I really can't see how this can work well. I mean currently we inject BEFORE eating, sometimes well before, to prevent a spike. How can a patch which reacts to your peripheral blood sugar anticipate a spike? Seems crazy to me.
Blimey, generally I inject after eating. I was told back in 1984 to inject 10 minutes before eating.
I'm convinced this is dangerous as now & then insulin gets to work too quick & sugar level can plummet before any food is digested. I would only inject before if I know sugar levels are high.
If I'm out for a meal then I inject part way in to the meal as it may be up to an hour before I finish so then I agree, a spike would happen.
If you read the article it does say this patch emulates beta cells so it does sound good to me.
It would put insulin in when required basically.
Any system that could do this would almost certainly do it better than the way I've been doing it for over 31 years!
