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 (IV) 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.
