Afrezza Units & Insulin:Carb Ratios

This video explains why insulin:carb ratios don’t work with Afrezza, no matter how hard you try.

Afrezza works so differently to previous diabetes treatments, and yet there is nothing in the box explaining how or why. It works so differently that for a while I wondered if I had a bad batch.

This video explains why the labelling on the box is unhelpful and confusing. The units just can’t be compared, and it takes a while to work out that Afrezza has two independent effects.

The first phase begins immediately but it doesn’t lower blood glucose, instead it temporarily stops it rising. This effect seems to be responsible for all the weird and wonderful properties of Afrezza, the first phase does not happen with previous insulins.

The second phase, however, works like a small dose of injectable insulin. It lowers blood glucose, and takes longer to start working. This is the only phase of Humalog or Apidra.

Previous treatments work by flooding the body with an unnaturally high level of insulin for hours, in order to slowly lower high blood glucose levels. Afrezza stops blood glucose rising in the first place using the natural first phase signal to the liver instead. This means that for the first time much lower, more natural levels of insulin can now be used in Type 1 diabetics.
