How to Lower Blood Calcium

by Will Guzzardi
  • Overview

    While the human body is capable of creating many of the chemical substances it requires, vitamins and minerals cannot be produced in the body and must be consumed through diet. Calcium is one such mineral, and it is vital for a number of life processes, including bone building. It's important to have enough calcium in the diet to have healthy bones, but excess calcium can be dangerous and may induce symptoms like nausea, muscle pain, confusion and fatigue.
 
  • Step 1

    Limit your intake of calcium and vitamin D. Vitamin D is the vitamin that allows the body to use calcium. For the most part, we take this vitamin in through the skin by exposure to the sun. If you're taking excessive vitamin D supplements, however, your blood calcium may be elevated. Limit your intake of calcium supplements, as well as calcium-fortified juices, milk, antacids and other products. It's unlikely that everyday sources of calcium, like dairy products, will on their own lead to high blood calcium, but if you consume too many products that have calcium added, this is a possibility.
  • Step 2

    Discuss your prescription medications with your doctor to see if they may be raising your blood calcium levels. Certain medications, especially blood pressure pills, may have the side effect of altering kidney function. Your kidneys may not release enough calcium into the urine, causing it to build up in the bloodstream. If this is the case, consider changing medications.
  • Step 3

    Have your doctor check for conditions that may lead to hypercalcemia, or an excess of blood calcium. The most common of these is hyperparathyroidism, or abnormal function of the parathyroid gland. This condition is not serious, can be treated easily with a simple surgery, and accounts for the vast majority of cases of hypercalcemia. In a few rare cases, however, certain cancers may cause high blood calcium, and a rare condition called sarcoidosis may also be at play. Your doctor will be able to run tests to determine if any of these conditions are affecting your blood calcium.
