My dad (age 60) is diabetic for 12 years.
His
sugar level is not controlled. his fasting sugar was 321, After that he got some change in meal plan which result decline in sugar and now it's 222 at fasting.
It's not reducing anymore.
He is on medication , taking Glimy M2.
He is not on insulin injection.
Can he start insulin since blood sugar is not controlled ?
What tests he needs to be done to get correct dose of insulin ?
