You have been diagnosed with hypercalcemia. That means you have too much calcium in your blood. Calcium is a mineral. It helps grow your bones and teeth. It also controls your heart rhythm and lets your muscles contract. Hypercalcemia is often the result of other problems. These include overactive glands, unhealthy bones, long-term bed rest, and some kinds of tumors or cancers.

Ask your doctor how much fluid you should drink. You may need to drink 3 quarts to 1 gallon (3 to 4 liters) of fluid every day. Drink as much as directed by your doctor. Keep track of how much fluid you drink. For example, put a full gallon of water in your refrigerator each morning. Make sure you drink it throughout the day. Check your progress.

You'll need to cut back on foods that are high in calcium. Read food labels. Don't buy dairy products with added calcium. Limit or stop your intake of:

• Milk.
• Cheeses.
• Yogurt.
• Pudding.
• Ice cream.
• Calcium-fortified orange juice.
• Calcium-fortified soymilk.
• Calcium-fortified ready-to-eat cereals.
• Canned salmon or sardines with soft bones.

Also:

• Don't take antacid medicines if they list calcium as an ingredient. Many antacids contain calcium. Some contain magnesium and no calcium.
• Don't take vitamin D supplements (more than 800 international units a day) or multivitamin-mineral supplements that also contain calcium, unless prescribed by your doctor.
• Don't limit your salt intake.
• Get exercise. If your hypercalcemia was caused by long-term bed rest, try to increase your activity, if possible. Your doctor may decide to add physical therapy if you have been on long-term bed rest and need to start increasing your activity level.
• Resume your normal activities as directed by your doctor.
• Take your medicines exactly as directed.
• Tell your doctor about any other medicines you are taking. This includes over-the-counter or herbal medicines and supplements.

Keep all appointments for blood tests and follow-up care. Your doctor needs to watch your condition closely.

Contact your doctor right away if you have:

• Extreme fatigue.
• Loss of appetite.
• Trouble urinating or pain when urinating.
• Blood in your urine.
• Vomiting or diarrhea.
• Increased thirst.
• Irregular heartbeat.
• Dizziness or lightheadedness.
• Depression.
• Confusion.
