Hypercalemia with Normal TSH - followup
by Hypo-guy, Mar 11, 2007 12:00AM
I am posting this note in response to a prior posting by Tarrigo on 11/15/2006
Which read: "I am a 25 year old male who was suffering from muscle twitching, anxiety and perceived muscle weakness. I had a neurological exam ....My calcium is slightly elevated and so is my red blood cell count. Any ideas as to what the root cause of my elevated calcium and red cell count might be?"
I am a 33 year old male that takes 150 mcg of Synthroid for hypothyroidism. My TSH levels have stabilized at around 1 after increasing dosages from 75 mcg over the last 4 years.
I have also experienced muscle twitching (Especially on the left side of my face and bicep muscles), muscle weekness and lack or energy/focus. I am a non-smoker, that drinks 4 cups of coffee a day. I am not obese. My endocrinologist noticed that I have elevated hemoglobin levels along with elevated calcium levels from blood analysis. This was confirmed with two blood tests. She had me stop taking vitamin supliments containing calcium/Vitamin D and performed a urinalysis, from which the results came back within the normal limits. She the recommended I have my parathyroid function checked using a "nuclear medicine scanning technique" . She has not mentioned any PTH abnormalities, but I do not believe that the PTH level was screened.
Should I have this "scan" done?
Thanks

You don't need a scan until the PTH and/or calcium is documented to be high. Then, the more important part is finding the right parathyroid surgeon as scans can be very misleading. Check out parathyroid.com for more info about this -- the site is by the most active parathyroid surgeon around -- very informative. There may be a good parathyroid surgeon in your area as well. BUT FIRST -- CHECK THE LABS>
