Ta the moment i shouit get blood fast test. I check my bloods now as i was too high.

What is normal average blood sugar drop over night in sleep. One night i had 7.1 having eaten cooked bramley apple nuts greek youghurt and cinnamon then next morning it went don to 5.4 before eating anything. I know you can only really learn from test and that must always be first and GP etc but is this what youd expect in a normal blood sugar pre diabletes which i am if im not diabetic now
 
Hi Ro9998 - I know you've been a member for a long time.

Everyone's blood glucose will probably slowly normally decline overnight. Many people (I'm one) find that this stops when the liver dumps a load of glucose into the bloodstream around 4 or 5am causing a BG rise. I'm going to attach a CGM graph showing this sort of thing in a person without diabetes.

You'll see from this graph there's a big drop between midnight and around 3 or 4am, when the drop levels out and starts to gradually increase.

Thank you. So even with Diabetes blood glucose goes down. I was under thought that its a sliding scale? My dad had type 1 so i thought he had to use insuline to bring blood sugar down.

My blood after 3 days 4 large mince pies 9 small was 8.5 its now with brutal diet 7.1 at night or less to 5.4 am but sustainable diet life style its all hidden i ahd other foods aptoes and depression all joining in. Do you have chart of how would loof if i am diabetic?

Yes, everyone's blood glucose varies all the time, T1, T2 or non-diabetic.

Non-diabetic people will typically see lower rises and quicker falls in blood glucose after food because their insulin system is working properly.

People who are Type 1 typically don't produce insulin of their own so need to inject insulin one way or the other. This affects their blood glucose levels.

People with type 2 like me typically have plenty of their own insulin but also have insulin resistance, which means the insulin doesn't have the effect it should. One way to deal with this is not to eat things (carbohydrates and sugars) that raise blood glucose in the first place, which is what I and many others do.

The graph I posted was as an example of one day for one non-diabetic person, to show that it's normal for blood glucose to vary over the course of a day. The following day might have been totally different. Someone else's would not have looked the same.

That works the same for T2 diabetic people. It all depends what we eat, what we do, and how our systems are working at the time. You'll find plenty of examples of CGM graphs for T2 folks on the internet - they'll not all look the same.
 
I'm convinced I'm diabetic then I test night then morning unless bread at night lasts all night. I have it thank you so next is seeing if I can get remission which is hard impossible

Remission means cells that were destroyed stay destroyed but weight diet balance correct

No, in Type 2 no cells are destroyed (in general), Type 2 remission is 'normal' Blood Glucose levels without requiring diabetes medication.
In Type 1 and Type 3 remission does not exist. Though one might say that people who have a pancreas transplant are 'cured' or in remission.

Weight is a completely separate issue to T2 diabetes, in that although the methods (ultra low calorie or Low Carb) that most T2's get better glucose control will also reduce weight (if overweight to start with) and blood pressure (if it was high to start with) - but NOT in all cases!
 
As types 2 diabetics, our problem is hyperinsulimia. Too much Insulin. Because due to Insulin resistance, our bodies can't use glucose properly, our systems pump out more Insulin to try to lower our blood sugar levels. Theoretically our pancreas can get worn out, but usually only with drugs that increase the Insulin output.
Eating a low carb diet, reduces the Glucose in our blood, which reduces the Insulin also. This allows our bodies to burn the stored fat for energy, something it cannot do with high Insulin levels, which is why weight gain is a symptom of type 2 diabetes.
Most type 2 diabetics that reach remission, actually get there before the major weight loss. It's not the overall weight loss that does it, it's the weight of fat around our internal organs.
For remission think near perfect blood sugar control, without help from drugs. It is not a cure, returning to the old ways of eating, means returning to diabetic numbers again.
Our blood sugars fluctuate constantly, non diabetics, spike and return to normal quickly, (everything is working properly).
We spike and it takes longer to return to normal (sugar regulation system is wonky). Type 1 diabetics have no endogenous Insulin, so have to inject, to survive.
You will need to see a doctor, to find out if you are pre diabetic, or diabetic, via an Hba1c test. 7.1 mmol is not a very high reading, non diabetics can also hit 11 or 12 after a meal, but drop back to 4 - 6 rapidly, as our systems are intended to do.

Wh at makes you think you have diabetes? The two figures you've given aren't in any way evidence of that.

And remission isn't impossible.
