how much potassium is low
Normal serum potassium levels range from 3.5 to 5.0 mEq/liter in the blood. Normal daily intake of potassium is 70-100 mEq (270 to 390 mg/dl), and requires the kidneys to remove that same amount each day. If more is removed, the body's total potassium store will be decreased, and the result is hypokalemia (hypo=low + kal=potassium +emia= in the blood) occurs.
