Hello Guys Im A 56 Years Old Woman. I Just

Hello guys Im a 56 years old woman. I just want to ask about the hyperparathyroidism regarding my case.

So long story short, I went to the doctor and had a check up, since my bones feels brittle and I feel quite irritated easily. So after the bloodtest shows up, the result was my calcium and pth level being high, so the doctor suggested me to have an mri and a scan in my parathyroid glands and they didnt see any tumors or anything, they said that it was fine, which is why they're wondering what is causing the rise of my pth and calcium level, they later assumed and told me that it was a hyperparathyroidism, so they told me to have another scan or which include radiation which I forgot what its called, but still the results stays the same.

So guys, I've been wondering what was the cause if my parathyroid glands are fine, because they told me that pth is being produced within the parathyroid glands, but the parathyroid glands has no tumor and etc. So please any doctors or etc that could explain and tell me what caused it or what is it.

Thank You :)
