Thanks for query did you check years fasting value. If years fasting value is high and a difference in fasting and post-meal is up to 70 in that case correction of fasting is the first priority.
If fasting is within targets like 100 around and posts meal is high means difference is high then
you need to check the diet
of that meal
if carbs more than reduce carb.
And can start voglibose
but one reading never decides the treatment.
2 hr after a major meal
make a chart
for 15 days. Share to me. You can connect to me with all years reports and sugar
