Hypercalcemia is the medical discussion for "loftier blood calcium." It is almost never normal and near e'er requires further testing and oftentimes treatment of the underlying trouble to bring the high blood calcium back into the normal range. Hypercalcemia should not be ignored or just "monitored" because information technology typically means bad things are on the manner. Calcium is one of the most important minerals in your trunk that serves many functions and thus it needs to exist kept in a very tight range – you don't want too lilliputian OR too much of it. Considering a normal blood calcium is required for good wellness, the measurement of claret calcium levels is part of the standard blood tests when patients take an annual checkup, or become to the doctor (or emergency room) when feeling sick. When your doctor orders routine blood tests, calcium is usually function of the standard panel (information technology's in the Basic Metabolic Panel, one of the near mutual blood tests).

What Physicians Need to Know About Hypercalcemia

Many physicians end up on this folio afterward searching "hypercalcemia" online. The about important matter for doctors to know is that hypercalcemia is almost never acquired by cancer in the ambulatory patient. If yous take a patient in your part that isn't dying of cancer (that y'all take already known about for months or years), then the hypercalcemia is almost always due (over 99%) to primary hyperparathyroidism. Cancers exercise not present with loftier calcium--in fact, very few cancers are ever associated with high blood calcium, and when they are, the patient is already in the hospital (in the ICU?) and finish-of-life preparations have been ongoing for months. An ambulatory patient with hypercalcemia does Not need any form of cancer work upwards. They do not need a CT browse, MRI scan, PET browse or even a chest-x-ray to "rule out" cancer. About every patient in every doctors part (even an oncologist's office) with hypercalcemia should be presumed to have hyperparathyroidism and tests run to confirm this diagnosis outlined on our Parathyroid Advanced Diagnosis page. There is a lot of very valuable information for doctors and patients further down on this current page, and so keep reading.

Hypercalcemia vs. Normal Calcium Levels Will Modify According to your Age

Nearly labs volition give a normal calcium range from about 8.8 to 10.5 mg/dl. But this doesn't mean that this is a normal range for everyone – it depends on your historic period (we take a calculator for you further downwards on this page). A value of 10.5 in a teenager is perfectly normal, just ten.five in adult over age 35 is too loftier – this is hypercalcemia. The graph beneath shows the normal range of blood calcium in green and you can see that it changes as we become older. Teenagers and young adults tin can have normal calcium levels up into the mid 10s (mg/dl). But adults over the age of about 35 should have lower calcium levels, not going above 10.0 mg/dl. (NOTE: Canadian and European version of this graph is at the lesser of this page). Developed calcium levels usually range somewhere between 9.0 and 10.0 mg/dl, which is why we like to say that "adults live in the 9s". Information technology is typically non normal for adults to have frequent or persistent calcium levels in the 10s.

Hypercalcemia changes as we age. The green area shows the normal range for blood calcium according to our age.

Hypercalcemia is almost always caused by Hyperparathyroidism

Hypercalcemia can be caused by merely a few things. Often people are told that hypercalcemia is caused past cancer, but this is extremely rare. We have an unabridged page on the unlike causes of hypercalcemia (including different types of cancer) that yous can read (click here), simply it is of import to understand that over 99% of cases of hypercalcemia are caused past a parathyroid gland tumor; a disease called hyperparathyroidism.

People with parathyroid disease (hyperparathyroidism) virtually ever have hypercalcemia: they take blood calcium levels in the 10s or higher. The graph below shows highest calcium levels for over 20,000 consecutive adults with parathyroid disease who were treated at our heart. Near one-half of patients with hyperparathyroidism (a parathyroid tumor causing hypercalcemia) accept calcium levels betwixt ten.0 and 11.0 mg/dl, and half take calcium levels above 11.0 mg/dl.

What's wrong with hypercalcemia? Don't I need lots of calcium for my bones?

Hypercalcemia is non proficient, and actually, can exist quite bad for you lot. It is now known that fifty-fifty mild elevations in blood calcium (mild hypercalcemia) tin exist very detrimental to your overall health over time. The high blood calcium can crusade many issues with many dissimilar parts of the body, but it also makes people feel bad.

