Hi, thanks for using healthcare magic
value is high, the aim is less than 7%, some organizations put their goals even lower, at 6.5%. The value of 10 implies that control needs to be optimised.
This can be done modification of diet, physical activity and medication if necessary.
In terms of diet, you would need to reduce your carbohydrate
intake to reduce the blood sugars, the fasting of 160 implies that the meals and drinks used in the evenings may be high in carbohydrate intake. You can focus on getting the fasting readings to normal and see if this improves the HbA1c. The 3 rotis at supper may be a little too much because of the flour which is a carbohydrates, it this can be reduced and substituted with low carbohydrate vegetables/ fruit or a slight increase in the protein, it should improve the readings.
Reducing your carbohydrate intake would involve reducing your use of breads/biscuits/roti skins/pasta/rice/flour products/ some breakfast cereals/ fruit juices/sodas.
If with the dietary modifications and increase in activity, your blood sugars are still high then your doctor will consider altering your medication.
I hope this helps
