Hi
@poppy659 do you test your blood glucose?
I ask because that is a fair amount if weight to lose if you don't need to and weight loss us a symptom of Type 1 diabetes.
If your blood glucose is high despite your diet change, I recommend visiting your GP.
And if you start experiencing breathing problems along with stomach pain, get to a&e as these are symptoms of DKA.
Sorry, I don't mean to scare you but too many adults diagnosed with Type 1 are initially misdiagnosed with type 2 by ignorant doctors who think you are too old.
