Your Care Instructions
Hypokalemia (say "hy-po-kuh-LEE-mee-uh") is a low level of potassium. The heart, muscles, kidneys, and nervous system all need potassium to work well.
This problem has many different causes. Kidney problems, diet, and medicines like diuretics and laxatives can cause it. So can vomiting or diarrhea. In some cases, cancer is the cause. Your doctor may do tests to find the cause of your low potassium levels.
You may need medicines to bring your potassium levels back to normal. You may also need regular blood tests to check your potassium.
If you have very low potassium, you may need intravenous (I.V.) medicines. You also may need tests to check the electrical activity of your heart. Heart problems caused by low potassium levels can be very serious.
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 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.
How can you care for yourself at home?
- If your doctor recommends it, eat foods that have a lot of potassium. These include fresh fruits, juices, and vegetables. They also include nuts, beans, and milk.
- Be safe with medicines. If your doctor prescribes medicines or potassium supplements, take them exactly as directed. Call your doctor if you have any problems with your medicines.
- Get your potassium levels tested as often as your doctor tells you.
