Is hyperkalemia dangerous?

Is hyperkalemia dangerous?

Hyperkalemia: Hyperkalemia can be dangerous. It is not just the level that is important, it is how quickly the potassium (k) was raised. Patients with chronic kidney disease can walk around with a k of 5.5 with no problems, as their hearts are used to that k level. Auto accidents can cause acute elevations of k in normal people and they can have some problems by going from a k of 3.8 to 5.1. ...Read more

Hyperkalemia (Definition)

Hyperkalemia in an elevated potassium level in the blood. It can be mild to severe. The most common causes are kidney disease, Addison's disease, dehydration, and multiple drug therapies. It can occur in crush injuries and rhabdomyolysis (rapid breakdown of muscle) or hemolysis (breakdown of blood cells). Severe hyperkalemia can be fatal and cause the heart to stop beating or become very slow. It is usually treated by resin exchange agents (Kayexalate or others) or dialysis and fluids. Sometimes glucose, Insulin and sodium bicarbonate can be utilized as ...Read more
