Hi - basically it depends on what your local NHS is prepared to pay for. As CGMs (and blood monitoring generally) are still not thought (officially, via the NICE guidelines) to be an absolute requirement for T2 management, it's unlikely that they would pay for them. This is (part of) what the current NICE guidelines say:
Continuous glucose monitoring
1.6.17
Offer intermittently scanned
continuous glucose monitoring (isCGM, commonly referred to as 'flash') to adults with type 2 diabetes on
multiple daily insulin injections if any of the following apply:
- they have recurrent hypoglycaemia or severe hypoglycaemia
- they have impaired hypoglycaemia awareness
- they have a condition or disability (including a learning disability or cognitive impairment) that means they cannot self-monitor their blood glucose by capillary blood glucose monitoring but could use an isCGM device (or have it scanned for them)
- they would otherwise be advised to self-measure at least 8 times a day.
The full guidelines are here:
Your argument would need to demonstrate that you fall into one of the above categories - from what you say you might be able to convince them of the "recurrent hypoglycaemia" one.
