About Your High Episode

Range: 150-600 mg/dL  *  Hyperglycemia threshold: 180 mg/dL

e.g. 2 = 2 hours above 250

How This Works

Recovery time is estimated based on the peak glucose reached, duration above 250 mg/dL, and the underlying cause:

Quick (2-6h): Peak <300 mg/dL AND duration <4h AND cause = dietary slip or stress AND taking insulin or combination therapy Moderate (6-24h): Peak 300-400 mg/dL OR duration 4-8h OR cause = missed medication Extended (24-72h): Peak >400 mg/dL OR duration >8h OR cause = illness/infection OR lifestyle-only management with very high BG

What happens physiologically during a high blood glucose episode? Sustained hyperglycemia triggers oxidative stress and inflammation in blood vessel walls. Glucose molecules attach to proteins in a process called glycation, temporarily impairing their function. High glucose also causes osmotic effects - drawing water from cells, increasing urination, and causing dehydration.

Recovery isn't just about glucose returning to range - your body needs time to clear inflammatory signals, rehydrate, and restore normal cellular function. Illness-related highs are particularly slow to resolve because the underlying immune response continues driving glucose up, even after you've corrected the initial spike.
