Hello
@Billyboy12 and welcome to the forum.
If the 53 is your HbA1c level then you are not far into the diabetes range. For comparison, my first test was 91.
It indicates that your blood glucose levels have been a bit higher than the normal range, but probably not drastically so.
The basic cause is the levels of glucose in your blood, and for an ordinary uncomplicated type 2 like me, all that I needed to do was stop eating high carb foods, particularly the 'healthy' ones I'd been pressured to eat for a long time.
It might seem crazy, taking into account all the advice on what to eat, but my shopping lists include any meat, fish, cheese, eggs and full fat dairy, with low carb veges, salad and berries.
We need protein and fat - they are essential foods, whilst carbs give colour, texture, flavour and variety.
As you are not 'a bad diabetic' as I was described at diagnosis you might well be able to reverse things just by making a few changes, or cutting down on the higher carb foods, though I found that I actually prefer the lower carb options as I am never hungry when eating them, but feel more energised.
Tonight, for instance, I will be sharing one of Lidl's 16oz steaks with my husband, and I'll have mushrooms with mine. Himself will most likely have chips and peas.
