Hypokalemia

What is hypokalemia?

Hypokalemia is a low level of potassium in your blood. Potassium helps control how your muscles, heart, and digestive system work. Hypokalemia occurs when your body loses too much potassium or does not absorb enough.

What causes hypokalemia?

  • A diet that is low in potassium

  • Drinking too much caffeine

  • Medicines, such as diuretics (water pills), blood pressure medicines, or antibiotics

  • Dehydration from diarrhea, vomiting, or heavy sweating

  • Medical conditions, such as Cushing syndrome or kidney problems

What are the signs and symptoms of hypokalemia?

  • Tiredness

  • Constipation

  • Fast or irregular heartbeats

  • Frequent urination or urinating large amounts

  • Muscle twitching or skin tingling

  • Muscle weakness

How is hypokalemia diagnosed?

  • An EKG test records your heart rhythm and how fast your heart beats. It is used to check for irregular heartbeats.

  • Blood tests are done to check your potassium level.

How is hypokalemia treated?

You will receive potassium to bring your levels back to normal. This may be given as a pill or IV. The amount of potassium you are given will depend on the potassium level in your blood.

How can I manage my symptoms?

Eat foods that are high in potassium, such as bananas, tomatoes, oranges, turkey, and milk. Orange juice, citrus juices, and tomato juice are also high in potassium. Avoid caffeine. You may need to meet with a dietitian to help plan the best meals for you.
