How Does Insomnia Impact Your Type 2 Diabetes Risk?

The new research led by the University of Bristol, supported by the universities of Manchester, Exeter, and Harvard, and funded by

Researchers used five sleep qualities — insomnia, sleep duration, daytime sleepiness, napping, and morning or evening preference (chronotype) to assess the impact on average blood sugar levels by measuring the HbA1c levels (

) in the blood.

Using Mendelian Randomization, researchers were allowed to remove any bias from the results by assigning people randomly according to a genetic code at birth.

The study, including 336,999 adults living in the UK, revealed that people who reported that they often had difficulty getting to sleep or staying asleep had higher blood sugar levels than people who said they never, rarely, or only sometimes had these difficulties. They also found out that there was no clear evidence for the effect of other sleep habits on blood sugar levels.

Alert for Night Owls!! Lack of Sleep (Insomnia) Can Increase Diabetes Risk

The findings gave an understanding that insufficient sleep can cause higher blood sugar levels and could play a direct role in the development of type 2 diabetes. Knowing this could open up new approaches to preventing diabetes (2^✔ ✔Trusted Source
The Impact of Poor Sleep on Type 2 Diabetes

James Liu, senior research associate in the Bristol Medical School (PHS) and MRC Integrative Epidemiology Unit (IEU) and corresponding author on the paper, said: “We estimated that an effective insomnia treatment could result in more glucose-lowering than an equivalent intervention, which reduces body weight by 14kg in a person of average height. This means around 27,300 UK adults, aged between 40- and 70-years-old, with frequent insomnia symptoms, would be free from having diabetes if their insomnia was treated.”

Currently, there are few treatments for insomnia such as cognitive-behavioral therapy (CBT), and short-term treatment of sleeping tablets or treatment with a hormone called melatonin if CBT does not work.

However, it is recommended that seven to nine hours of uninterrupted sound sleep every night reduces your risk of type 2 diabetes and maximizes your body’s full functioning (6^✔ ✔Trusted Source

Don’t forget that type 2 diabetes is a complex condition with multiple risk factors. Sleep is one of the first things to suffer when you’re suffering from Insomnia. If you’re not sleeping well, then managing blood sugar levels and staying on track with your diet can be a real challenge. If this sounds like you, you could be increasing your risk of type 2 diabetes. Besides good sleep, include a healthy diet and increase your physical activity for type 2 diabetes prevention.

Sleep and Sleep Disorder Statistics

Researchers hope future studies should assess the impact of the insomnia treatments on glucose levels in people with and without diabetes to establish potential new treatments for the prevention and treatment of diabetes.
