Hello
@Kathleen68
Welcome to the forum.
Sorry to hear that your steroids have raised BG enough to put you into the T2 zone. An HbA1c of 48 is usually the cut-off for a diagnosis with diabetes, but we have members who were diagnosed in the 100s, so you are only just over the threshold.
Steroids certainly have a reputation for raising blood glucose, ans sometimes this is sufficient to cause a diagnosis of T2 to be made. The most immediate and effective thing you can do is to act on the other major modifiable cause of elevated blood glucose - the food you eat.
While there are obvious things like cakes, biscuits, sweets and sugary drinks that you will be wanting to cut out straight away, you might be surprised how much *all* carbohydrate affects your BG levels, including rice, pasta, bread, pastry, grains, cereals and many fruits. It can be very helpful to keep a food diary of all meals and snacks, and to squint at the back of packets and get your kitchen scales out to add up or estimate how much carbohydrate is in what your are eating - it’s the total carbohydrate figure you need, rather than ‘of which sugars’ since all carbohydrate will be broken down to glucose in the blood. This will allow you to see where the main sources of carbs are in your current diet, and may help you to see which meals could do with a tweak to reduce the carb load.
Adding some daily or regular exercise and activity into your week is another very helpful strategy. It doesn’t have to be marathon running, but just something that raises your heart rate for around 30 minutes a day.
It’s best to make changes to your menu (and activity levels) gradually - partly because they need to be sustainable long term, but also because very rapid and sudden changes to blood glucose levels are harder on the fine blood vessels, and changing things more gently will give your body time to adapt.
Good luck, and let us know how you get on.
