Hi
@Bunty321
I second the suggestions by
@Robo42 and by
@LaoDan -- definitely get a meter to see how you react to different types of food.
It's also a very good idea to cut out sugary foods (as your nurse suggested), but any other type of carbohydrate will also turn into sugar once ingested as you will see once you start measuring your blood glucose. (So, it's also helpful to eliminate any kind of starchy food from your diet including bread, cereal, rice, potatoes, pasta, etc.). Btw, no need to stop having fat as it does not affect blood sugar levels (so butter, cheese, bacon, etc.) is fine.
Most of us begin with testing right before a meal and two hours after the first bite. The rise in blood glucose should be no more than 2 mmol.
Good luck on your journey. Very, very many of us have been able to get back to normal or near-normal blood glucose levels without having to take medication just by testing blood sugars and adjusting what we eat. So, there is very good chance it might work for you too.
