GlucoseCurve – Meal & Insulin Education Simulator

Simulation inputs

This is an educational model, not a recommendation. Values are in mg/dL and grams of carbs.

Starting blood glucose

mg/dL

Carbohydrates in meal

g carbs

Carb type

Carb sensitivity

mg/dL per g carb

Rough estimate of how much your BG rises per gram of carbs.

Target range (for shading only)

Lower target

mg/dL

Upper target

mg/dL

Include rapid-acting insulin?

Insulin-to-carb ratio

g carbs per unit

Example: 1 unit for every 10 grams of carbs → enter 10.

Insulin sensitivity (ISF)

mg/dL per unit

How much 1 unit usually lowers your BG. Optional — see How it works.

Insulin dose (optional override)

units

Show curves for different timing:

Pre-bolus (~20 min before) At meal time Post-meal (~20 min after)