Hypercalcemia will cause symptoms in almost everyone. The virtually common symptoms of hypercalcemia are chronic fatigue, lack of energy, loss of interest in things you used to enjoy, "encephalon fog" or difficulty concentrating, and trouble with sleep. Information technology also causes kidney stones, heartburn or gastric reflux (GERD), headaches, depression, high blood pressure, palpitations or cardiac arrhythmias, and chronic kidney failure. And because calcium is coming out of your bones, it causes a loss in os density, leading to osteopenia and osteoporosis. Hypercalcemia can make you miserable. The about popular page of this large website is the Symptoms of Hyperparathyroidism folio.

Here is the almost important thing to know about the symptoms of hypercalcemia: they are NOT correlated with how high the calcium is. That is, someone with simply a slightly high calcium can feel just every bit bad every bit someone with a much higher blood calcium level, and they will have the aforementioned chances of getting all of the complications. Some doctors out there do not know this! In medical school they were taught that the calcium level determined how bad the affliction was, so a balmy hypercalcemia meant a mild disease and worse hypercalcemia meant worse problems. In treating tens of thousands of patients with hyperparathyroidism, nosotros know this is not true. Balmy hypercalcemia is just as bad as more pronounced hypercalcemia. This is illustrated very nicely in the graph below where nosotros looked at over 20,000 patients operated on for hyperparathyroidism and hypercalcemia. It shows that people with simply balmy elevations of blood calcium (between 10 and 11 mg/dl) have just as many symptoms and complications from the high calcium as people with much higher calcium levels (to a higher place xi.1 mg/dl).

Hypercalcemia: Frequency of common symptoms and complications of Hyperparathyroidism

Hypercalcemia Causes: An Overview

Hypercalcemia is almost always acquired by a parathyroid tumor (called primary hyperparathyroidism). Parathyroid glands are tiny endocrine glands in your cervix, adjacent to your thyroid. You have 4 of them, and the simply affair they practise is control blood calcium levels. They practice this past making parathyroid hormone (PTH), which raises the blood calcium level past taking calcium out of your bones. A normal parathyroid gland will produce just enough PTH to proceed your blood calcium level in normal range. A parathyroid tumor will produce more PTH than necessary, which will push button the calcium level upwardly. Parathyroid tumors are benign in almost every case, so yous don't demand to worry virtually cancer.

If y'all accept been told that y'all have hypercalcemia, the overwhelming odds are that you take a parathyroid tumor. There are a few other causes of hypercalcemia, which you can read about on our page on Causes of High Blood Calcium, just they are much, much less common. Hypercalcemia is virtually always due to a parathyroid trouble.

Hypercalcemia Diagnosis

Hypercalcemia is diagnosed by a blood calcium test. If the calcium is loftier, then yous have hypercalcemia. The next step is to figure out what the crusade of hypercalemia is. Since almost all hypercalcemia is caused by a parathyroid problem, the obvious next pace is to measure the corporeality of parathyroid hormone (PTH) in the blood. This is a elementary claret exam. If you lot have hypercalcemia and a PTH level that is in the high or normal range, and then you have a parathyroid tumor. Note that a loftier PTH level isn't required to brand the diagnosis of hyperparathyroidism every bit the cause of the hypercalcemia—but the PTH level can't be low. Scans, x-rays, and imaging tests are NOT to be used to diagnose hyperparathyroidism -- it is diagnosed on claret tests lone. We have two very excellent pages on the diagnosis of hyperparathyroidism: 1) The Diagnosis of Hyperparathyroidism, and 2) Avant-garde Diagnosis Tricks for Hyperparathyroidism.

Hypercalcemia Treatment

Since hypercalcemia is about always due to a parathyroid tumor, and there are no medications that can treat this – the handling is to remove the tumor. Fortunately, parathyroid surgery is curative and tin be done in a minimally invasive outpatient operation. Removing the parathyroid tumor is the only mode to cure almost every case of hypercalcemia.

Everyone with primary hyperparathyroidism is a candidate for this operation. Every bit mentioned to a higher place, even "mild" hypercalcemia will lead to bug if left untreated. There is no reason to wait for these complications to occur. Go the tumor out of your cervix before information technology does damage! Read some of our patient testimonials to learn about how this simple operation tin can be life-irresolute.
