in the last 4 days my 85 year old dad has had blurry vision within 30 minutes of eating his noon time meal and felt dizzy.  he has normally low blood pressure and takes midrodrine for it. i took him to urgent care to be checked and they did find anything abnormal and suggested he take a baby asprin every morning until he can get a vascular work up of the veins in his neck and skull. we just checked his blood sugar level and it is 113. he is supposed to fly on 6/4/13 and on 6/5/13, is this going to be a problem and what is your opinion of all this?
