Just been diagnosed with this. What a horror story!
I ended up in emergency last Tuesday morning at 4 am.
Your body loses salt and the symptoms are unreal.
You are supposed to be between 135 and 145. Mine dropped to 122. I got some awful symptoms. They gave me two days of salt via a drip.
I came home yesterday but today I feel worse. I’m not allowed any water at all. Other things have to be counted like yoghurt, tea, soft drink, etc.
This is terrifying!
