'''Blood glucose''' is the amount of sugar in your blood, measured in mg/dL. Loopa logs it inside [[Vitals tracking]] and grades each reading against the American Diabetes Association ranges, split by whether you measured fasting or after a meal.

Glucose tracking is informational only. It is not a diagnosis and not medical advice. Only a clinician can diagnose or treat diabetes. Bring these numbers to your appointments.

== Log a reading ==

On the '''Vitals''' page:

# Enter your glucose in mg/dL.
# Choose '''Fasting''' or '''Post-meal'''. The timing travels with the reading and sets which range it is graded against.
# Save.

'''Fasting''' means no food or drink other than water for at least 8 hours, usually first thing in the morning. '''Post-meal''' readings are typically taken about 2 hours after you start eating.

== What the ranges mean ==

Loopa uses the ADA thresholds.<ref>{{cite web|title=Diagnosis|url=https://diabetes.org/about-diabetes/diagnosis|website=American Diabetes Association|access-date=June 30, 2026}}</ref>

'''Fasting'''
* '''Normal''': 70 to 99 mg/dL
* '''Pre-diabetes''': 100 to 125 mg/dL
* '''High''' (diabetes range): 126 mg/dL or higher

'''Post-meal'''
* '''Normal''': under 140 mg/dL
* '''Elevated''': 140 to 199 mg/dL
* '''High''' (diabetes range): 200 mg/dL or higher

A single high reading is not a diagnosis. Diagnosis needs repeat testing and a clinician. What matters here is your pattern over time.

== A note on low readings ==

A reading below 70 mg/dL is low (hypoglycemia). If you feel shaky, sweaty, confused, or dizzy, treat it right away with fast-acting carbs and follow the plan your clinician gave you. Log the reading afterward so the pattern is captured.

== Track the trend ==

Because timing travels with each reading, the '''Trends''' card charts fasting and post-meal glucose as separate 30-day lines, each against its own range. Steady habits (same time, same conditions) make the trend far more useful than any one number.
