Increasing diabetes. Alarming for me.

My father is suffering from diabetes from 2009.From that particular year he is constantly going for morning walks.As we know that starch intake must be reduced and my father always tried to do it but at times he would take a lot of food containg starch like water rice,2 times a day.But for the past 2 years he had maintained his diet and his morning walks.He had consulted a lot physicians.But his diabetes is constantly increasing.He has been using insulin injections. But even then it is not under control.2 months earlier me and him went to Kanungo Institute of Diabetes in Bhubaneshwar,odisha.He gave some medicines.I personally know the name of the medicine that is Absolute 3g.I think the medicines are not responding.Today I got to know that his diabetes has reached 342.I am really nervous.Please it's my kind and humble request to show me some way so that I can help my father by taking him to a concerned physician.I am a +2 student.This is very alarming for me.
