Sleep Problems Are Common in Type 1 Diabetes—Here's What Research Found

Sleep troubles are a common experience for people with Type 1 diabetes, but until now, researchers haven't fully understood why. A new study from the Canadian Journal of Diabetes examined sleep quality and sleep apnea risk in 210 adults with Type 1 diabetes, with an average age of about 46 years.

The findings were striking: nearly half of the participants (47%) reported poor sleep quality based on a standard clinical measure. Even more concerning, over one-third (37%) showed signs of elevated risk for obstructive sleep apnea, a condition where breathing repeatedly stops and starts during sleep.

The study looked for connections between sleep problems and various aspects of diabetes management and health. Researchers measured blood sugar patterns using continuous glucose monitors and assessed emotional factors like anxiety and stress.

One clear finding emerged: people who had developed microvascular complications—damage to small blood vessels often caused by long-term high blood sugar—reported poorer sleep quality. These same individuals also had a higher risk for sleep apnea. Cardiovascular disease was also associated with elevated OSA risk.

This suggests that the physical effects of diabetes complications may directly impact sleep, rather than sleep problems being purely a result of stress or anxiety about managing the disease.

One unexpected finding was that blood sugar patterns measured by continuous glucose monitors were not associated with sleep quality or sleep apnea risk. This means that how much someone's blood sugar varies day-to-day doesn't appear to directly predict sleep problems in this group.

While this might seem counterintuitive, it suggests that other factors—particularly the long-term complications of diabetes—may matter more for sleep health than short-term fluctuations in glucose levels.

Sleep is essential for overall health, and poor sleep is linked to worse diabetes management, weight gain, and other health problems. If you have Type 1 diabetes and experience sleep difficulties, this research underscores the importance of bringing it up with your healthcare team.

While this study identifies the problem, it doesn't provide treatment answers. That's a conversation for your doctor, who can evaluate your individual situation and recommend appropriate next steps. The key takeaway is that sleep problems are common in Type 1 diabetes and deserve attention, especially if you've developed diabetes-related complications.
