Hi, I am LADA and was experiencing similar issue to you after initial diagnosis (fast drops after post-meal highs with no bolus insulin having been taken for meal).
My endo gave me this explanation: first phase insulin is the first to die-- the post-meal high is because your first phase insulin cannot cover. When you go high like that the remaining, undead second phase insulin overcompensates to then drive you low. In other words, you must not allow the post-meal high and then you won’t get the reactive hypo.
I was able to blunt this hi-low post-meal experience in the following ways:
- Very low carb meals that don’t typically cause a spike;
- Making sure to eat protein or fiber at meal outset to slow digestion of any carb intake;
- definitely not eating carbs on empty stomach;
- and/or using fast acting insulin (I use both humalog and afrezza based on circumstances/meal/etc) to stop any post-meal high from occurring, hence eliminating the reactive hypo.
Things that helped me through honeymoon phase with bolus insulin:
a) Using a Jr. pen with 1/2 unit dosing increments; and
b) Splitting afrezza cartridges in half.
Hope this is helpful!
