Customer Question

Hi I have noticed that over the past several years I've had some high calcium levels, mid 10s. I also recently had an abnormal low vitamin D (25) which is weird because I'm always outside. However my pth level seems to be always within the range the lab gives.I have a lot of symptoms that would go with having a parathyroid tumor but I wanted to know if people can have this condition and have normal pth levels? Or should I forget this and look for something else for the cause of my symptoms?

People with parathyroid tumors with have calcium levels that are really high, usually 14+.

In addition, their parathyroid levels will be high, usually 5-10 times higher than normal.

Many many people have low Vit D levels from decrease absorption in the GI tract.

I would start taking over the counter Vit D and look else where for high levels of calcium.

However, this could just be normal for you - there is a disorder called familial hypercalcemia which is caused by decreased urine production of calcium.

I hope this helps!

What are the other things that can cause high calcium?
Expert:  Dr. Scott replied 1 month ago.

Hypercalcemia is a relatively common clinical problem.

Among all causes of hypercalcemia, primary hyperparathyroidism and malignancy are the most common, accounting for greater than 90 percent of cases.

It is usually not difficult to differentiate between them.

Malignancy is often evident clinically by the time it causes hypercalcemia, and patients with hypercalcemia of malignancy usually have higher calcium concentrations and are more symptomatic from hypercalcemia than individuals with primary hyperparathyroidism.

Other common causes are medications (such as tums or calcium supplements), thyroid disease, kidney disease, adrenal disease, and inherited causes.
