Hi... Diabetes is not that serious problem,if it can be kept under control... The problem only occurs if the sugars very high and are uncontrolled... Family support is very much essential... Do not be scared to break the news to your parents.. Get your blood sugars and kidney function test done... Start of the treatment early, in the form of diet, exercise to reduced weight and meications if needed... It is better to get all this done with the support of your family... Do not delay in doing that. The earlier you do this, you san avoid unnecessary complications and the need for hospitalisation too..
