10, 20, 30 Minutes Walking to Lower Highs

Simple explanation

This explorer estimates how much glucose may fall during moderate activity when rapid-acting insulin is still active in the body. You enter body weight, activity date and start time, current glucose, glucose trend, activity type, and recent bolus insulin doses.

Practical interpretation

The more active rapid-acting insulin present at the start of activity, the larger the expected glucose-lowering effect. Trend is applied as a final modifier: falling trends increase the estimate and rising trends reduce it.

Detailed explanation

Each bolus is converted into units per kilogram (U/kg). Anchor points:

• 0.05 U/kg → peak about 1 hour, tail about 4 hours
• 0.10 U/kg → peak about 1.5 hours, tail about 6 hours
• 0.20 U/kg → peak about 2 hours, tail about 7 hours
• 0.30 U/kg → peak about 2.5 hours, tail about 8 hours

Glucose lowering scales from 0.025 mmol/L per minute at 0 U/kg to 0.20 mmol/L per minute at 0.14 U/kg or above. Trend modifier: Falling fast +30%, Falling +15%, Stable 0%, Rising −15%, Rising fast −30%.
