Fasting, and After Every Meal
Reviewed by CDE Mehandi Sharma · Updated
GDM usually means daily blood glucose testing, and the schedule is more demanding than most people expect before they start.
The common pattern is a fasting check first thing in the morning, then one check after each main meal — four or five readings a day in total. Your own schedule should come from your care team, because it depends on your readings and your treatment.
Each reading has a job. The fasting number tells you about the overnight hours and your baseline. The after-meal numbers tell you what that specific meal did, which is the information you can actually act on.
Fitting this around an Indian household takes a little planning. Set phone alarms for one or two hours after your usual meal times rather than trying to remember. Keep the meter where you eat, not in a bedroom drawer. And if meals in your house happen at unpredictable times, that itself is worth mentioning at your appointment.
Write the readings down with a note of what you ate. A number on its own tells your doctor very little; a number with the meal beside it lets them tell you exactly what to change.
This is temporary. The testing ends with the pregnancy, and there is a clear reason for every one of those pricks in the meantime.
