summary

Spring is really a high incidence season of ten thousand diseases. People should be more careful about every disease in clinic. I think we all know, because a little inattention may bring great harm to their own health. For example, the disease of hypokalemia is often characterized by weakness and lethargy of the body, which is largely ignored by people. However, this kind of disease, which is extremely harmful, can often lead to life-threatening if it is not treated in time. Therefore, it is very important to recognize the symptoms of hypokalemia in time. So, what are the clinical symptoms of hypokalemia?

What symptom does hypokalemia have

First, neuromuscular system is characterized by neuromuscular stress. When serum K + < 3.0 mmol / L, muscle weakness of limbs can appear. Muscle weakness usually starts from both lower limbs and extends to both upper limbs. It is symmetrical on both sides, and is heavier at the proximal end. When serum K + < 2.5 mmol / L, soft paralysis can appear, with the most prominent muscles of limbs and slow or disappeared tendon reflex. When the respiratory muscles are involved, it can cause dyspnea. The symptoms of central nervous system were depression, fatigue, apathy, drowsiness, unconsciousness and even coma.

Second: the lack of potassium in the digestive system can cause the intestinal peristalsis to weaken. The mild cases have anorexia, nausea and constipation. The severe hypokalemia can cause abdominal distension and paralytic bowel obstruction.

Third: cardiovascular system hypokalemia, generally for myocardial excitability enhancement, can appear palpitation, arrhythmia. Severe cases may have atrioventricular block, ventricular tachycardia and ventricular fibrillation, and finally cardiac arrest in systolic state. In addition, it can also cause the decrease of myocardial tension, cardiac enlargement, peripheral vascular dilatation, blood pressure drop and so on.
