If electroyles are carried in your blood, then how do you loose them if you take laxitives?

Question

I was told that you can loose too many of your electroyles when taking too many laxitives. How is this possible if your not loosing blood? Same with bulimics.

Answer 1

Because taking too much laxitives can cause you to dehydrate, and that is what causes the imbalance of electrolytes, which could lead to heart failure.
