So if your going to respond like that you need to explain your reasoning
Up until the age of 28 yrs I lived a perfectly normal (ish ) life with no medical problems. Then I started losing weight, eyesight problems, infections, extreme thirst, extreme urinating. A visit to the GP and test confirmed that I was no longer producing sufficient insulin to keep me alive. At this point I was diagnosed as type 1 diabetic. Type 1 diabetes is an autoimmune condition where the body attacks and kills parts of itself. In this case my body was attacking my pancreas. Eventually I could no longer produce insulin and had to start injecting artificial insulin. All this happened at age 28 and not at birth.
If I had been diagnosed as type 2 that would have been a totally different scenario, type 2’s produce insulin, sometimes too much. Type 2 isn’t autoimmune. I’m not going to quote to much about type 2 on account it isn’t my area of expertise.
Very , very few type 1’s are born with the condition. A lot become type 1 early in life and contrary to popular belief even more are diagnosed later in life.
Hopefully this goes some way to clearing things up.
