Thank you for posting a query.

Look, I think you should take this seriously. Because your age is in high risk group. It is not quite surprising to have such a blood sugar level in this age.

Now, the problem is the high blood sugar level after 2 hrs of food with a normal fasting blood sugar level. A random blood sugar level of more than 200 should be taken as a diagnostic for diabetes. But, clinical examination is mandatory.

First of all, you have to do fasting and post prandial blood sugar test from a laboratory using your venous blood. Sometimes capillary blood sugar levels become erroneous.

Besides, you have to do a HbA1C test. It is the best indicator of glycemic control. It will show glycemic control of last 3 months.

Depending upon the results, it has to be determined whether anti-hyperglycemic agents should be started or not.

You can upload the report here or can consult with an endocrinologist in person for further management.

Hope this information suffices. Let me know, if you have any more question.
