Lastest thyroid labs and some others, very ill

Hello Dr.

I am 31 years old and female. My latest labs for thyroid after being on Synthroid 137mcg for 2 years now (for hashimotos) are as follows:

TSH 0.25 ( 0.40-5.5)
Free T4 1.6 (0.8-1.8)
Free T3 302 (230-420)

ACTH 52 (5-27)
8am cortisol 27.7 (3.0-17.0)
DHEAS 679 (40-325)
Testosterone Total 51 (2-45)
Testosterone Free 13.8 (0.1-6.4)
IGF 127 (126-291)
Vitamin D, 25-OH Total 11(20-100)

I have been having horrible symptoms of weight gain, severe fatigue, acne, hair growth, muscle pain/aches, dizziness, headaches, etc.

What do you make of these labs, the endo is thinking cushings/pituitary problem. I had an MRI of the pituitary but it only revealed an empty sella.

Is my thyroid ok? Would I do better on a T3/T4 combo. The weight gain is horrible. I know you probably won't believe me but I am on a very strict carb controlled, low cal plan and in one day I can gain five pounds..but besides the weight I feel very ill.

I would love your input.

Thank you,

Marie

Thanks Dr. Lupo, you have been VERY helpful.

I am on weekly dose of prescription Vitamin D (50,000IU) and hopefully it will help, as I have osteopenia now at 31. I will look into the antibodies you said.

Yes, the cushings is so difficult to diagnose, as some tests have been high, some low.

Thank you again!

There is no data suggesting T4/T3 is better, but some paitents feel better with the combo.  The current thyroid labs are okay.

The high ACTH and cortisol need further evaluation -- ie, dexamethasone suppression test -- even with the empty sella on MRI.  These can both be elevated due to stress however -- the dex supp test helps sort this out.

The low Vit D needs to be addressed - check sprue antibodies (particularly with the history of hashi -- also autoimmune) and consider high dose weekly vitamin D treatment.  Make sure the calcium is okay as well -- probably already done.

The high DHEAS may be due to the high ACTH driving adrenal overproduction -- again, needs further eval as you have many symptoms suggestive of Cushings -- often a difficult thing to diagnose.
