Okay, my wife was diagnosed with hypothyroid just over a year ago and she's been on medication for it ever since. They thought it might be Hashimoto's, but didn't diagnose that yet. 4 weeks ago she donated blood and immediately after didn't feel right. The next day she felt her heart beating in her ears, so hooked up our portable BP machine. She's extremely active and runs a BP of 120ish/70 with a resting HR in the 60's. The machine told her 90something over 50 something and a 130's HR. A quick google search said this can be normal while the body recovers from the loss of blood, but after 4 weeks it hadn't changed so she went to the doc today.
HR was 148 with a BP of 90/50 so they did an EKG, came back normal, and sent her for blood work. The call came at the end of the day and they said her thyroid is now hyper, not hypo, and they had a concern with her parathyroid and she needs to come back in the morning for more blood work. She's had extensive blood work in her thyroid treatment and high calcium in the blood has never been mentioned, so I'm not sure what the parathyroid problem could be.
My question is, how can that blood donation and subsequent BP and HR issue have done to change her thyroid condition? Is it possible that it's a complete coincidence?
