Putting insulin in an IV is how it is done in hospitals for patients who are very ill.
It does work faster and they also put a cgm in a vein to get super fast accurate glucose readings.
Unfortunately it’s too much to expect an average patient to be able to do that not to mention the complications and risk involved.
I also don’t know the effect of continuous insulin on the vein you are injecting. We already know how insulin and glucose cause damage to blood vessels. If one, say your portal vein was always used it might cause accelerated damage.
The original implanted insulin pumps of the 80s, which have been abandoned had a catheter into the duodenum, it used concentrated REGULAR insulin with faster effects than subcutaneous injections of log insulin’s.
I agree… and I also think that (based on my experience with afrezza) that with regular human insulin the amount injected would be tremendously forgiving… that seems to me to be how it must work in the hospital… since they’re dumping strait regular insulin directly into the blood stream with little regard for the patients insulin/ carb ratios/ total daily dose/ basal rates etc etc all the stuff that we have to become tremendously knowledgeable and aware of all day every day in order to use insulin subcutaneously… seems clear to me that we’re talking about a different absorbtion mechanism and disposal of excess mechanism when regular is loaded directly into bloodstream
