Hi, Being diagnosed with an HbA1c of 50 is not too bad. It is a level where if left, you will experience further complications over time. But there are lots of people on here would be envious of being diagnosed at HbA1c of 50 as many are considerably higher.
You are in an excellent position to reduce this figure by following a Low Carb High Fat diet, as lots do on this forum.
Your doctor will probably direct you to the NHS diet with the 'eat well plate' and send you on a DESMOND course.
They will tell you, (as they did me) that they are happy if you can keep your figures between 43 & 53 but warn you at the same time, that it will progress.
Facts are Reduce your figures and it won't.
Stay on here, follow what we all do, and you will get that figures down considerably.
Lastly, don't panic it will all make sense eventually.
Neil
