Hello
I hope you get this answer in time. Dizziness can happen for a lot of reasons but in your case being a diabetic it can happen both due to a low or a very high blood sugar level as well. Its good that you have checked your levels already and that they are a t 211. It is high but not alarmingly high because you have eaten just an hour ago and you did take a meal high in calories and also took a sugary drink along with it. So yes your last meal could be a reason for your high sugar levels after an hour of the meal. The thing which we cannot comment on right now is that are your sugar levels still rising? you will need to check again after a few hours to keep an eye. No need to panic but try to refrain from sugary foods and eat a healthy and balanced diet meant for diabetics. Your blood pressure although slightly high is not a cause of alarm for you current dizziness. Therefore I recommend you to take a good rest, assure yourself and take your regular medications on time as advised by your personal physician. Once you are feeling fine I would like you to exercise regularly and keep yourself active in a few days time. Activity goes a long way in making you healthier and keeping your blood sugars at bay. Incase your sugar levels are to low please take something sweet or if to high and rising please visit your nearest doctor for further care. I hope this helps.
