hi, my name is Patti. my father in law is staying with us for awhile, he is 86 years old, has had a heart attack a few years back, also triple bypass surgery. Today he had breakfast then a few hours later he was trowing up, shaky and dizzy. He is on a low dose asperin and a pill for high blood pressure. I felt he was dehydrated and got him to drink some liquids( all he will drink is coffee) so he was not happy about drinking water. Not sure what to do next. He checked his blood sugar(106) and his blood pressure(180/93)
