I'm sorry to hear about your mother, what was her thyroid diagnosis?
Is she on any medication for it?
When i had my thyroid removed last year I was given calcium supplements immediately afterward and they checked my calcium levels for the entire day after my surgery.
It's a Parathyroid disease issue with the calcium levels I think.
(But I'm merely a patient, not a doctor)
Has she been diagnosed with Diabetes too? The high potassium and calcium levels and renal disease are linked as well.
If her current doctor hasn't checked her for any of this and has
only recommended dietary restrictions on dairy

, it's time for a new doctor altogether I think.
Best of luck to you and your mother.
