My question is basic really. If you take too much thyroid medication, I expect the levels in your blood build up and get too high, causing symptoms of over production, such as rapid heart beat, loose bowels etc. So, once that happens, how long would it be before the thyroid hormone levels in your blood come back to a stage where you can get back to your normal dosage?
I take a natural thyroid replacement and with my doctor's blessing, attempted to raise the amount I take each day. It soon became obvious that I didn't need to raise my intake. Previously my TSH was 2.6 and after raising the level of natural thyroid my next result came back at 1.8, but my heart was racing at this level. However, I've cut back my dosage, missed days entirely, and eventually stopped taking it for a fortnight. Then I started with 15mg a day, and again my heart rate would increase. I've stopped taking it again for a few days and today started with 15mg again. I don't seem to have the racing heart this time.
Can it take a long time for an excess of thyroid hormones in the blood to reduce?
Sorry, this isn't as short and sweet as I first indicated, but I hope somebody can put me straight because somebody else told me that if my levels were too high, it wouldn't take this long for them to come down again, but I'm not too sure. Throughout Feb and March I tried to increase my dosage and only now seem to be able to start taking it again.
I am seeing my GP this week.
