Is diabetes curable and does it run in families?

Diabetes is controllable, but not curable.

Some risk factors for diabetes are genetic, but no genetic factors can cause diabetes alone.

Insulin dependent, or Type I diabetes is caused by an autoimmune condition in which the pancreas cells are destroyed to the point where they cannot produce enough insulin. This condition is currently incurable and must be treated with insulin supplementation.


In many cases non-insulin dependent (Type II) diabetes is curable with only lifestyles changes. Type II is caused by the decreased sensitivity of cells to insulin.


Fortunately, insulin sensitivity has been shown to be drastically increased by:

  • Physical Activity
  • Caloric Restriction
  • Ketogenic diet (low calorie and/or low carbohydrate)
  • Adequate sleep and low stress lifestyle


The predisposition for diabetes does run in families. Some types of insulin resistance may be purely genetic but this is not at all common.


The best prevention for diabetes is having controlled blood sugar levels, being physically active and maintaining a healthy weight.
