Hyperkalemia and hyperkalemia share the same symptoms of neuromuscular symptoms, cardiovascular symptoms, and effects on the gastrointestinal tract. 1. Neuromuscular symptoms: Hyperkalemia and hyperkalemia will both lead to muscle weakness, and in severe cases, both will involve the respiratory muscles, leading to symptoms of respiratory distress. 2. Cardiovascular symptoms: Hypokalemia will lead to decreased permeability of myocardial cell membrane to potassium, and the patient will suffer from arrhythmia and ventricular fibrillation, while hyperkalemia will lead to decreased myocardial stress and arrhythmia, which will lead to ventricular fibrillation in severe cases. 3. Impact on gastrointestinal tract: Hyperkalemia may lead to the weakening of smooth muscle activity in gastrointestinal tract, which may cause nausea and vomiting, etc. Hyperkalemia may also cause nausea, vomiting and abdominal pain due to the increase of acetylcholine release. If patients have the above symptoms, they need to go to the hospital in time to determine whether it is hypokalemia or hyperkalemia, and then target treatment.
