Prediabetes is often considered a warning sign that type 2 diabetes may be on the horizon. While many people know that diet, exercise, and genetics can influence blood sugar levels, fewer realize that sleep health also plays an important role. In particular, research has found a strong connection between obstructive sleep apnea and prediabetes.
Understanding this relationship can help you take steps to protect both your overall health and your quality of sleep.
How Sleep Apnea Affects Blood Sugar
Obstructive sleep apnea (OSA) occurs when the muscles in the throat relax repeatedly during sleep, temporarily blocking the airway. These interruptions can happen dozens—or even hundreds—of times each night, reducing oxygen levels and disrupting restful sleep.
Over time, this cycle places stress on the body. Repeated drops in oxygen and frequent awakenings trigger the release of stress hormones, which can make it harder for your body to use insulin effectively. This condition, known as insulin resistance, is one of the defining characteristics of prediabetes.
As insulin resistance worsens, blood sugar levels can rise, increasing the risk of developing type 2 diabetes.
A Two-Way Relationship
The relationship between prediabetes and sleep apnea appears to work both ways.
People with prediabetes are more likely to have risk factors that contribute to sleep apnea, such as excess body weight. At the same time, untreated sleep apnea may make it more difficult to control blood sugar, creating a cycle in which each condition can worsen the other.
Although not everyone with prediabetes has sleep apnea—and vice versa—the overlap between the two conditions is significant enough that healthcare providers often recommend evaluating patients who show symptoms of both.
Warning Signs to Watch For
Sleep apnea often goes undiagnosed because it occurs while you’re asleep. Common symptoms include:
- Loud, chronic snoring.
- Gasping or choking during sleep.
- Morning headaches.
- Excessive daytime fatigue.
- Difficulty concentrating.
- Waking with a dry mouth or sore throat.
If you’ve been diagnosed with prediabetes and experience these symptoms, it’s worth discussing them with your healthcare provider.
Treating sleep apnea can improve sleep quality, increase daytime energy, and support overall health. For some individuals, addressing sleep apnea may also contribute to better blood sugar management when combined with healthy eating, regular physical activity, and medical care.
