Low TSH with High T3

Given that Kaiser Dr's are slightly indifferent; I would like to inquire of the group if anyone knows what this might mean for me.

My blood work reports came back over the week end ( no, my Doctor has not contacted me - they just upload them online ) and my TSL level is so low it almost does not register; yet my T3 level is high.
Is this likely to indicate a thyroid problem that could has caused a 50 pound weight gain in 10 months, extreme hair loss, dry eyes, insomnia?
I am reluctant to contact my Dr for fear I will be dismissed; or thought to be imagining things. I am worn out, and really need to figure out what happened to me these past 10 months.

I just looked thyroid levels on WebMD. This is what was posted. Thyroid hormone tests Total thyroxine (T4): 11.8-22.6 micrograms per deciliter (mcg/dL) or 152-292 nanomoles per liter (nmol/L) in newborns up to 14 days old
6.4-13.3 mcg/dL (83-172 nmol/L) in babies and older children
5.4-11.5 mcg/dL (57-148 nmol/L) in adults
Free thyroxine (FT4): 0.7-2.0 ng/dL nanograms per deciliter (ng/dL) or 10-26 picomoles per liter (pmol/L)
Total triiodothyronine (T3): 32-250 ng/dL (0.49-3.85 nmol/L) in newborns up to 14 days old
82-245 ng/dL (1.3-3.8 nmol/L) in babies and older children
80-200 ng/dL (1.2-3.1 nmol/L) in adults
Free triiodothyronine (FT3): 260-480 pg/dL (4.0-7.4 pmol/L)
Free thyroxine index (FTI): 7.5-17.5 in newborns up to 7 days old
5.0-12.8 in babies and older children
4.2-13.0 in adults

Not sure if this helps at all, but may be helpful if you wanted to discuss with your doctor. My thought is that you do have a thyroid problem. I woud check out some of the articles on Webmd. I just typed in TSH. Information is always helpful when talking with your doctor. This way they know what you are talking about, and have done some research. Good luck.

This is what I found for TSH levels through webmd

Thyroid-stimulating hormone (TSH) Adults: 0.4-4.5 mIU/L or 0.4-4.5 mU/L (SI units)
Babies: 3-18 mIU/L or 3-18 mU/L (SI units)

High valuesHigh TSH levels may be caused by:
  • An underactive thyroid (hypothyroidism ). Hashimoto's thyroiditis is the most common cause of primary hypothyroidism.
  • A pituitary gland tumor that is making too much TSH. This is uncommon.
  • Not taking enough thyroid hormone medicine for treatment of an underactive thyroid gland.
Low valuesLow TSH levels may be caused by:
  • An overactive thyroid gland (hyperthyroidism ). Causes of hyperthyroidism include Graves' disease , a type of goiter (toxic multinodular goiter), or a noncancerous (benign) tumor called a toxic nodule.
  • Damage to the pituitary gland that prevents it from making TSH (a condition called secondary hypothyroidism).
  • Taking too much thyroid medicine for treatment of an underactive thyroid gland.
  • Pregnancy during the first trimester .
Hope this also helps out
