ensure stable long term remission.

Regarding your intent to become pregnant, it is best you are under regular care of a reproductive endocrinologist, or if this specialty does not exist in your country , then see an endocrinologist as well as a obstetrician.
there are few important considerations here:
1 Methimazole is not recommended in the first 3 months of pregnancy. Instead, PTU (propyl thiouracil) is. I dont know exactly which one of these two thyrozol is. It could be carbimazole too but it clearly appears to be some type of thionamide which is a category of medications used worldwide for hyperthyroidism.

2 It is important your thyroid levels are normal before and during pregnancy, regardless of whether you are on medication or not

3 Even if your thyroid levels are normal, TRABs can potentially affect the baby. Therefore it is important to monitor the fetus. This can be done by specialized doctors only

I read your lab reports. Here are my responses:

1. By reading my report, are you more sure that mine could be Graves disease?

quite likely, although the best way to determine this is to perform a test called 'Radioactive iodine 123 uptake and scan'

2. Does Graves disease mean that it will turn to be hypothyroidism
sooner or later?

Not necessarily

3. I was told that high TRAB represents high rate of reoccurence. Is it true?

There is some data to suggest this may be true

4. Is there any medicine I should take to control Anti-TPO, Anti-TG and TRAB?

Sometimes steroids like prednisone are used to control the auto-immune response, in particular from the TRABs

5. When you say "It is important your thyroid levels are normal before and during pregnancy", do thyroid levels include Anti-TPO, Anti-TG and TRAB or just T3, T4 and TSH?


TSH, T3 and T4 definitely need to be normalized. The antibodies are more challenging to manage

6. Can hyperthyroidism case loss in bone density? I was confirmed to have hyperthyroidism last XXXXXXX and had been taking medicine until last month. I did a bone density check today and was told it's a little bit low although not too serious. What should I do other than taking calcium tablets?

Treating hyperthyroidism will stop the bone loss from the overactive thyroid hormones


7. I don't have pop eye but my neck gets a little bit bigger. Will the pop eye symptom develop later on? Can my neck go back to normal?

Eye disease in Grave's can follow an independent course. Follow the guidance of your endocrinologist
