Had late night snacks of fries and chips at 2 am my blood sugar next morning at 7.30 am is 165 should i be worried?had it tested for the first time?

It's not prudent to draw conclusions from an isolated, nonfasting blood sugar under the circumstances you describe. Talk to a medical provider about diabetic screening. They'll want to look at your hemoglobin A-1C, a glucose tolerance test, lipid studies, and other important health indicators. If you're looking for stuff to worry about, diabetes isn't the only lurking threat out there.

You should see your doctor for arranging a fasting plasma glucose level at an accredited laboratory and A1c test for a proper evaluation.
