Does Low Potassium Make You Bruise Very Easily?

I didn't read anything about bruising, I don't remember doing that, but you can however suffer from hypokalemia which can be fatal if not taken care of quickly, it typically results from diarrhea, increased diuresis and vomiting.
Other symptoms of low potassium can include, muscle weakness, paralytic ileus, and ECG abnormalities. There are other things that you need to look out for as well.
Such as respiratory paralysis. If your doctor did a blood test, and told you that you have this, he should have told you how to treat this, and what you can eat to  bring potassium up in your system.
Though he probably did give you some tablets for a quick boost of it into your system, you can find it in potatoes, bananas, orange juice, and broccoli, there are other foods as well. Go to www.wikipedia.org and you can read further there.
In the contents box, you will find several topics that you should pay attention to, and read them carefully. Hope this helps, good luck.
