Mild<unk>  is often without symptoms, although it may cause elevation of blood pressure, and can provoke the development of an abnormal heart rhythm. Severe<unk> , with serum potassium concentrations of 2.5–3 meq/L (Nl: 3.5–5.0 meq/L), may cause muscle weakness, myalgia, tremor, and muscle cramps (owing to disturbed function of skeletal muscle), and constipation (from disturbed function of smooth muscle). With more severe<unk> , flaccid paralysis and hyporeflexia may result. Reports exist of rhabdomyolysis occurring with profound<unk>  with serum potassium levels less than 2 meq/L. Respiratory depression from severe impairment of skeletal muscle function is found in some people. It can also cause psychotic as well as other mental symptoms.
