What does a high potassium level mean? what about a low potassium level?

High andLow Potasium: Both are abnormal, high pottasium may be due to taking pottasium orally.Certain medicines like ace inhibiters, arbs, or kiney insufficiency.Low pottasium can be due to use of diuretics or adrenal disease.If there are abnormal it needs to be corrected, they can cause cardiac arrythmia and muscle weekness if it is low.

Long list of answers: High k (potassium) can be from lab error, released from red cells or from taking in more than the kidneys can remove. Typically from kidney trouble. Some medications make this more possible. Low k is found in patients who are volume depleted, drugs such as Lasix (furosemide) can make this happen. Some kidney diseases lead to k loss. These problems need expert attention. K problems are serious.
