High calcium levels in the blood hypercalcemia often signal serious medical conditions. The most common causes of hypercalcemia are hyperparathyroidism and cancer.
Read to understand what else can cause high blood calcium levels. Chronic hypercalcemia carries several health risks, including poor kidney function, heart disease, coma, and even death [ 123 ]. Taking in more calcium from food and supplements is unlikely to substantially raise your blood levels.
It may cause other problems, such as constipation, or reduce the absorption of other minerals including iron and zinc. But since calcium is the most abundant mineral in the body, its levels are tightly controlled independently of your dietary intake [ 14 ]. Common symptoms of hypercalcemia include [ 5 ]:. Hypocalcemia can be dangerous and you should seek urgent medical help if you experience the listed symptoms.
Read more about the blood calcium test here. The normal range of blood calcium is around 8. These values can vary slightly from lab to lab.
Hypercalcemia is defined as total blood calcium over Your doctor will interpret your result, taking into account your medical history, symptoms, and other test results. Causes shown here are commonly associated with high calcium levels. Work with your doctor or another health care professional to get an accurate diagnosis. Hyperparathyroidism or an overactive parathyroid gland is the most common cause of hypercalcemia.
This can happen when one or more of the parathyroid glands become enlarged, either benignly or due to cancer [ 9 6. what is the meaning of the word tessellation, 10 ]. Calcium blood levels are controlled by parathyroid hormone PTH.
Cells in your parathyroid gland — located in the neck just behind the thyroid — release PTH when they sense a drop in calcium blood levels [ 11 ]. PTH raises blood calcium levels by increasing the absorption of calcium from the gut and kidneys. This hormone also mobilizes calcium and phosphate from the bones: that is, it breaks down and frees the how to open dumpster door content of bones to compensate for low calcium levels.
What happened to cuddy on house season 8 process is known as bone resorption [ 11 ]. PTH also increases the amount of vitamin D that is converted to its active form, calcitriol.
Calcitriol increases calcium absorption in the gut [ 11 ]. Some studies suggest that hyperparathyroidism may often go unrecognized. You may need to see an endocrinologist to further examine your parathyroid gland and to discuss your lab results [ 12 ].
Aside from cancer of the parathyroid gland, other types of cancers can also cause hypercalcemia by releasing a protein that mimics PTH.
These include lung, ovary, and kidney cancer [ 910142 ]. Cancers that spread to the bones and go on to damage bone cells can also excessively raise blood calcium levels [ 910142 ]. Certain medications may cause or contribute to hypercalcemia.
What airport is closest to taj mahal in india overdose of vitamin D can cause hypercalcemia.
This condition is known as hypervitaminosis D. Vitamin D can raise calcium levels since it increases the amount of calcium absorbed in the gut. This usually happens only when you take excessively high levels for a prolonged amount of time 20, —IU per day for at least a month [ 14212223 ]. Even if you get too much sun, the sunlight will degrade any excess vitamin D and prevent hypervitaminosis [ 24 ].
The only risk of overdose comes from megadosing vitamin D supplements. Vitamin A overdose can also lead to hypercalcemia. This usually only happens if you take high-dose vitamin A supplements for a long time. Severe dehydration can falsely increase total calcium levels, whereas ionized calcium may remain normal [ 25 ]. Your doctor can also rule this out by checking your ionized free calcium levels.
An overactive thyroid hyperthyroidism can cause hypercalcemia too. The mechanism is poorly understood. Some evidence suggests the following changes occur in hyperthyroidism:.
The result of these changes is an increased mobilization of calcium and phosphate from bones bone resorption [ 926272829 ]. Prolonged immobilization can result in hypercalcemia and osteoporosis. This likely happens due to a suppression of the parathyroid-1,dihydroxyvitamin D axis [ 301625 ]. Hypercalcemia has been reported in some infections, such as tuberculosis, HIV, or cytomegalovirus, probably due to bone resorption [ 25 ].
Hypercalcemia is a complication of what happens when calcium levels are high, an inflammatory disease that attacks several organs in the body.
In sarcoidosis, the production of active vitamin D is out of control while parathyroid hormone levels can also be increased. This causes calcium levels to surge [ 3435363738 ]. Taking too much calcium is uncommon but possible. It has gta iv how to call a taxi xbox 360 reported in people who take large doses of calcium carbonate g daily along with alkaline substances, such as milk, bicarbonate or antacids.
