Explain type 2 diabetes in a 12 year old. thank you ?

Diabetes & 12yo: Type 2 diabetes is caused by either low Insulin or the body is resistant to the effect of insulin, regardless of age. A common factor causing type 2 diabetes is obesity. There are also other hormone disorders associated with diabetes like cushing's. I suggest that you get professional help as untreated diabetes has severe long-term affects. You need good sugar control. Best wishes.

Same as any age: If you are sure it's type 2, then it's just like type 2 in any age: Insulin deficiency or Insulin resistance or both. The most common cause of type 2 is obesity. There are many diabetes drugs currently available that do not cause weight gain. These would be the best to use. Talk to a physician about these choices. Good luck.
