I have a calcium level of 10.7, 9.8, and 10.6. My PTH level was 26 six months ago when my calcium level was 10.7. My PTH is now 23. It is possible that I have hyperparathyroidism? My primary care doctor says it is normal, but Parathyroid.com from the Norman Parathyroid Center say that I do. I am trying to get to the bottom of why I feel so tired all the time. This has been going on for about two years now. I also have an irregular heartbeat and atrial fibrillation. I have memory loss and cannot concentrate like I used to. I have thinning of my hair, depression, acid reflux, etc. Thank you.
