Answers: yes, it has be proven that your chances of getting any type of diabetes increases when you have a kith and kin history of it. If it doesn't run in your relations, yes, you can still get it, diabetes is not JUST genetic.
You can be any age to carry diabetic symptoms. Type 2 is very irregular in relatives under the age of 20, and it is also undercooked in those not overweight. Most those who are diagnosed with Type 1 are diagnosed beforehand the age of 20. Unlike type 2, weight and over adjectives health come across to have nil to do with getting type 1.
YES is is genetic. Chances are if you mother, father, grandmothers, grandfathers, etc. have diabetes you have a superior risk. In some cases, as with my husband, his kinfolk members have diabetes, and he now have it, but it is what some people refer to as "age" diabetes, as he is immediately 60 and it has merely shown up. We have friends who this have happened to also. Just survey your diet and get your blood work.
