What's the latest news on Diabetes Mellitus Type 2? When do you subject your kids for testing for diabetes?

At age 40, i suffered from blurred vision and since this condition is very dangerous (i commute to and from work every day). I went to a doctor and was made to undergo test. It's at this point when i was told that i am a diabetic. It has been 3 years and taking medications has been a part of my daily routine since then. I have been very good in following my doctor but i wish to gain more updates on my ailment. I also hope there is someone who can advise on the chance of my kids inheriting diabetes (i have two kids – boys 12 and 7 y/o)
