In addition to osteoporosis, hyperthyroidism can cause blood calcium levels to rise (hypercalcemia) by as much as 25%. Occasionally, this may be severe enough to cause stomach upset, excessive urination, and impaired kidney function.

Causes of hypocalcemia include the following: A low level of parathyroid hormone (hypoparathyroidism), as can occur when the parathyroid glands are damaged during thyroid gland surgery. Lack of response to a normal level of parathyroid hormone (pseudohypoparathyroidism)

High phosphorus levels can cause damage to your body. Extra phosphorus causes body changes that pull calcium out of your bones, making them weak. High phosphorus and calcium levels also lead to dangerous calcium deposits in blood vessels, lungs, eyes, and heart.

When the calcium in our blood goes too low, the parathyroid glands make more PTH. Increased PTH causes the body to put more calcium into the blood. Increased PTH causes the bones to release their calcium into the blood.

Hypocalcemia (Low Level of Calcium in the Blood) In hypocalcemia, the calcium level in blood is too low. A low calcium level may result from a problem with the parathyroid glands, as well as from diet, kidney disorders, or certain drugs.

If too much calcitonin is found in the blood, it may be a sign of a type of thyroid cancer called medullary thyroid cancer (MTC). High levels may also be a sign of other thyroid diseases that can put you at a higher risk for getting MTC.

Any disorder that leads to high levels of calcium in the blood or urine may lead to nephrocalcinosis. In this disorder, calcium deposits in the kidney tissue itself. Most of the time, both kidneys are affected. Nephrocalcinosis is related to, but not the same as, kidney stones (nephrolithiasis).

The most common cause of high B12 in the blood is due to recent ingestion or injection of supplemental vitamin B12. We don't worry about overdosing on B12 supplements because excess can be excreted in your urine. It could also be possibly from your diet if high in animal products such as meat, eggs, and shellfish.

Parathyroid hormone (PTH) is an important contributor to the bone remodeling process. High levels of PTH can activate osteoclasts and cause excessive bone breakdown. Calcium in your blood triggers the release of PTH. Low calcium levels in the blood, or hypocalcemia, can cause high levels of PTH.

Causes of Hypercalcemia in Dogs and Cats In cats, idiopathic hypercalcemia appears to be the most frequent cause of a high total calcium concentration, followed by renal failure and malignancy. Ionized hypercalcemia in conjunction with chronic renal failure is more common in cats than dogs.

If urine calcium levels are too high or too low, it may mean you have a medical condition, such as kidney disease or kidney stones. Kidney stones are hard, pebble-like substances that can form in one or both kidneys when calcium or other minerals build up in the urine. Most kidney stones are formed from calcium.
