Getting a bit stuck on finding data for the probability of death from type 1 diabetes. Hypothetical base case is 20 year old with no diabetic complications. Maybe I'm not looking in the right places!
Insulin replacement therapy isn't as effective as naturally-produced insulin, however. People with type 1 diabetes often have blood sugar levels that are too high or too low, because it's difficult to predict exactly how much insulin you'll need. When blood sugar levels are too high due to too little insulin, it causes damage that can lead to long term complications, such as an increased risk of kidney failure and heart disease. On the other hand, if you have too much insulin, blood sugar levels can drop dangerously low, potentially leading to coma or death.
