So you tell me how my son could have avoided diabetes?.  Be born to different parents?  Pity there is absolutely no history in either family of either type 1 or 2 diabetes.  


I have no idea of the specifics of your son. However, as a general rule for the rest of the population I think it's fair to say 3 of the 4 main causes of type 2 diabetes are avoidable, and the risk of developing it can be reduced:

 

The rapid rise in the number of adults developing type 2 diabetes is due to:

  • increasing levels of obesity
  • a lack of exercise
  • increase in unhealthy diets
  • an ageing population
