i had that once was urinary infection. any infection can also cause high blood sugar.
Please test at 1 1/2 - 2 hours after starting to eat. That will give us a better idea. Please also test fasting, if you can.
At 4 hours after eating your blood sugar should be back to fasting levels (ie. < 95), so your numbers are a little high. However, 1 test alone cannot draw firm conclusions.
Recommend you go to your Dr. and request Hba1c test, after explaining your symptoms.
If you are expecting some possible blood sugar issues, it is very important to eat low carb (after all diabetes is a problem with carb metabolism), and to exercise regularly, ideally every day.
119 is a litle on the high side, are you on any steroids? some drugs can rise BG.
Yes see an MD and sk for a OGTT its a test to see your responce to crabohydrates.
I used a friend's finger prick test kit, and after 4 hours from eating it was 119. Is that normal?
