Unfortunately, my friend, it's not so easy to tell, and this is because you've tested your blood glucose level too soon. Unless you are pregnant or a newly diagnosed diabetic that has been advised by your doctor or certified diabetes educator to check how various foods raise your blood glucose level, you should test after two hours.
Normally, a non-diabetic's blood glucose level will not rise above 140 mg/dL. I say normally as there are occasions when it may do, such as if you have an underlying infection, you are going through a period of extreme stress, or you are taking certain medications which are known to raise blood glucose levels. (These medications often include steroids, such as those that may be prescribed for the treatment of asthma, or for treatment of certain infections.)
You do have a few things that predispose you to developing diabetes, my friend, so you need to bear that in mind. i.e. the frequency with which you find you're needing to use the toilet; being overweight ... particularly if you have an excess of abdominal fat; the genes that you've inherited from your father; and, if where you asked your question ... Yahoo! Answers India ... is any indication of your ethnicity, then being Asian also carries a risk for the development of type 2 diabetes mellitus.
A blood glucose level of 181 mg/dL is not immediately dangerous, meaning you're not going to drop down dead or enter a comatose state, but anything above 'normal' levels does damage to your organs, your blood vessels, and your nerves.
