For patients with hyperkalemia, early symptoms include numbness in the limbs, weakness, muscle soreness, and paralysis. As the condition progresses, it can suppress myocardial function, reducing the tension of the myocardium and leading to slow heartbeats, and even cause arrhythmias and cardiac arrest. Increased release of acetylcholine can also cause nausea, vomiting, abdominal pain, and other symptoms. Patients with this condition generally also exhibit symptoms of hyperlipidemia and metabolic acidosis. For mild cases of hyperkalemia, temporary treatment may not be necessary, and symptomatic treatment such as stopping vomiting and drinking water may be sufficient. However, in acute cases, it is recommended that the patient immediately undergo dialysis or receive diuretic injections to rapidly eliminate potassium ions from the body, and to stop consuming foods and medications that contain potassium.
