The HbA1C blood tests gives an average reading of blood sugars in the blood over a period of 12 weeks.
The red corpuscles get renewed about every 12 weeks and the sugar sticks to the blood cells. This is how the average of glucose levels is worked out.
The HbA1C test is done by sending a blood sample to the laboratory for analysis. The doctor usually requests this test to see how your sugar levels have been over the 3 months and whether you are managing to stabilise your sugar levels either with controlled food intake and when being on any medication for diabetes.
A home blood monitor will only give you a blood glucose reading of the level of sugar in your body at the time that you take do the test. And this will fluctuated throughout the day and will be different before and after you have eaten any type of foods.
High A1c is high BG (blood sugar). What raises BG... carbohydrates raise BG not just sugar ALL carbs raise BG. Whole wheat raises BG ... eat less carbs have lower BG lower BG means lower A1c.
I have family members that are on insulin injections as well as having to take tablets for Type 2 diabetes. They still have to be careful what they eat and drink.
With any infections the blood glucose goes higher.
If they are not careful and don't watch their food intake, even with insulin injections and tablets, the blood glucose can still be too high.
Don't be scared of insulin. The injections are virtually painless (the needles are very thin). The great thing about insulin is that with it you absolutely can control your blood sugar.
Most people with type 2 who are put on insulin end up wishing they were on it sooner, as it is so helpful at normalizing blood sugar.
Learn all you can about diabetes and blood sugar control. Some good books are:
Diabetes Solutions - Dr. Richard Bernstein
Think Like a Pancreas
Using Insulin - John Walsh
The hospital doctor may change your medication first before putting you on insulin, so don't panic. Even if you do have to go on insulin injections, I am sure that you will be fine and will soon get the hang of it.
I trust that you are careful what you eat and drink, have smaller portions and regularly exercise. Eating small portions every 2 or 3 hours is better than having 3 large meals. If your doctor has not referred you to a diabetic dietician, ask for a referral. Going on insulin injections will not control your sugar levels if you are not careful with your food intake. Even on insulin injections you still need to be careful what you eat and drink.
Exercise will help to burn the energy and can be anything that suits you. Walking twice a day is fine. If you don't do that, you can start slowly with a short duration of time and build up the speed and the duration.
Doing any form of exercise, will help to use up the glucose in your system. After all, it is a source of energy.
Best wishes.
