Another suggestion until a medical alert bracelet, necklace or keychain can be ordered is to put the information in your cell phone. I can think of 2 places to enter it. You can make it the first contact in your list by enterinG AAA-I HAD GASTRIC BYPASS ON XX/XX. Then you have to enter a phone number, I just enter 1-111-1111. The other place you can put the information is in notes section and enter as much info as will fit.
