Any DNA test.. Ancestry, 123&Me, etc. will contain information about your health. You can go with the health option on those sites, which cost more, or go to sites on the internet that offer you free health info like My DNA Portal.com.
And both Type 1 and 2 are DNA driven. I’m a Type 2 diabetic... I am very healthy and was never a big sugar or butter person, and I’ve never been overweight yet I got Type 2... And a DNA test told me that I was prone to it, even before I was diagnosed. My father had Type 2 and my brother is a Type 1 diabetic.
Sometimes you’re just cursed by your DNA... Just because it says you’re prone doesn’t mean that you will get it... But if you do, there’s nothing else to blame. I’m also prone to hemochromatosis (a disease that causes your body to retain too much Iron), but so far I have no signs of that disease.
