thanks for using HCM
is a chronic disease and as a goal diabetics after a while should be able to make some little adjustments in the dosages of their anti-diabetic drugs based on their blood sugar level and or symptoms. Unfortunately, your husband was just recently diagnosed and put on treatment only a couple of months back; so it is likely that he cannot fully understand how his anti-diabetic regimen affects his various blood sugar levels .
What he needs is that a daily follow up of his blood sugar level should be done to better understand how his blood sugar level varies with respect to the dosage of drug he is taking and to see if the dosage has to be added or not and to rule out any contributing factor to poor blood sugar control like infection, an incorrect in take method of drugs etc. A fasting blood sugar level of 245 is high but is not as bad and alarming that should make him panic cause stress
further increases his sugar level. All he needs is a follow up with adjustment of the dosages of his drugs if necessary.
