last Sept I went to my gyno and my TSH was 2.9
I just had my regular physical (for cholesterol, etc...) and my TSH is 1.6
is that rapid a drop - by half in 10 months - normal?
I just turned 33 in May
The normal range for TSH is between 0.3 and 3. From what you say I'd guess you have a perfectly well functioning thyroid! TSH is important because if you go over the 3 level, that means your pituitary gland has to work extra hard to make your thyroid produce enough T3 and T4, which indicates your thyroid is getting sluggish. I had a TSH level of 16.9 when they started me on hormone replacement therapy. Levels vary according to your level of stress, work, physical exercise, time of the day and even the season, because it varies with your energy requirements. So a change between 2.9 and 1.6 is not a drop. It just shows you had different energy needs when you took those tests... Just aim at remaining within the normal bracket and you'll be fine!
Hope this helped. Have a nice day.
P.S: TSH means Thyroid Stimulating Hormone, and it's produced by the pituitary gland, at the base of your brain.
I'll echo schaufel. You sound perfectly normal. I'm fairly newly diagnosed hypo and we're still trying to get my dose right. My TSH levels in March were 10.9, and after 6wks on meds dropped to 0.02! Thats a big drop! LOL! I'm on a different dose now to get them back up into the 'normal' range.
I agree with the others. Your TSH can fluctuate from day to day. This is normal. If it continued to drop and you became HYPERthyroid, you would have symptoms like weight LOSS, alopecia, palpitations, heat intolerance...just to name a few. Hope this helps!
