Julie I have a medi alert for that reason, it states no sugar, no ibufen and something about the tube thing and also that I have had a gastric bypass. If anything happens to me the emergency services can ring then and give my reference number and it will give them details of my gp and my surgeon they also call my hubby or son to let them no where I am and what has happened, I got the chain, tag, engraving, a card for my purse, key ring and stickers for my mobile and my passport and it only costs £12.95 a year which is cheap for the piece of mind it gives me.
