Hi Daisymay, from what I have gleamed an occasional short term rise will not cause you any harm, however if this was a typical reaction to most meals, then you need to seek advice. A HBA1C test will let you know how your general blood glucose control is going. A fasting reading of 7.3 is slightly higher than recommendations, but you havent said what you ate. If you are diabetic you will get high 2 hour readings if you have consumed high carbs, that is what being diabetic is all about. To stay healthy you need to keep testing and find out what you can eat to prevent the 2 hour high readings. Best speak to your nurse.
All the best Steve
