Yes---b/c there are 2 types, Type 1 (the type that is genetic) and Type 2 (the kind ppl get from being overweight).
So, if you are normal weight, you could have Type 1. If you are overweight, you may have developed Type 2.
Only a blood test can tell. If you have Type 2, it is usually controlled/cured with losing weight and change of diet.
If you have Type 1, there are good treatments---no cure, but proper treaments can mean a good, long, healthy life
Make an appt, with your dr.
