Information on the latest vitamin D news and research.

Find out more information on deficiency, supplementation, sun exposure, and how vitamin D relates to your health.

I'm a 58 yr-old overweight female. For the past several years I've had significant problems with back and leg pain and weakness, inability to sleep, and poor cognitive function. I've also shrunk 1-1/4" in the last couple of years. My calcium serum has been high the past 2 years (10.6 and 10.7) but my Dr. said it wasn't high enough to worry about. (My research indicates that current protocol is to follow up on all calcium levels above normal.) I did my own research and found a lot of my symptoms could be due to primary hyperparathyroidism. When i suggested she check my PTH levels she got very defensive and refused to do it. She did acknowledge my pain could be caused by more than just my weight and finally ordered more labs (but still not a PTH test). My Vit D level was 19.9. From info I found on your site, low Vit D can increase PTH and could cause secondary hyperparathyroidism. So with low Vit D, and high calcium how would i know if the cause of my symptoms are Vit D deficiency, primary hyperparathyroidism, or secondary hyperparathyroidism? And if primary hyperparathyroidism is the cause and would only be cured through surgery, would it hurt to take Vit D to bring my level up to normal or optimal? She did prescribe Vit D, but info i received from from a medical assistant indicates she's probably just going to diagnose me with fibromyalgia.

    Time for a new doctor!!!! A doctor really should check any levels that are too high or too low. If they check everything associated with that cause and find nothing, then they can say “it’s nothing to worry about”.
    At a level of 19.9 is this a measurement of ng/ml OR nmol/l? That makes a BIG difference on how I am looking at this. If you do not know then what country do you live in?
    What kind of Vitamin D was prescribed and how much???
    You really need for someone to do a PTH test to know if it is elevated. By any chance were Alkaline Phosphatase levels done? Were they high or low?
    As you go along keep in mind I am not a doctor or scientist!!!
    You can read this http://www.vitamindcouncil.org/q-a-forum/reply/19020/ that I posted for someone else. So yes without the PTH level it’s hard go forward.
    This was a study done that showed it was OK to supplement Vitamin D with people that had primary hyperparathyroidism http://www.ncbi.nlm.nih.gov/pubmed/24423366.
    So the symptoms you listed in the first couple of sentences could all be from the Vitamin D deficiency. They could also be from other things.(Are those the only symptoms you have???)
    If you take Vitamin D, even a tiny amount can do it, and you have true hypercalcemia, you will get the below symptoms:
    The symptoms of hypercalcemia include: feeling sick or being sick, poor appetite or loss of appetite, feeling very thirsty, passing urine often, constipation or diarrhea, abdominal pain, muscle weakness or pain, feeling confused, feeling tired and bone pain. (do you happen to take multi vitamin with D in it?)
    This is not to be confused with taking Vitamin D, having low magnesium levels and possible getting the following symptoms from low magnsium: • Irritability or anxiety, Nausea, Headaches, Insomnia, Fatigue, Muscle cramps/twitching, Weakness and constipation.
    Please do not accept a fibromyalgia diagnosis.
    Let me know if you have more questions!
