Hi and welcome to the forum sailerDel. Prediabetes means your blood sugars are higher than they should be, but they are not high enough for you to be diagnosed as diabetic. You would very likely have had a HbA1c blood test. This test shows the average blood glucose (sugar) over the past 3 months, although it is weighted towards the last month. Diet is the main culprit for raising your blood sugars, lack of exercise is an aggravating factor as you are not burning as much energy (sugar). Stress is another aggravating factor. Stress raises blood sugars in most instances.
As we get older our bodies tend to be less efficient at utilizing insulin. Insulin is a hormone that is produced in the pancreas. Insulin acts as a key to allow glucose into our cells for energy. This inefficiency to utilize insulin properly is called insulin resistance. The level of insulin resistance varies in people. The vast majority of type2 diabetics, if not all, have developed insulin resistance. None diabetics may also develop insulin resistance. The pancreas has to produce a lot more insulin to counter this resistance to insulin thereby allowing our muscles to use the blood sugars. If you can’t use your blood sugars effectively blood sugar sits in your blood stream, increasing the amount of sugar floating in your blood. This is what the HbA1c test measures over a three month period. IR is a common thing. Your pancreas, however, is not able to produce enough insulin to counter this insulin resistance and the carbs you are consuming. Where as a none diabetic’s pancreas can.
The best way is bring your blood sugars down is reduce one of the two things that are affecting your blood sugars, either the insulin resistance or the carbs you are eating. As it’s much Harder to bring your insulin resistance down than reducing your carbs, reducing your carbs is the best course of action to bring your blood sugars down. And those scones and cakes you are making are rammed with carbs.
It is advisable to know what your blood sugars are, so I would get myself a glucose monitor from the Chemist. They will show you how to use it. The monitor will give you a snap shot of what your blood sugars are in that moment. Unlike the HbA1c test which gives you the average blood sugars over three months.
To effectively use these glucose monitors, we tend to finger prick at the start of a meal, and then two hours after. If the second reading is within 2 mmol/ls of the first reading your body has dealt with your meal effectively. Glucose monitors are a window into the level of sugars that is in your blood at the time of reading.
