Low potassium

[Shelly15]

So my friends sister (she was 17) passed away a few years ago because of heart faliure, I never asked any questions because of my health anxiety but today I found out it was because she had low potassium levels and I'm freaking out! I stupidly googled the symptoms and everything it says I basically have. I'm trying to just tell myself all my symptoms are anxiety but it's really hard when I feel so ill all the time.

Does anyone have low potassium or no anything about it?

Very very low potassium can cause heart arythmias leading to cardiac arrest but this is unbelievably rare and usually due to some other underlying serious illness.

I had always had bordeline below normal potassium levels on blood test . 2 years ago I changed my diet for weight loss and started eating beetroot and watercress daily and 6 months later my next potassium blood test showed my level was bang middle of normal for first time so the diet change improved my levels.

A simple kidney function test will tell you your potassium level so maybe ask for this to put your mind at rest. In the meantime keep eating the bananas/ beetroot and watercress

I had a blood test for thyroid and iron levels, would it show up if I had low potassium in them?

It's a standard blood test so probably depending on what actual tests they ordered
