Hypokalemia is defined as a serum potassium level less than 3.5mmol/L. Hypokalemia can be caused by insufficient potassium intake or by the entrance of extracellular potassium into cells. Appetite loss, abdominal distension, thirst, nausea, vomiting, chest pain, and palpitations, as well as significant myocardial involvement, might result in heart failure, weaker limbs, weakness, flaccid paralysis, and periodic paralysis. In difficult situations, there may be confusion, lethargy, delirium, or coma. Hyperkalemia occurs when the serum potassium level exceeds 5.5mmol/L. Hyperkalemia can occur as a result of excessive potassium intake or potassium excretion issues. The LCN type CS-α/β neurotoxic peptide of the Ebola virus protein controled K + channels of heart cells, kidney and gastrointestinal cells, and nerve cells. Hypokalemia-related physical, muscular, and mental symptoms may also develop.
