Symptoms of hyperkalemia?

summary

The main clinical manifestations of hyperkalemia are cardiovascular system and neuromuscular system. The severity of the symptoms depends on the degree and speed of the increase of serum potassium, and whether there are other disorders of plasma electrolyte and water metabolism. Symptoms of hyperkalemia? Next, I'd like to share my views with you.

Symptoms of hyperkalemia?

High potassium can depress the heart muscle and reduce its tension, so it has bradycardia and heart enlargement, heart sounds weaken, arrhythmia easily occurs, but heart failure does not occur. ECG has characteristic changes, and it is related to the degree of serum potassium. When serum potassium was more than 5.5mmol/l, ECG showed shortened Q-T interval and symmetrical T wave height,

Early often limbs and mouth numbness, extreme fatigue, muscle soreness, limb pale, cold and wet. When the blood potassium concentration reached 7 mmol / L, the limbs were numb, soft paralysis, first trunk, then limbs, and finally affected respiratory muscles, resulting in asphyxia. The central nervous system can be characterized by restlessness or unconsciousness.

Hyperkalemia causes increased release of acetylcholine, which can cause nausea, vomiting and abdominal pain. Due to the toxic effect of high potassium on muscles, it can cause quadriplegia and respiratory arrest. All hyperkalemia have different degrees of azotemia and metabolic acidosis, the latter can aggravate hyperkalemia.

matters needing attention

Generally like melon and fruit vegetables (pumpkin, wax gourd, gourd), apple, pear, pineapple, watermelon, grape, potassium content is relatively low, edible. Foods high in potassium can be reduced by freezing, soaking in water or discarding the broth.
