I lost my thyroid to cancer. It was removed and I take 125

Customer Question

I lost my thyroid to cancer. It was removed and I take 125 mg of synthroid once a day. My TSH result was .074. What does this mean?

Your TSH is a pituitary hormone which regulates the thyroid ...

It gets high when your body is LACKING in enough thyroid hormone ( Synthroid is T4 = the thyroid hormone made by the thyroid is chemically identical...)

The TSH is checked to gauge your body response to the medication and normal range is 0.5 to 4.5...

To judge the appropriate dose it also is important to screen for symptoms ...

Too high of dose of SYNTHROID may cause you to have anxiety / insomnia/ high heart rate / weight loss/ diarrhea / heat intolerance

(Too low may cause dry skin/ hair loss / constipation/ fatigue / depression / cold intolerance )

Your low TSH suggests that your dose of Synthroid may be too high for you...this MIGHT be adjusted back down to 112 mcg / day and recheck TSH ( and discuss with you how you feel ) in about 2 months time ..
