I can only speak for myself, but I am a type 1 diabetic and the issue for me hasn't been making progress but rather keeping the progress. I am not sure if it is related to the disease (I suspect it is considering everyone type 1 that I have known have had lightening fast metabolisms) but I require ALOT of calories to grow but when I do as long as I keep up with my eating I will make a ton of progress fast.
However if I fall off the eating wagon even for a week it puts me in a deficit that is hard to get out of without having to basically spend my entire days eating my way back up so to speak. On average it takes me 4600- 4800 calories to grow, but when I stop eating it takes up to 5000+ to get back up to a healthy weight for me.
The only thing to be aware of is when you start pushing it too far either diet wise, training wise, or stress level wise and you notice you need higher doses of insulin to maintain healthy blood sugar levels for the same number of carbs that you are eating. For me it means I am becoming resistant and usually when this happens the weight I am gaining usually turns out to be more fat than muscle. It's not the end of the world, I usually just drop the carb levels down some and figure out what needs to be fixed.
Keep in mind I have been a diabetic for 14 years at this point, so I am more dry on my own insulin production levels, so none of this may apply to you. It may never apply to you. But in case any of it did I hope it helps!
Diabetes and lifting can make you want to pull your hair out sometimes, but be patient, put your head down and grind and you should be just fine!
