Ask to be referred to a hospital consultant....they deal with diabetes 24.7. GP's as much as they may specialise in diaetes,,,don't deal with it 24/7 and are loathe because of their budgets to give out as many blood strips and other things that we need...However a consultant and DSN from hospital can write and tell gp what to do, and they have to prescribe accordingly......
If you are a type 1, I peronsally would have thought that you needed t go on to insulin straightaway, but I am not a medic trained person...so obviously could be totally wrong.
Constultants at hospitals are also more likely from my experience to get you to see the peiople that you need..and that you should be asking to see...i.e a dietitian and to start carb counting......
