Why do I still feel stressed even though my blood sugar is well controlled?

This study confirms that emotional stress, anxiety, and poor sleep are common even among people with excellent blood sugar numbers. Living with a demanding chronic condition takes a real mental toll. Please speak with your care team about diabetes distress — it is a recognised condition and support is available.

Does better technology mean I won't need mental health support?

Not necessarily. While advanced insulin systems improve blood sugar control, this study found they did not reduce distress or improve sleep compared to other treatments. Mental health support remains important regardless of what technology you use.

What is diabetes distress and how common is it?

Diabetes distress is the emotional burden caused by the constant demands of managing diabetes — worrying about blood sugar, complications, and daily management tasks. This study found 55% of all participants experienced significant distress, even those with well-controlled blood sugar.

Advanced Insulin Pumps Don't Ease Mental Burden of T1D

Key takeaways

✓Second-generation AID systems helped 58% of users reach their HbA1c target of 7% or below — the highest rate of any treatment group
✓Users of the latest automated insulin systems reported greater satisfaction with their diabetes treatment
✓The study highlights an important unmet need, encouraging care teams to address mental health alongside blood sugar management

What This Study Found

Researchers studied 1,731 Canadian adults with type 1 diabetes to see whether the latest automated insulin delivery (AID) systems — often called "closed-loop" or "artificial pancreas" systems — improved not just blood sugar levels, but also emotional wellbeing and quality of life.

The Good News: Better Blood Sugar Control

People using second-generation AID systems (the most advanced available) were more likely to hit their HbA1c target of 7% or below:

58% of second-generation AID users reached their HbA1c goal
41% of first-generation AID users reached their goal
37% of those using CGM with daily injections reached their goal
32% of those using no CGM reached their goal

Users of the latest systems also reported being more satisfied with their treatment overall.

The Concerning Finding: Mental Burden Stays High

Despite better blood sugar numbers, the emotional and mental challenges of living with type 1 diabetes remained just as high across all treatment groups:

55% of all participants reported significant diabetes-related distress
63% reported poor sleep quality
Even among those who achieved their blood sugar target, 48% still had high distress and 60% still had poor sleep

There were no meaningful differences in fear of low blood sugar, confidence managing lows, worry about high blood sugar, distress, sleep, or overall wellbeing between the advanced technology group and everyone else.

What This Means for You

Technology is getting better at managing blood sugar — but it cannot fully address the emotional weight of living with a chronic condition. If you are using advanced diabetes technology and still feel stressed, anxious, or exhausted, you are not alone and this is not a personal failing. These feelings are common even among people with excellent blood sugar control.

Talk to your diabetes care team not just about your numbers, but about how you are feeling. Mental health support, diabetes distress counselling, and peer support groups can all make a real difference.

About the Study

This research analysed data from the Canadian BETTER type 1 diabetes registry. Most participants were female (69%), with an average age of 45 years and nearly 25 years of living with diabetes. Results were published in Diabetes, Obesity & Metabolism (2026).

Frequently asked questions

These are advanced 'closed-loop' insulin pump systems that automatically adjust your insulin based on continuous glucose monitor readings. They are sometimes called artificial pancreas systems and require less manual input than older pumps or injections.
