Hello doctor,

Last night I ate a cheese pizza and a chocolate bar. Eight hours later (after fasting) I tested my blood sugar and it came out at 128, and 30 minutes later it dropped to 106, and 15 minutes later it raised to 109 (without eating and drinking anything). My question is, do I have diabetes or did I initially have high sugar because I ate pizza very late at night?

Hello,

Welcome to icliniq.com.

Usually fasting blood glucose is 126 mg and above is considered as diagnostic for diabetes. However, it is also possible that because of the dinner, fasting glucose might have shown a higher level. So to confirm whether there is diabetes or not, you may have to get a PP (postprandial) glucose level and HbA1c %. If PP is 200 mg and above and HbA1c % 6.5 % and above, then diabetes is considered to confirm. Looking at your weight and height, another important fact is with a BMI of 42.92 kgs/Sq meter you are already in grade 3 obesity. With a significant amount of excess weight. This itself is an invitation for getting diabetes.
