Hi,

When your son's intestines healed, he was able to absorb food better; hence
higher blood glucose levels unless he changed all his calculations to reflect
this.  My husband is T2 and on insulin and found that the increased food
absorption increased his insulin needs.  When he was at his sickest,
celiac-wise, the Drs were praising his LOW hba1cs, not realizing that he
wasn't absorbing his food.

To help get a handle on this, it may be beneficial to read Dr. Richard's
Bernstein's Diabetes Solutions.  Dr B has been T1 for over 50 yrs and uses
lower amounts of carbs to keep the numbers closer to normal at all times.
Less room for error, also.
