Potassium and sodium are important substances in the body to maintain life metabolism. Patients with hypokalemia and hyponatremia may have reactions such as muscle weakness, hypertension and palpitation. 1. Muscle weakness: The obvious symptom of patients with low blood potassium and low blood sodium is generalized muscle weakness, and the proximal joints are mainly weak, and they may not be able to lift their arms or legs to walk. 2. High blood pressure: Potassium has the effect of relaxing the walls of blood vessels, and the mineral is very important for cardiovascular health. Insufficient potassium in the diet will cause vasoconstriction, which may lead to elevated blood pressure. 3. Palpitations: Patients with low potassium and low sodium will have increased heart excitability and abnormal rhythm, which may lead to palpitations, panic, arrhythmia and even cardiac arrest in some patients. It is recommended that patients with hypokalemia and hyponatremia should consult a doctor in time to clarify the cause of the disease and receive reasonable treatment under the guidance of a physician.
