Thanks for writing to us.
you are 30 weeks pregnant and now your sugar levels are derranged, this condition is known as gestational diabetes
The first and foremost important thing in these cases is properly planned diet. You have to follow a proper diet routine.
Many pregnant ladies with gestational diabetes are controlled with diet alone.
After following proper dietary advice, repeat your blood sugars after 3 days, if still high, you will need to start on insulin
If sugars levels are normal after diet control, do check the levels after 1 week as with advancing gestation the physiology keeps on changing.
