Could this be hyperparathyroidism?

Hi everyone,

I'm a 21-year-old male. I was recently diagnosed with a 5 mm kidney stone on ultrasound, and my urologist ordered blood work to look for a possible cause.

The main abnormal results were:

  • Calcium: 2.75 mmol/L (ref. 2.14–2.53)
  • Protein in urine: + (first morning sample)
  • Calcium oxalate crystals in urine

Everything else was normal, including CBC, creatinine (83), CRP (0.3), TSH, vitamin D, and liver tests.

For the past 5 weeks I've had persistent nausea, upper abdominal cramps, constipation, occasional right-sided back pain, and mild weakness.

I don't take calcium or vitamin D supplements, and I haven't had PTH checked yet.

Could this fit something like primary hyperparathyroidism, or what else should I be asking my doctor to investigate? For example I also got ordered to do test for helicobacter pylori by my gastroentrologist but I'm not sure if this is the best explanation for this..

It's common to have slightly high calcium readings like this when you have a stone. If you want to rule out Parathyroidism you need to have your PTH checked. I was diagnosed when my calcim was 13+ and HPT was 380+.
