Higher morning blood sugars

[ Edited ]

I had my yearly physical today.My FBS was 150 & my A1c was 6.3. I asked the doc why my morning blood sugars are high but the rest of the day they are fine.However,they are high every morning. He said it is a action of cortisol being released by the adrenal gland in the night and not to worry about it as long as they are normal thru the day .He also said that current research is finding that it's most damaging to your organs when you have large blood sugar swings. Since mine stay between 125 and 140 thru the day generally and only go up to 150 at night and my A1c is good on just metformin 500mg he is happy with things as they are.Didn't change anything, didn't scold me about anything. My cholesterol is always low - good genes - I'm lucky that way.

My morning blood sugar is also night.  Late one night I took my bs and it was about 100; then in the morning it was 170.  It's called the "dawn" effect.

Re: Higher morning blood sugars

Your blood sugar drops in the night which causes your body to release cortisol which then causes you to release stored glucose.

Re: Higher morning blood sugars

OK, I was just diagnosed with Type 2.  If the numbers are high in the morning then why wouldn't you want to take the blood sugar later on in the morning or early afternoon?  I'm sorry, my doctor didn't explain anything to me except to say only have 48 gm of carbs in a meal.  Then he gave me some sheets on Diabetes and a book.  I have an appointment at the hospital on Monday to start taking classes wih a dietitian.  AND, my lovely Humana insurance company still hasn't sent me my Glucose monitor that you stick your finger with.  He also didn't give me any medication yet (like Metformin) because I have high blood pressure and he is adjusting that medication AGAIN.  I suppose I will get more info when I go to the hospital for the class.  I would be thankful for any information from any of you.  I'm not scared and am not watching real closely about my food yet, but I do want to follow a good diet and I didn't realize that eating carbs was as important as sugars.

@luvmybeetle  Fasting blood sugars are taken in the mornings before you eat. Once you eat they are no longer "fasting".  Post eating blood sugars are expected to be higher than fasting blood sugars.

Re: Higher morning blood sugars

My DH has the same problem.  I asked about this on the diabetes thread and @Trinity11 told me to research dawn phenomenan which I did. 

 

My DH's readings can be perfectly normal when he tests before bed and then his FBS is never below 114 in the morning.  He just had his first appointment with an endocrinologist today.  Prior he's been treating with his PCP and we felt he needed a specialist.

 

The endo. suggested eating a snack before bedtime or possibly even getting up in the middle of the night and eating a snack and see if that helps.

 

DH recently began exercising and sometimes that helps a FBS as well.
