Hi Jennys dad
You are taking insulin still I assume, just not novo and levemir? When you say 'knowingly type 1' do you just mean that it was bam, diagnosed, but you were probably (like all T1's myself included) diabetic before you were diagnosed?
Re the normal levels question - it very much depends on what you want to achieve. Most medical professionals are happy if you start off at levels between 4-7 (though I prefer to be in the 5's or under if at all possible) and then eat, take insulin and come back to where you started. Spikes in blood sugar are unfortunately a problem for T1's depending on diet - the more starchy, sugary your diet is, the more likely you are to get a spike in blood glucose at the one hour point. It may come back down when you test at the 4 hour point of whatever but there is evidence to suggest spikes in bg cause damage too. I hope you dont mind me saying, but I would never hope to be at 15mmol at ANY point in my diabetic life (illness aside which cant be helped) and certainly not at one hour. Accepted medical wisdom is under 10mmol at one hour, though most well controlled diabetics prefer to be under 8. Difficulty isthat as I said, depending on what you eat, will depend on how achievable that is.
Why do your work need to know what you are after eating, bg wise? Why do you think you will be pensioned off? Could you give us a bit more info so we could advise you. Aside from feeling absolutely rubbish ( double figures have me dizzy, fatigued, feeling generally rubbish) what impact on your job should bg have?
