Hypokalemia (low level of potassium in the blood)

[Greta]

In hypokalemia, the level of potassium in blood is too low.

A low potassium level has many causes but usually results from vomiting, diarrhea, adrenal gland disorders, or use of diuretics.
A low potassium level can make muscles feel weak, cramp, twitch, or even become paralyzed, and abnormal heart rhythms may develop.
The diagnosis is based on blood tests to measure the potassium level.
Usually, eating foods rich in potassium or taking potassium supplements by mouth is all that is needed.
