Why are my FSH, LH and TSH testing results varying substantially within solely 3 weeks?
Sex: M
Age: 41
I've been on Synthroid (150 MGC/day) for the past few years because of Hashimoto's Thyroiditis. A few weeks ago I went to a topical endocrinologist for a checkup (it had been a while). My bloodtests showed
-low FSH (1.4) and LH (0.7)
-Thryoid Peroxidase antibodies (528)
-thyroglobulin antibodies (63)
-normal T3/T4
-normal TSH (0.68)
Three weeks later he run more blood tests which show:
FSH (1.5)
LH (1.6)
Prolactin (4.4)
TSH (0.16)
Growth Hormone, IGF, Testosterone (all are still pending)
My TSH went from normal (.68) to low (.16) near no change in medication. Also, my LH went from low to ordinary.
He sent me for a thyroid ultrasound which showed "heterogeneous hypervascularity" but no nodules.
Does anyone know if this might be caused by pituitary problems? My vision has degraded not long (have an apointment with the eye doctor for July 6).
Is there anything else this could be? Silent thyroiditis? Should I get an MRI? Is it conventional to have big swings in these hormones without varying medications?
Answers:
My bet is he will order MRIs of your brain; one with contrast, and one in need.
I suspect he's considering a pituitary tumor as part of the differential diagnosis. If one exists, it's treatable with surgery.
Don't panic.
Keep surrounded by mind that this is not the only possibility.
