Good DayHope All Are WellI Would Like To Know Why My Sugar Levels Go High When I Dont Eat.

A DiabetesTeam Member asked a question 💭
Johannesburg, ZA

I have been trying to fast and every morning after waking up, my sugar is 6.5 or 6.7. I thought my sugar will go down if i dont have a snack the night before, but it goes up and when i have the snack, my sugar is 5.5 or 5.7 in the morning. I have No sugar, on no medications, very low carbs.

Hi. I experienced the same thing. A lot of people on this site find their fbg to be frustrating and contrary. There may be different reasons for it though. I suspect that my fatty liver has something to do with mine-but not sure. I do know that I just finally began to get fbg under 100's. And this appears to be a result of my losing weight and lowering my carbs and fats (and sodium) over the past year (also fasting for 16 hours did the trick for me). I am unsure of the direct relationship between glucose numbers and the fasting blood glucose though, other than that fbg under 100 is "normal" and the other guidelines for glucose during the day. I was prediabetic with metabolic syndrome, no meds for diabetes, reduce calories and carbs.

Hi @A DiabetesTeam Member,
Type 1 is an autoimmune disease.

With type 1 your body thinks that the isles of langerhans, the parts of the pancreas that produce insulin, are foreign invaders, and destroys them.

Since a type 1 produces no insulin and we need insulin to live, a type 1 will die without insulin. Insulin allows the body to process food into energy.

Of course it is a complex issue. But when the body has no energy it will cease to function. Organs will fail. Since the brain needs energy ans always draws it, the brain will die.

That is the long and short of it.

They are still great numbers @ShaminShzen.
Any morning fasting blood glucose numbers below 7.0(126) are great numbers.

To address your concerns.
Every morning our livers dump glucogen which converts to glucose to aid in waking.

The liver keeps dumping glucogen stores until we shut off the taps, breaking our overnight fast by eating breakfast. Breakfast should be eaten within 30 minutes of waking.

In a nondiabetic, their body can use the insulin that is produced naturally in response to high blood glucose to maintain a normal waking blood glucose number.

But our bodies are broken and can't use, or even produce enough insulin to get normal numbers.

My morning numbers usually run between 6.1(110) and 6.6(119). I am content with these numbers. Of course I would like lower nondiabetic numbers, but these are still great numbers. My A1C is 5.1.

Sometimes when you don't eat your liver will release stored glucose. A small snack before bed can keep your sugars up enough that it doesn't happpen.

@A DiabetesTeam Member I would suggest that doing so is a byproduct of the way the various types of diabetes are now being described "clinically" while traditionally diabetes was initially (3000 years ago) as a known but singular disease

Then even at the time of the introduction of insulin, barely 100 years ago there was simply "juvenile or sugar diabetes" - if it presented in children it was "juvenile" regardless of what the actual type by todays classifications were (a child still could have had Type 2 or Mody which "presents" without the benefit of anti-body tests to confirm, exactly the same way

(The GAD or GADA test that actually confirms Type 1 or LADA was only invented in 1992 - prior to that they could test for insulin production levels, but until the GADA test there was no 100% certainty)

Today we have a variety of blood sugar, anti-body, insulin or c-peptide tests or genetic tests that confirm Type 1, LADA, MODY, or Type 2

But essentially, as soon as the diagnosis is made it is weight control, diet and exercise that have the greatest effect on blood sugar control and the amount of medication you will need to maintain control - with all the complications being shared although the different types of diabetes do see individually higher incidence rates compared to each other
