Whether it is hereditary or acquired, hypoparathyroidism is treated with calcium and vitamin D supplements to maintain a normal level of calcium in the blood. Vitamin D is necessary because it helps your body to absorb calcium. The supplements may need to be taken for the rest of your life, and your blood must be tested regularly to ensure that proper levels of calcium and vitamin D are being maintained. Regular checkups are important. Episodes of tetany are treated with calcium given intravenously (into a vein), which provides quick relief of symptoms.
Medications called diuretics sometimes are given to prevent too much calcium from being lost through the urine, a problem that can lead to kidney stones. Diuretics will reduce the amount of calcium and vitamin D supplements you need.
