Hyperparathyroidism while taking anastrozole or after stopping

martha323

Note: This is a question about the parathyroid glands, not the thyroid. The four parathyroid glands are very small (each one the size of a grain of rice) located behind the thyroid. They regulate the amount of calcium in the blood.

Has anyone been diagnosed with high parathyroid hormone while taking anastrozole (or another AI) or after having stopped? I was diagnosed with hyperparathyroidism last year and recently saw an endocrinologist. I have normal calcium and normal kidney function. I will be having an ultrasound and a nuclear scan in about ten days to see if there is a tumor on one of the glands or if the glands are enlarged.

Thank you and my best to all. This site was so helpful when I was in treatment eight years ago! I will be forever grateful for all of the support.

Martha, I don't have experience with taking an AI, but did have varying high parathyroid levels and calcium levels for years after BC surgery. I finally had an errant parathyroid adenoma removed over 2 years ago and have not had problem since. There are at least two threads which discuss parathyroids on BCO. Just type parathyroid is the search box. if you have specific questions, please don't hesitate to ask. I had had ultrasound and scan which was inconclusive until I went to doctor who specialized in parathyroid! All the best for your upcoming tests. Please keep us informed.
