In brief: Probably none.
Most cases of hypothyroidism are picked up by routine blood testing, in which thyroid hormones (t3 (liothyronine) and t4) start dropping, and thryroid stimulating hormone (TSH) start rising from a little gland in the head (the pituitary or master gland).
Glands function on a feedback mechanism. If you have symptoms (lethargy, wt gain, dry skin/hair, constipation + 50 others), the DX is late.
