raised BGL when waking up!

[leafkicker]

I can eat lemon merangue pie or apple pie with ice cream and after 1/2 hour have a BGL of only high 4's or low 5's. This is much the same for any really sugary foods but when I wake up in the morning after 8 hours of no food, I can get a reading of low 7's even if it was only high 5's or very low 6's before I went to bed, how can this be and what does it signify? My cholesterol levels are good less than 5 for total, LDL 2 on no medication. My blood pressure is generally around the 140/80 and at times lower. My weight is 81 kg for 1,78m height which is about OK. I am physically fit. I have never had any of the typical symptoms i.e. thirst, peeing at night, etc. So, do I have diabetes type 2, IFG or what?

.DAWN ⁠PHENOMENON⁠
Everyone, diabetic or not, exhibits some Dawn ⁠Phenomenon⁠. It is a natural part of our bodies' circadian rhythms. Some have said it is the way our ancestors had the strength to rise and slay a wooly behemoth for breakfast.

Since most of us fast while sleeping, with teenagers a possible exception, our bodies use stored energy during sleep. The body uses all three macro-nutrients (carbohydrates, proteins, and fats) to store energy.

The most easily used is the storage medium of carbohydrates, called glycogen. Glycogen is made from glucose, and is stored in the liver and muscles. Since it is basically nothing more than a complex matrix of glucose, it is easy for the body to store and use, something the body does all day long. The technical term for the act of creating and storing glycogen is glycogenesis. When the body calls for the conversion of glycogen back to glucose it is called glycogenolysis.

Another macro-nutrient that is available to be converted to glucose is protein. Most of us think of our protein as being stored in muscle, but the body has protective mechanisms to make muscle wasting its last choice. One of the most useful and readily available sources of protein storage is in blood components, i.e., albumin (plasma). The body uses a process performed in the liver to convert amino acids, the building blocks of proteins, into glucose. The name for this process is gluconeogenesis, literally "the creation of new glucose".

So, what does all this have to do with a high fasting BG? Overnight, usually between 4am and 11am, your body releases some hormones. These are Growth Hormone (GH) from the anterior pituitary gland, cortisol from the adrenal cortex, glucagon from your pancreatic alpha-cells, and epinephrine (adrenalin). These hormones cause an increase in insulin resistance, raising your BG. In addition, these hormones trigger glycogenolysis and gluconeogenesis, adding stored or new glucose to your bloodstream.

Thanks for the info on Dawn Phenomena it explains part of my question but it also raises some more questions for me. If someone not diagnosed with diabetes or impaired fasting glycemia has a BGL over 7 at sometime in the day and someone with IFG has a BGL over 7 on waking (fasting) but does not exceed 7 at any other time of the day, then what is the difference? Why is one given a title and the other person not? This is the case with me, I at times am over 7 when waking but rarely go over 7 throughout the day even when eating very sweet food. This is based on taking BGL at 1/2hr, 1hr and 2 hrs after eating. I'm just trying to get a better understanding of IFG and diabetes and if anyone can answer any of my questions it would be of great interest to me. My reason for asking for some further guidance is this: do I stop eating any sweet desserts, chocolates, etc. if my BGL does not exceed 7 at any time after eating or should the fact that a BGL above 7 at waking mean sweet foods and sweets should be avoided at all or most times?

I'm not an expert but I would imagine that IFG is the start of the road towards diabetes, and that the more you cut back on the sugar and carbs now, the healthier for longer you will stay.
