a friend of mine just have a retinal detachment, she is diabetic. she was advised by the doctor to rest, after the operation she had just 3 days ago, she have been on the bed, she have reduced her food intake since the operation, during the doctor visit, patient sugar found quite high. So, would like to find out what should we do to help reduce her sugar count? I understand that exercise does help reduce the sugar, and I know that whatever she does will affect her eye's veins....your advice will be highly appreciated.