The system becomes overwhelmed and cannot excrete calcium fast enough. The phenomenon is known as milk-alkali syndrome [ 3918 ]. Below is shown the maximum daily levels of calcium that you should not go beyond. This includes calcium from foods as well as supplements. Going over this level for a short while is unlikely to cause any issues, but doing so long term is unsafe [ 1 ].
Magnesium is necessary for controlling calcium levels in the blood. It is also a co-factor in the production and activation of vitamin D. Evidence suggests that the optimal ratio ismeaning that you need twice as much calcium as magnesium. Meanwhile, getting more than that — for example, 4 times more calcium than magnesium — has been linked to numerous chronic diseases [ 40 ].
It turns out that our modern lifestyle has shifted the balance in favor of calcium. Alternatively, you can also discuss magnesium supplements with your doctor [ 40 ].
Genetics certain mutations in your genes can also be responsible for high blood calcium levels. An example is a disorder called familial hypocalciuric hypercalcemia [ 4116 ].
Dogs and cats can also get hypercalcemia, roughly for the same reasons as humans. Frequent symptoms of hypercalcemia in dogs and cats include [ 42 ]:. If you suspect your cat or dog has hypercalcemia, take them to a veterinarian as soon as possible. Chronic or severe hypercalcemia should always be treated by a doctor. For more information about decreasing blood calcium levels read this post.
High blood calcium levels are what happens when calcium levels are high due to an underlying disease or disorder. The two most common causes are overactive parathyroid gland and cancer. Your doctor will determine your levels by ordering a calcium blood test, along with other markers if needed. Certain drugs, as well as high vitamin A how to keep a man the play vitamin D intake, may also cause hypercalcemia.
Consuming too much calcium is unlikely to raise your blood levels, but it can happen under certain conditions. Joe Cohen won the genetic lottery of bad genes.
As a kid, he suffered from inflammation, brain fog, fatigue, digestive problems, anxiety, depression, and other issues that were poorly understood in both conventional and alternative medicine.

Causes of High Calcium Levels in the Blood
If your calcium levels are very high, you could get nervous system problems, including becoming confused and eventually unconscious. You'll usually find out that you have hypercalcemia through a Estimated Reading Time: 4 mins. Jun 02, · The overstimulation of parathyroid glands or any health condition can often disturb the balance of calcium in your body. If the calcium levels are too high, a condition called hypercalcemia may be diagnosed. This disease can interrupt the normal functions of Estimated Reading Time: 6 mins. However, in most patients, high calcium levels are caused by hyperparathyroidism, a condition when the parathyroid glands produce too much parathyroid hormone. High levels of parathyroid hormone leads to the movement of calcium from the bone and into the blood.
What to do if your blood calcium level is high The finding of a high blood calcium level is very common, occurring in millions of Americans each year. Sometimes, this will just be a single event related to a laboratory error or being dehydrated on the day the lab was drawn. However, quite frequently a high blood calcium level will mean that there is an important underlying problem.
In general, the first thing to do is re-check the level to confirm it. This is common sense. For example, if you heard a strange noise in your car, you would certainly listen for it again the next time you drove to double check if it was a real problem, right?
See Getting started: a word of caution regarding medical information on the internet. If your blood calcium level is high on more than one occasion, then it is probably time to get more serious about finding out why this is happening. Primary hyperparathyroidism is the most common cause of high blood calcium levels Figure 1. This pie chart shows the most common causes of chronically elevated blood calcium levels, meaning when the calcium test is high more than once over several months.
Other causes of high blood calcium are listed above and most commonly refer to hypercalcemia of malignancy high blood calcium levels due to cancer elsewhere in the body as described above and use of thiazide diuretics. Please note that renal failure chronic kidney disease can also cause high blood calcium levels but those patients were excluded from this analysis. If this has happened to you or a family member, you may wish to have the parathyroid hormone PTH level checked.
A high or inappropriately normal PTH level will frequently establish the diagnosis of primary hyperparathyroidism see Establishing the diagnosis of primary hyperparathyroidism. A low PTH level will suggest other causes of high blood calcium levels. The pie chart contains data derived from approximately 3. The population studied is similar in size to the population of the state of Ohio. Through this unique research collaboration, UCLA Endocrine Surgery has been able to study both high blood calcium levels and primary hyperparathyroidism in a completely new way, looking at large, racially diverse populations in great detail with respect to their health outcomes see How successful is parathyroid surgery?
