The hypothyroidism is appropriately treated and independent from the calcium
Would test PTH and calcium to evaluate for parathyroid disease.
Hydrochlorothiazide may increase blood calcium slightly, but if that is the only cause the PTH should be in the low-mid normal range.
Update - saw endocrinologist and daughter is now being treated for graves. No uptake scan because the doc said that is the definitive diagnostic tool but only needed if rai is being considered and she doesn't do rai in young girls. Started propanolol and tapezole. Another episode of blinding headache and dizziness last night but were able to treat with tylenol and ibuprofen. It breaks my heart that she will have to deal with graves for possibly a lifetime. I know there are many worse things to get and I keep telling myself this is manageable and treatable and we'll al be fine.
2nd child saw endo. She does not feel there are thyroid issues. Her feeling is that there is something whonky with the adrenal gland. She has ordered the following tests:
glucose, HbA1C, TSH, Creatinine, sodium, potassium, cloride, VB12, Ferrutub, CBC, thyroid antibodies, am cortisol, ACTH, DHEAS, Free T3 , Free T4, prolactin, and a 24 hour unrine for free cortisol.
She was pretty vague in what she was looking for. Is the adrenal gland associated with the thyroid gland? Any idea what she might be looking for based on these tests? I will be so happy when we stop having to navigate the medical world. We've been lucky to have great people helping us.
