Root Cause

Rapid-acting insulin (e.g., lispro, aspart) must be administered 15-20 minutes before a meal to match the glucose absorption curve; post-meal bolus misses the insulin peak, leading to dangerous postprandial spikes above 250 mg/dL.

中文

速效胰岛素（如赖脯胰岛素、门冬胰岛素）必须在餐前15-20分钟注射，以匹配葡萄糖吸收曲线；餐后推注错过胰岛素峰值，导致餐后血糖飙升至250 mg/dL以上，有危险。

Workarounds

  1. 85% success Instruct the patient to administer rapid-acting insulin 15-20 minutes before starting the meal. Use a timer or app reminder. For example: 'Set a 15-minute alarm after injecting, then begin eating.'

  2. 78% success If pre-meal timing is not possible (e.g., unpredictable eating schedule), use an insulin pump with extended bolus feature or ultra-rapid insulins (e.g., Fiasp) that can be taken at meal start with tighter window. Document in patient log: 'Bolus at meal start, not after.'

Dead Ends

Common approaches that don't work:

  1. 75% fail

    Post-meal bolus still misses the insulin peak; monitoring does not correct the pharmacokinetic mismatch

  2. 60% fail

    Splitting complicates dosing and still delays full insulin action; not standard therapy for most meals

  3. 70% fail

    Regular insulin has slower onset (30-60 min) and longer duration, increasing hypoglycemia risk if timed incorrectly
