The main diabetes causes are not all known yet there are evidences that indicate that it has a genetic disposition to it. This means that whether you will have diabetes or not is determined by your gene.Another known diabetes cause is obesity. This is the most common type-2 diabetes cause in children, adolescents and young adults.
Sedentary life style also another diabetes cause. It influences the onset of diabetes a great deal. In a study involving diabetic school children, it was observed that during school days, they tend to need diabetic drugs like insulin but when there was break or holiday, they needed their drugs less and sometimes seemed to be able to do without them. The reason is not far fetched, children are more active during breaks and holidays than on school days when they sit in class and learn.
