Sorry to hear about your diabetes diagnosis, and your anaemia and other health problems
Hopefully your Dr is using fructosamine or another test which doesn’t involve red blood cells to monitor your overall progress with diabetes, because as
@rebrascora says, amaemia can adversely affect the accuracy of the standard HbA1c.
Eating well with diabetes and being vegetarian is perfectly possible, but you may need to adjust and adapt some recipes, because while meat as a protein source contains no carbohydrate, other protein sources (eg pulses) can also be a source of carbohydrates. Additionally some recipes might use things like adding breadcrumbs for texture or ‘filler’ - like they do with the rusk added to cheaper meat sausages.
And it is the total carbohydrate content (not just ‘of which sugars‘) that you need to balance with both your meds, and your body’s ability to cope with different carb sources - as a sort of triangular balancing act!
Keeping a food diary, along with a reasonable estimate of the total carbohydrate content of different meals and snacks can be really helpful. Then you can spot the ‘big hitters’ and begin to experiment with some tweaks and changes. Eg if you had porridge or muesli for breakfast, you might be able to halve the carb count or more by basing the breakfast on unsweetened greek yoghurt with some frozen berries, and then a sprinkling of granola / nuts / seeds for texture.
As you are on injectable meds, it is wise to make any changes to your menu gradually and incrementally. Do you have a BG meter to monitor your levels at home?
Sounds like the arthritis and the extra weight you are carrying might make activity slightly challenging for you, but it will really help if you can try to increase the amount of gentle exercise and activity you are able to put into your routine too. Doesn’t have to be hugely strenuous, but just raising your heart rate for 30 minutes.
Best of luck and let us know how you get on
