Do i have Painless Subacute Thyroiditis

[SAM_2022]

I have lost 16 Kgs in less than 100 days. I have GI issues - Post Parandial bowel movement (3-4 days every day), burning in upper abdomen, dull/gnawing pain in left of abdomen every day. I was diagnosed to have IBS - D. I also have sinus tachycardia. I am of late sweating in forehead. I am also having severe anxiety.

My thyroid profile readings from November are: TT4 - 81 nmol/L; TSH - 1.09 mIU/L; Free Thyroxine - 15.9 pmol/L; Free T3 - 4.6 pmol/L; Thyroglobulin Antibody 12.9 IU/mL; Thyroid Peroxidase antibodies - <9 IU/ML;

at end of December the marker values are: TT4 - 91 nmol/L; TSH - 2.11 mIU/L; T3 - 94 ng/dl.

I am being treated for IBS. but given my weight loss, tachycardia (along with orthostatic hypotension/tachycardia symptoms), i want to rule out Painless Subacute Thyroiditis. Do you think, with these values, i should get serum values for Thyroglobulin, TSHR-ab given TSH, T3, T4, TPO-ab, Tg-ab don't seem to suggest Graves and Painful SAT. BTW, i don't have pain or lump in the neck.

Ask for an early morning cortisol test as well. Your abdominal issues are very similar to mine prior to my diagnosis of Adrenal Insufficiency/Addisons disease.

Also request coeliac blood test

Testing vitamin D, folate, ferritin and B12 levels too
