Monitored Vitamin D Therapy Safe for Patients With High Blood Calcium Levels, Case Western Reserve University Study  
6/27/2012 7:24:45 AM

Patients with a gland disorder that causes excessive calcium in their blood who also have vitamin D deficiency can safely receive vitamin D treatment without it raising their calcium levels, a new study has determined. The results with one-year follow-up will be presented Tuesday at The Endocrine Society's 94th Annual Meeting in Houston. Doctors often fear that raising vitamin D levels will further raise calcium blood levels in patients with primary hyperparathyroidism -- in which glands in the neck produce too much of the parathyroid hormone, which controls calcium levels. Yet without enough vitamin D, people are at increased risk of osteoporosis and broken bones. Vitamin D helps the body absorb calcium and is vital for bone health.
