What triggers diabetes in people with a family history of the disease?

Once you have the design for diabetes built into your body, something needs to trigger it. Your genetics are your diabetes hardware. Your age and weight are your diabetes software. If you are set up for diabetes, it shows up when you are old enough (usually about 40) or heavy enough. If you are really skinny, you probably got your diagnosis later in life. If you are a bit hefty, you probably got your diagnosis earlier in life.
