Hi! Yes, a few mums I know have dealt with this, high calcium from a parathyroid issue is actually quite manageable once you figure out what's going on. From what they've shared, most doctors start with blood tests to confirm the calcium levels and check your parathyroid hormone (PTH), sometimes followed by imaging to locate the gland. If it turns out to be overactive, surgery to remove it is usually the route they recommend, and apparently it does sort out the calcium levels pretty well and stops complications down the road. In the meantime, staying hydrated and watching your calcium intake can help too. But definitely get your own specialist to run the full workup and chat through what's best for your situation, parathyroid stuff can vary quite a bit from person to person.
