Brief Answer:
Don't worry ,your diabetes contol is OK.

Detailed Answer:
Hello dear
I have gone through your query.

Your have a very good A1C result. Well done!

Keeping your blood glucose levels as close to normal as possible can be a lifesaver. Tight control can prevent or slow the progress of many complications of diabetes.

There are some processes that can trigger morning highs:

-the XXXXXXX effect (or XXXXXXX phenomenon)
-waning insulin
-the Somogyi effect

Whatever the cause of morning highs, the source of the excess glucose is the same: the liver, the body's glucose storehouse and production center. So, you are right; the liver is involved.

Hormones signal the liver to keep the body fueled by releasing glucose into the blood between meals and overnight.

Hormone imbalances in diabetes ,too little insulin made by the body or taken as medication and too much of the hormones that counteract insulin(especially in the morning)—can cause the liver to pump out more glucose than it should.This is the cause of your high fasting blood glucose.

Nonalcoholic fatty liver disease is very common in type 2 diabetics especially if they are overweight or obese. In your case this condition is mild , so you have no reason to worry.

The solution for this condition is usually weight loss(if you are overweight) through a combination of a healthy diet and exercise regime.

My advice for you is to control your blood glucose at 3 :00 am (let me know your results of 2-3 measurements,so i can understand why you have high blood sugar some mornings.) and to vitamin E supplements(it can be helpful for your mild liver damage caused by nonalcoholic fatty liver disease.)

Hope my information was helpful.
If you have other questions, feel free to ask.I will be happy to help.
Take care..

By "controlling" my blood sugar at 3:00 am, do you mean I should do a blood sugar check at that time?

Brief Answer:
Yes,it is necessary to check your blood sugar at the middle of the night.

Detailed Answer:
Hi

To learn the reason for your high morning blood sugar,i ask you to check your levels between 2 a.m. and 3 a.m. for a few nights in a row.

If it’s consistently low during this time, the Somogyi effect is probably the cause.
If it’s normal or high during this time period, the XXXXXXX phenomenon is more likely the reason.

Let me know your results because if we find the cause of your high morning blood glucose levels,we will discuss about the right treatement.
