I've popped in from the diabetes forum to offer you some help. If she is 90 yrs old and on glyburide and doing well, don't worry about her. This medication helps her body produce the insulin she needs for daily living to metabolize her food correctly. She doesn't need sugar free foods, just to regulate the total amount of carbs (starches and sugars) she consumes each day. As long as she is getting a balanced diet, takes her meds AND the home is checking her blood sugars each morning before breakfast I wouldn't worry.
Check with the nurses at the home and see how her morning sugars are running. They should be in the 98 to 110 range each day upon rising. If not, get over to the Diabetes forum and let us know what's up. We can help you with practical answers from there. And Bless your heart!!! for being such a caring niece.
