Glucose & metabolic health glossary
The vocabulary of blood-sugar tracking, in plain language. Clear definitions you can use: no jargon, no alarm.
A
B
C
- Carb countingEstimating the carbohydrate in a meal to anticipate (or dose for) its effect on glucose.
- CarbohydrateThe macronutrient (starches and sugars) that has the largest direct effect on blood glucose.
- Continuous glucose monitor (CGM)A wearable sensor that reads glucose automatically, often every few minutes.
D
E
F
G
- GLP-1 receptor agonistA class of medications, including semaglutide and tirzepatide, that lower glucose and appetite by mimicking a gut hormone.
- GlucagonThe hormone that raises blood glucose: insulin's counterpart from the pancreas.
- Glucose variability (CV)How much your readings swing around their average, usually as a coefficient of variation.
- Glycemic index (GI)A 0–100 score for how quickly a carbohydrate food raises blood glucose, compared with pure glucose.
- Glycemic load (GL)GI adjusted for the carbohydrate in a real serving: a better guide to a food's actual impact.
- GMI (Glucose Management Indicator)An A1C-like estimate calculated from your average glucose readings rather than a blood draw.

T
- Time in range (TIR)The share of your readings that fall within your target glucose band: a modern day-to-day measure of control.
- Type 1 diabetesAn autoimmune condition in which the body stops making insulin and must replace it.
- Type 2 diabetesA condition where the body resists insulin and blood glucose stays elevated over time.
General information, not medical advice. Put these terms to work with the glycemic index of common foods, the A1C calculator, the blood sugar chart, and the AGP report tool, or read how we calculate your numbers.
Put these terms to work
Knowing what time in range or an estimated A1C means is the start. SteadyRange turns your own readings into exactly these numbers, with a calm verdict on each, on a private log you control.
