What are the causes of Low Potassium Level?

Potassium is an electrolyte (mineral). It is needed for cells to function properly. You get potassium through food. The kidneys remove excess potassium through the urinary system to keep a proper balance of the mineral in the body.

Common causes of low blood potassium include:

  • Medicines, such as diuretics (water pills), certain antibiotics (amphotericin B, chloroquine at toxic levels)
  • Diarrhea or vomiting
  • Eating disorders (such as bulimia)
  • Hyperaldosteronism
  • Laxative overuse, which can cause diarrhea
  • Chronic kidney disease
  • Low magnesium level
  • Sweating
  • Genetic disorders, such as hypokalemic periodic paralysis, Bartter syndrome
What are the symptoms of Low Potassium Level?

A small drop in the blood potassium level often does not cause symptoms or causes mild to moderate symptoms, which may include:

  • Constipation
  • Feeling of skipped heart beats or palpitations
  • Fatigue
  • Muscle damage
  • Muscle weakness or spasms
  • Tingling or numbness

A large drop in the blood potassium level may lead to abnormal heart rhythms, especially in people with heart disease. This can cause you to feel lightheaded or faint. A very low blood potassium level can even cause your heart to stop.

What are the current treatments for Low Potassium Level?

If your condition is mild, your provider will likely prescribe oral potassium pills. If your condition is severe, you may need to get potassium through a vein (IV).

If you need diuretics, your provider may:

  • Switch you to a form that keeps potassium in the body. This type of diuretic is called potassium-sparing.
  • Prescribe extra potassium for you to take every day.

Eating foods rich in potassium can help treat and prevent low level of potassium. These foods include:
