Hypercalcemia is too much calcium in the blood. You need calcium to have strong bones. It also helps your muscles, heart, and nerves work as they should. But too much is dangerous.
Several problems can cause too much calcium in the blood. It can happen because of medicines or certain health problems. Some diseases can make your intestines take in too much calcium. And some can take calcium from your bones. A non-cancerous tumour can grow in the glands that control calcium levels. And some cancers can cause high calcium levels.
These high levels may make you lose fluids (become dehydrated). You may get confused and very tired. Some people also have nausea, vomiting, and constipation. Your doctor will treat you based on how serious the problem is and what is causing it. Since too much calcium can be dangerous, it is important to treat it. You may get fluids to stop dehydration. You also may get medicine to help your body get rid of calcium through your urine or put it back into your bones. If a tumour is the cause, you may need surgery.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
