Fasting bg this morning (lab test) was 6.25 one hour after usual mixed insulin dose, no breakfast and walked a bit to the lab. I usually test 2 hours after the main meal of the day because dinner is within my powers, the rest of the day depends on liver and cellular metabolism. Being on insulin and sometimes experiencing hypo during the night, I suppose fasting 6.25 in the morning was caused by Somogyi effect. Everything else is normal: HbA1c today 4.3 % (24 mmol/mol). Average glucose 4.3. What`s your experience with Somogyi effect, if any ? How long does it last (checked bg at noon it was even higher 7.3) ? As I said, I usually test 2 hours after dinner. Thank you.
