What is hypocalcemia? Hypocalcemia is a condition in which there are lower-than-average levels of calcium in the liquid part of the blood, or the plasma. Calcium has many important roles in your body:
Hypocalcemia may be the result of low calcium production or insufficient calcium circulation in your body. A deficiency of magnesium or vitamin D is linked to most cases of hypocalcemia. Some people don’t have any symptoms or signs of hypocalcemia. As it affects the nervous system, babies with the condition may twitch or tremor. Adults who do have symptoms may experience:
The symptoms of severe hypocalcemia are:
The long-term symptoms of hypocalcemia include:
The most common cause of hypocalcemia is hypoparathyroidism, which occurs when the body secretes a less-than-average amount of parathyroid hormone (PTH). Low PTH levels lead to low calcium levels in your body. Hypoparathyroidism can be inherited, or it can be the result of surgical removal of the thyroid gland or cancer of the head and neck. Other causes of hypocalcemia include:
People with a vitamin D or magnesium deficiency are at risk of hypocalcemia. Other risk factors include:
Newborn babies are at risk because their bodies aren’t fully developed. This is especially true for children born to diabetic mothers. The first step in diagnosis is a blood test to determine your calcium levels. Your doctor may also use mental and physical exams to test for signs of hypocalcemia. A physical exam may include a study of your: A mental exam may include tests for:
Your doctor may also test for Chvostek’s and Trousseau’s signs, which are both linked to hypocalcemia. Chvostek’s sign is a twitching response when a set of facial nerves is tapped. Trousseau’s sign is a spasm in the hands or feet that comes from ischemia, or a restriction in blood supply to tissues. Twitching or spasms are considered positive responses to these tests and suggest neuromuscular excitability due to hypocalcemia. Some cases of hypocalcemia go away without treatment. Some cases of hypocalcemia are severe and can even be life-threatening. If you have an acute case, your doctor will most likely give you calcium through your vein, or intravenously. Other treatments for hypocalcemia include: MedicationsMany hypocalcemia cases are easily treated with a dietary change. Taking calcium, vitamin D, or magnesium supplements, or eating foods with these can help treat it. Home careSpending time in the sun will increase your vitamin D levels. The amount of sun needed is different for everyone. Be sure to use sunscreen for protection if you’re in the sun for a long time. Your doctor may recommend a calcium-rich diet plan to help treat it as well. The symptoms often go away with proper treatment. The condition is rarely life-threatening. In many cases, it goes away on its own. People with chronic hypocalcemia may need medication throughout their lives. People with hypocalcemia are at risk of developing osteoporosis because their bones release calcium into the bloodstream, instead of using it. Other complications include:
Maintaining healthy calcium levels in your body is key to preventing this condition. Eat calcium-rich foods and if you don’t get enough vitamin D or magnesium, you may need to add supplements of them to your diet, as well as calcium supplements.
