Hypercalcemia
Hypercalcemia is raising the serum calcium level, by increasing calcium absorption from food, but in many cases from resorption which is mobilization of bone-matrix-fixed calcium into ionized form which circulates dissolved in the blood plasma. If hypercalcemia is severe enough blood vessels, kidneys, the stomach wall and lungs are mineralised/calcificated, leading to heart problems, bleeding, and possibly kidney failure. [1] Although most Doctors don’t run an ionized calcium test, even this test can leave one vulnerable because "The first sign of vitamin D toxicity is hypercalcuria (excess calcium in the urine), not hypercalcemia (excess calcium in the blood)." [2]
Many people suffer mild hypercalcemia taking excess Vitamin D. You can’t simply rely on the Calcium test because it’s typically the wrong form, it’s not the first sign, and it’s a serum test. Less than 2% of Ca is in serum. “Mild hypercalcemia in patients followed up for more than 2 decades is accompanied by premature cardiovascular death despite trends to spontaneous resolution.” [3-5]
Mild hypercalcemia is often asymptomatic. This is a serious risk with supplementing Vitamin D. “Mild prolonged hypercalcemia may produce mild or no symptoms, or recurring problems such as kidney stones.” [6]
Pretty important message here: "Hypercalcemia state continues for several months when D2 or D3 are responsible for the toxicity whereas the hypercalcemia would subside in a week when 1 alpha(OH) D3 or 1,25 (OH)2D3 are responsible for the toxicity." [7,8]
It’s very important to consider where the increased blood calcium comes from when taking vitamin D. When there's not enough calcium in your diet, the body pulls calcium from bone, by what's called "resorption", and moves it to the blood to feed to cells. Resorption occurs from excess vitamin D, which is the biological mechanism seen in rodenticide. 'Excessive vitamin D causes marked and prolonged high calcium by accelerating intestinal calcium absorption and also removal of bone.” [9]
“There are multiple clinical manifestations of hypercalcemia and several causes of hypercalcemia. Hypercalcemia caused by milk-alkali syndrome is increasing in frequency.” Most people have never even heard of this syndrome, but apparently it needs to be something Doctors should be familiar with:
