We see patients over 40 years old every day who have had blood calcium levels over This is not correct! Blood calcium levels of Enter your age and our calculator will give the upper limit of normal calcium for you. Your Age. Calcium levels above this should be considered too high for your age. This next graph goes one step further and shows very clearly that patients with hyperparathyroidism have high blood calcium, which is shown in blue.
Note that diagnosing a person with hyperparathyroidism who is 18 years old is very different from diagnosing a person who is 65 years old. A normal, healthy teenager will have blood calcium levels that are above A patient who is 60 years old, however, should have calcium levels "in the 9's".
A calcium level of Teenagers with hyperparathyroidism typically have blood calcium levels between For adults over 40 years old, however, frequent or persistent calcium levels above One point here Remember, people of any age above 10 can get a parathyroid tumor, but the peak incidence is between the ages of 50 and See our page on age for more about this.
Other pages of this website have different graphs that show average blood calcium and PTH for our last 20, patients, but here we can easily show that most parathyroid tumors increase the calcium in your blood only modestly which is shown by the purple area.
Thus, most adults with hyperparathyroidism have calcium levels "in the 10's". Remember, adults over 40 or so should have calcium levels "in the 9's".
Now you see the biggest challenge we face Every day we see patients with parathyroid tumors who have never had a calcium level that was "out of range" - because the range given was incorrect. In many areas of life, and many areas in medicine for that matter, a higher number is more significant than a lower number.
A cholesterol of is "worse" than a cholesterol of , for instance. Blood calcium levels are the big exception to this rule. This is why we do not recommend "watching" or "monitoring" your slightly high calcium to see if it goes any higher.
First, how high it is doesn't matter! A "slightly" high calcium for a number of years can cause severe health problems discussed in great detail elsewhere. Second, we know what happens when parathyroid disease goes untreated. The calcium level may never get into the "extremely high" range, but over time the risk of complications from the disease including osteoporosis, kidney stones, kidney disease, cardiac arrhythmias, chronic fatigue, memory loss, insomnia, and more rises.
How high the calcium has become is a very poor indicator of the severity of primary hyperparathyroidism. In summary, normal calcium levels vary with age. Your body wants to keep your calcium in a tight range, and the parathyroid glands are responsible for that. Treatment for hypoparathyroidism aims to relieve your symptoms and bring the levels of calcium and other minerals in your blood back to normal. The normal calcium range is around 2. You'll be advised to keep your calcium levels in a slightly lower range — for example, 1.
Your recommended range will depend on your circumstances. Calcium carbonate and vitamin D supplements — usually calcitriol Rocaltrol or alfacalcidol One-Alpha — can be taken to restore your blood calcium to these levels. They usually have to be taken for life. Here are 2. This simple, at-home test can introduce you to your metabolic hormones. Health Conditions Discover Plan Connect. Calcium Blood Test.
