Wacky labs, weight gain, trip to the ER, help please

I don't understand what's going on with my thyroid. I've been on desiccated thyroid for about 6 yrs after years of the T4 meds. My last blood test showed the following:

TSH <.006 (.45-4.5)
Free T3 3.2 (2.0-4.4)
Free T4 1.17 (.82-1.77)

My morning underarm body temp in usually around 97.1.

I'm having trouble losing weight. So I upped my dose myself by a quarter pill and ended up in the ER with rapid heartbeat.


For what it's worth, my B12 is sky high at 1646 (211-946)
SHGB 142.7 (24.6-122)
Cortisol (a.m. blood test ) slightly elevated at 25.4 (6.2-19.4)
Vit D 47.9 (30-100)

I know the Free T3 and T4 should be higher but I've never had a TSH this low and I don't like the feeling of every time I eat my heart beats very strongly.

I seem to have symptoms of hyper and hypo and I don't know what's up.

Also I bought a glucometer and my numbers for glucose have been a bit high. Could that be related to this?

An input appreciated.

    First, have you been to your endocrinologist? Looks like your body is going through some adjustments.

    Your thyroid levels (T3 and T4) are in the normal range, according to the reference ranges you listed. My doctor has told me that the TSH (your body's Thyroid Stimulating Hormone) is the last number to following in line. The TSH should be the inverse of the T3 and T4 tests, meaning if the T3 and T4 is normal, or high, the TSH will be opposite, low. Your TSH is low, which means that your body thinks you have enough thyroid hormone. Your body doesn't need anymore thyroid hormone, so the TSH isn't there. That would explain why when you took additional medicine, it was too much for your body and you got the racing heartbeat.

    I'm not familiar with how glucose would affect your thyroid levels. An endocrinologist would be able to shed light on this as well.

    Yes he reduced my dose from 130 mg Nature-throid to 97.5. It is strange because if my TSH is that low I would think my Free T3 and T4 would be higher. He is puzzled to say the least.
