When You're in the Hospital
Your body needs calcium so that you can use your muscles. Calcium also keeps your bones and teeth strong and your heart healthy.
Hypercalcemia means you have too much calcium in your blood. Your blood calcium level may get too high due to:
- Certain kinds of cancers
- Problems with certain glands
- Too much vitamin D in your system
- Being on bed rest for a long time
When you were in the hospital, you were given fluids through an IV and drugs to help lower the calcium level in your blood. If you have cancer, you may have had treatment for that, as well. If your hypercalcemia is caused by a gland problem, you may have had surgery to remove that gland.
After you go home, follow your health care provider's instructions about making sure your calcium level does not get high again.
You may need to drink a lot of liquids.
- Make sure you drink as much water every day as your provider recommends.
- Keep water next to your bed at night and drink some when you get up to use the bathroom.
DO NOT cut back on how much salt you eat.
Your provider may ask you to limit foods with a lot of calcium, or not to eat them at all for a while.
- Eat fewer dairy foods (such as cheese, milk, yogurt, ice cream) or DO NOT eat them at all.
- If your provider says you can eat dairy foods, DO NOT eat those that have extra calcium added. Read the labels carefully.
To further keep your calcium level from getting high again:
- DO NOT use antacids that have a lot of calcium in them. Look for antacids that have magnesium. Ask your provider which ones are OK.
- Ask your doctor what medicines and herbs are safe for you to take.
- If your doctor prescribes medicines to help keep your calcium level from getting too high again, take them the way you're told to. Call your doctor if you have any side effects.
- Stay active when you get home. Your provider will tell you how much activity and exercise are OK.
You will probably need to get blood tests after you go home.
Keep any follow-up appointments you make with your provider.
