Can the intake of Synthroid cause hyperthyroidism and effect the eyesight?
Could you attach the report please
Noted yourconcern. If you have had a succesful thyroid ablation with radio iodine, there is no thyroid gland left. After the ablatio, you develop hypothyroidism as the gland is destroyed and can not produce anymore hormone. To treat hypothyroidism, you are given synthroid for life. If the dose of synthroid is in excess, it can cause hyperthyroidism. May i know your weght and height please?
What did your latest Thyroid blood work show? Could you attach the report if possible. The thyroid stimulating immunoglobulin can remain elevated for years even after radio iodine treatment and when you have no thyroid gland left, it can not harm you.

I have read a number of articles on this issue and understand that no one has come up with an effective non-harmful treatment for Graves. In some cases seleenium has been helpful to some extent. My concern is that no other thyroid medications have been tried eg Armour etc. to see if the TSImight be reduced. Also dietary etc. measures that might assist in the reduction of the TSI. Hyperthyroid is viewed as a cured disease and little attention seems to be paid to problematic cases. PCan you offer some suggestions that might be helpful as guidance in this matter? I started this upward move from125mcg because of chronic serious fatigue but the higher doses have not helped.
Selenium. Avoid smoking
Please do not bother about elevated thyroid stimulating immunoglobulin. In your case, it has not causes Grave's ophthalmopathy. So not to worry.
Your thyroid function tests are looking fantastic on current regimen of Synthroid.
So there is no need to change the current dose. You weigh around 66 kilos. So actual requirement is 112 mcg Synthroid a day. But for some reason, you are requiring a higher dose. As long as your TSH is staying in normal range, please stick to current dose . Please be aware that, synthroid dose/Armour will not influence the levels of TSI.
In some studies, Selenium in a dose of 200 mcg( microgram) a day was found to be helpful in reducing thyroid auto immunity. So there is no harm trying it. It may be of use to reduce TSI. Most endocrinologists use it in mild cases of Grave's ophthalmopathy. There is no great evidence though.
If you smoke or are exposed to cigarette smoke, please avoid it as it is known to worsen thyroid auto immunity. Eat a diet rich in iodine.
