How Do You Track Blood Sugar?
Tracking blood sugar means recording these values with each glucose check:
- Glucose reading (mg/dL from your meter)
- Reading type (fasting, pre-meal, post-meal, bedtime)
- Time (when you checked)
- Context (what you ate, exercise, medication timing)
BodySitRep's Blood Sugar tracker logs all of this and displays your readings on a chart with reference lines at 100, 126, and 200 mg/dL.
Why tracking blood sugar matters
Blood sugar fluctuates throughout the day based on food, activity, stress, and medication. A single lab test every 3 months gives your doctor one number. Daily tracking gives them dozens of readings with context, showing how your glucose responds to real life.
For people managing diabetes or pre-diabetes, this data directly influences treatment decisions. For everyone else, it reveals how food and habits affect energy, focus, and overall health.
Step-by-step tracking

- Open the Blood Sugar tracker.
- Enter the glucose reading in mg/dL.

Tips
- Always record the reading type. Fasting and post-meal numbers mean different things.
- Track Nutrition alongside glucose to see which foods spike your levels.
- Note medication timing. "Checked 2 hours after Metformin" is useful context.
- Export your glucose log before endocrinology appointments.
Frequently asked questions
When should I check my blood sugar?
Common times are fasting (first thing in the morning), before meals, and 2 hours after meals. Your doctor will tell you which readings matter most for your situation. Log the reading type each time so your data is easy to interpret.
What is a normal fasting blood sugar?
A normal fasting glucose is below 100 mg/dL. 100 to 125 mg/dL is considered pre-diabetic. 126 mg/dL or higher on two separate tests indicates diabetes. These thresholds are shown as reference lines on the BodySitRep chart.
Can I track blood sugar without diabetes?
Yes. Many people track glucose to monitor pre-diabetic conditions, understand how food affects their energy, or keep records during pregnancy. You do not need a diabetes diagnosis to benefit from glucose tracking.
How do I share my glucose log with my doctor?
Export your data as CSV from the Exports section. The file includes dates, readings, reading types, and notes. Open it in Excel or Google Sheets, or send it directly to your provider.
