DEAR DR CALDER.
I WAS FINALLY ABLE TO SEE YOUR ANSWER, BUT DID NOT SEE WHY GLIPISIDE WOULD RAISE MY BS. I DID MAKE NOTE OF THE MEDS YOU SUGGESTED TO DISCUSS WITH MY DOCTOR.
The answer to your question about glipizide is a good question that is difficult to answer without more specific data.
It was not clear to me from the the information provided exactly when you were testing your blood sugars.
Please read chapter 3 and 4 in my book , Diabetes Office visit , for more details on record keeping that will help you and your physician deal with the sometimes confusing ups and downs in home glucose test.
Fasting glucose test
A persistent increase in fasting glucose could mean that your diabetes has progressed to a new level of insulin deficiency and intermittent increases in the fasting sugar could mean that your sugar was to low at 2 to 3 AM . Did you check a 3 am glucose?
Glipizide could increase your sugar if there was a preceding low sugar.
Persistent high sugars before meals and bedtime suggest that you are no longer able to make enough insulin to handle the glucose from the previous meal or snack.
Testing after meals
Increases in after meal sugars can depend on where your glucose was before the meal and how much carbohydrate you had with the meal . if your glucose test was high before the meal then it will be higher after the meal.
Read the Feb. post discussing glucagon and it's effect on your blood sugar levels.
Generally after meal glucose test are of limited value for diabetics taking oral medications. Some of the new medication for type 2 diabetes help reduce after meal test by reducing glucagon levels and stimulating something called " glucose sensitive insulin release "
After meal sugar test are more useful for people taking insulin before each meal or snacks . The after meal glucose test helps them develop something called insulin / carbohydrate ratios. This ratio allows them vary the carbohydrates in a meal and to the adjust the dose of rapid acting insulin needed for that meal.
