In rare cases, insulin overdose can cause enough potassium uptake into cells as to cause hypokalemia.

罕见案例中，胰岛素过量会造成足量的钾被细胞摄入，造成低钾血症。

Alright, so there are all these ways to develop hypokalemia, but what happens when somebody has hypokalemia?

好，这些就是所有形成低钾血症的途径了，但是当一个人患低钾血症时会发生什么呢？

Alright, on to external potassium balance shifts resulting in hypokalemia, which has to do with potassium intake or excretion.

好，那导致低钾血症的外部钾平衡的变化，和钾摄入和排泄有关。

Commonly used diuretics, like loop diuretics and thiazide diuretics, also increase potassium excretion and can lead to hypokalemia.

通常使用的利尿剂，比如袢利尿剂和噻嗪类利尿剂，也会增加钾的排泄，导致低钾血症。

Another external balance shift causing hypokalemia is increased losses of gastrointestinal secretions, typically due to vomiting and diarrhea.

另一种导致低钾血症的外部平衡变化是胃肠道消化液的大量丢失，典型原因是呕吐和腹泻。

But the loss of stomach acid leads to metabolic alkalosis, which as we saw, can lead to hypokalemia.

但是胃酸的丢失导致代谢性碱中毒，如我们所见，可以导致低钾血症。

Hypokalemia is defined as a serum potassium concentration lower than 3.5 millimeter liter.

低钾血症是指血清钾浓度低于3。5mm/L。

JW also has hypokalemia, or low potassium presence in blood because of that beer.

JW也有低钾血症，或者因为饮用大量啤酒导致血液中的钾被稀释。

In patients with severe hypokalemia, the main goal of treatment is to normalize potassium levels.

对于严重低钾血症的病人，治疗的主要目标是使得血钾水平正常。

Finally, hypokalemia can affect cardiac muscle contractions, which can lead to cardiac arrhythmias and cardiac arrest.

最后，低钾血症会影响心肌收缩，导致心律失常和心搏骤停。
