Hi
@RM51 and welcome to the forum
There are 2 different things going on here, but only one that you can directly do something about, so I suggest you concentrate on that - i.e. your meals
A HbA1C level of 44 only just puts you in the pre-diabetic range, so it should only take a small change to get you back in the normal range again.
All carbohydrates when digested turn into glucose, and Type 2 diabetics are unable to handle the large amounts of carbs in the modern diet as well as the average person, so they get persistently higher blood glucose which can cause health problems.
The simplest and most direct way of fixing the problem is to reduce the amount of carbohydrates (particularly refined carbs) that we eat.
So take a BG measurement just before a meal and then 2hrs later (2 hrs after first reading, not 2hrs after finishing the meal). If the 2nd Blood glucose reading is more that 2.0 mmol higher than the 1st, then it is likely that the meal has too many carbs or too much refined carb for your body to easily handle. Thus it's a good idea to reduce the portion of carbs or substitute with something containing less carbs or less refined carbs.
If you do this a few times for each Breakfast , Lunch and Dinner you will soon know the best foods for your body and also the ones you most need to avoid. Breakfast Cereals and Fruit Juices are the ones that catch most people out at first.
The first thing in the morning ( a Fasting Blood Glucose) level Is affected by the liver. It is known as Dawn Phenomenon ( DP) or Foot On The Floor Syndrome (FOTF). You can't directly control this. Your liver thinks you are living like a cave dweller and so need extra energy to go and hunt/gather your breakfast. Once your body gets used to a lower Blood Glucose, then this DP slowly get weaker, but this can take a very long time.
Mine is still quite strong even having been in remission for over 2yrs already.
