Hi Jennibambi. Welcome. How did you come to be diagnosed. Try not to panic, diabetes is a condition that can be managed well !
That 48 figure sounds like the Hb1ac blood test.
It's an average of our BG ( blood glucose) during the past 12 or so weeks.
The 48 shows you are just only over the lowest threshold for being diagnosed with diabetes. 42 to 47 is pre diabetes.
I know it's a shock and very scarey. However it sounds like you have discovered it in the early stages , which is good !! You have also found us early too , which is great as You'll get info and support from the horses mouth, us who live with it daily.
As has already been said, One of the best things you can do for yourself, is to find out which carbohydrates affect you and which don't . The only way is by self testing, tbph, unless your gp practice is very enlightened, you will be told it's not necessary to test, the Hb1ac is all that's needed etc. We think it's a cost cutting measure which in the long term is going to cost the NHS more.
If they won't provide you with one and you can afford It ,The cheapest one to self fundis the SD Codefree meter available from Amazon or directly from Homehealth. We use the mmol/l measurement in the uk, don't forget to claim VAT relief

It's the ongoing cost of the test strips you have to watch out for, meters that you can buy in chemists have testing strips that cost between £15 -£25 for 50 the Codefree ones are around £8
It's a perfectly good meter .
