Hi Very strict and early sugar management in diabetic will help in progression of the diabetes and prevention or delay of development of diabetes related complications like kidney disease, eye disease , heart problems etc. Glycemic control is achieved with dietary modifications and drugs (including anti diabetic drugs and insulin) This glycemic control is monitored by fasting and 2hr after breakfast and HbA1C monitoring. In type 2 diabetes, initially if glucose not controlled with medical nutritional therapy, a single drug ( usually metformin) is started. If not achieved goal, as in your case a second drug to be added and step by step other drugs depending on sugar level and sometimes insulin may become mandatory. So consult a doctor for opinion regarding next step of therapy Meanwhile you check and modify your dietary habits if possible Thank you...
