Do hybrid closed-loop systems benefit T1D management?

Question

Hello doctor,

My 18-year-old son has type 1 diabetes and recently started using a hybrid closed-loop system. While his overall HbA1c has improved, he occasionally experiences unexplained blood sugar spikes after meals, even when we carefully count his carbohydrates. Could this indicate that his pump settings need adjustment, or should we consider other potential factors like stress or exercise? We also wonder if we should revisit his basal and bolus ratios as he continues to grow. Is there a general guideline for teenagers using advanced systems like this?

Please advise.

Hello,

Welcome to icliniq.com.

I am sorry to hear about your son's challenges.

Unexplained blood sugar spikes could indicate that his pump settings, especially basal and bolus ratios need adjustment. Teenagers often experience fluctuations in insulin needs due to growth, hormones, stress, or exercise. Regularly reviewing and adjusting his insulin settings is essential as his body changes.

Guidelines for teenagers:

Regular monitoring: Analyze CGM (continuous glucose monitor) data to optimize insulin settings.
Adjustments: Modify basal rates and carbohydrate-to-insulin ratios as needed.
Consider key factors: Account for stress, exercise, and hormonal changes.

Consulting with his healthcare team can help fine-tune his management plan. You are doing a great job supporting him through this!

Thank you.
