Just seen a news feed on the BBC about a woman in the US who died of "Water Intoxication". She was a doing a radio contest to drink lots of bottled water & hold it, in order to win a Nintendo Wii. Not being a medic I fail to see how water can kill you. Surely if you have consumed 6 litres of water you either pi$$ like a waterfall or feel somewhat uncomfortable. Can any medic type folk explain what water intoxification is please ?
