Can sleep apnea contribute to diabetes?

Yes, sleep apnea may lead to the development and progression of diabetes, particularly type 2 diabetes. The relationship between sleep apnea and diabetes is complex, and several mechanisms are responsible for how sleep apnea promotes diabetes risk or worsens existing diabetes.

How Sleep Apnea Leads to Diabetes:
Disturbance of Sleep and Insulin Resistance

Sleep apnea, and specifically obstructive sleep apnea (OSA), creates repeated pauses in breathing at night. These pauses, or apneas and hypopneas, cause fragmented sleep and decreased oxygenation (hypoxia).
The repeated periods of arousal and the fluctuating amounts of oxygen could lead to increased levels of stress hormones like cortisol and sympathetic nervous activation (which releases the “fight or flight” signal). These could set the stage for insulin resistance where the body cells fail to react appropriately to insulin.
Insulin resistance is a major risk factor for type 2 diabetes as the body needs more insulin to regulate blood sugar, and this can eventually lead to hyperglycemia.
Inflammation

Chronic low-grade inflammation secondary to intermittent hypoxia and frequent sleep disturbances is the hallmark of sleep apnea. This inflammation is responsible for causing damage to the body’s tissues, including those involved in insulin production and sensitivity.
Inflammatory markers are typically elevated in people with sleep apnea, which can contribute to the development of insulin resistance.
Impaired Glucose Metabolism

Studies have shown that people with untreated sleep apnea may have impaired glucose metabolism, or their body is unable to manage normal blood sugar levels after eating. This is typically seen in people with sleep apnea even before they develop diabetes.
The disturbed sleep rhythms and lower levels of oxygen in the body may interfere with the body’s function to metabolize glucose, eventually causing diabetes in the long term.
Obesity and Sleep Apnea

Obesity is a potent risk factor for both diabetes and sleep apnea. The overweight and obese are more at risk for sleep apnea, and the two diseases also come together.
Excess fat, particularly around the belly, is the cause of both sleep-disordered breathing and insulin resistance. When obesity is combined with sleep apnea, it forms a cycle that makes it more likely to develop diabetes.

Enhanced Susceptibility to Cardiovascular Complications

Sleep apnea also has a connection to heart disease, and sleep apnea and cardiovascular disease have several of the same risk factors as diabetes, such as high blood pressure and obesity.
Both sleep apnea and diabetes may be causative factors increasing the risk for developing heart disease and stroke and are thus most important to treat for overall good health.
Studies on the Correlation of Sleep Apnea with Diabetes:
Research has shown that patients with sleep apnea, particularly those with moderate to severe OSA, are more likely to develop type 2 diabetes. In some studies, people with untreated sleep apnea are 2-3 times more likely to have diabetes than people without sleep apnea.
Additionally, individuals with sleep apnea and diabetes will have more difficulty controlling their blood sugar, leading to unfavorable results of diabetes management.
Treatment of Both Conditions:
Treatment of sleep apnea can improve insulin sensitivity and control blood sugar levels. Positive airway pressure treatment (e.g., CPAP or BiPAP) is commonly prescribed for sleep apnea and can enhance glucose control in diabetic individuals.
Weight loss, also helpful to sleep apnea and diabetes, typically is part of the treatment regimen.
Self-monitoring of blood glucose and lifestyle factors like exercise and diet are important in the treatment of the two conditions.
Conclusion
Sleep apnea actually causes the development of type 2 diabetes and worsens the condition in people who already have diabetes. By causing insulin resistance, promoting inflammation, and disrupting glucose metabolism, sleep apnea is a significant risk factor for diabetes. Treatment of sleep apnea, for instance, with the use of CPAP therapy can improve insulin sensitivity and help manage diabetes overall.
Sleep apnea, and particularly obstructive sleep apnea (OSA), can critically affect cognitive performance. Sleep apnea is the repeated occurrence of sleep interruption with the breathing process being halted and suspended, resulting in oxygen deficiency and disturbed patterns of sleeping. The interruption could lead to varied cognitive impairments, affecting both short-term as well as long-term brain function.

This is how sleep apnea affects cognitive function:

1. Impaired Memory and Learning:
Short-Term Memory: Sleep apnea may also cause interference with working memory, namely the ability for holding and working on information in short time-spans. It can make one unable to engage in tasks like problem-solving, recalling directions, and memorization of new items.
Long-Term Memory: Chronic sleep apnea could have a detrimental effect on the consolidation of long-term memory. The brain processes and consolidates memory and learning acquired throughout the day while asleep, especially at deep stages of sleep (such as REM sleep). Sleep apnea’s interference with such sleep stages could undermine this process, resulting in challenges remembering and recalling things later on.
2. Decreased Attention and Concentration
People who have sleep apnea can exhibit poor concentration and short attention span. The cause is disturbed sleep, resulting in inadequate restoration of mental function so that people feel mentally fatigued and unfocused on tasks.
Deficits in attention manifest as difficulty following through on activities of a task, maintaining conversation, or following multi-step instructions, which are all so crucial for daily functioning.
3. Reduced Processing Speed
Sleep apnea is also associated with a slowing in cognitive processing speed. This would mean that sufferers will process information, respond to stimuli, or make choices more slowly. This slowing can be observed in the simplest of tasks (like response time) and more complicated things (like decision-making or critical thinking).
4. Executive Functioning Problems
Executive functions are complex thinking processes that help an individual to plan, organize, initiate, and complete tasks. They help with problem-solving, time management, and goal-oriented behavior.
Individuals with sleep apnea may have difficulty in carrying out these functions, e.g., planning tasks for the day, priority setting, and time management. This may have effects both in personal and working life.
5. Mood and Cognitive Decline:
Sleep apnea has also been associated with mood disorders like depression and anxiety, which further increase cognitive decline. Lack of sleep and low oxygen levels at night can adversely influence the brain’s emotional regulation function, creating a state of hyper-stress and mental exhaustion.
Long-term sleep loss due to apnea also impacts the brain’s systems of neurotransmitters, which are responsible for controlling mood and cognitive processes. This can lead to heightened irritability, poor concentration, and diminished stress management ability.
6. Higher Dementia Risk:
Chronic sleep apnea, especially if not treated, has been associated with the risk of neurodegenerative disorders, including Alzheimer’s disease and other dementias. Evidence shows that sleep-associated intermittent hypoxia (inadequate oxygen) may accelerate brain aging and contribute to the development of cognitive impairment and dementia.
Sleep apnea can lead to changes in the brain’s gray matter, which is responsible for processing information. This damage, over time, could predispose an individual to cognitive impairment and neurodegenerative diseases.
7. Disrupted Sleep Architecture:
Sleep apnea individuals experience frequent awakening throughout the night, disrupting the sleep cycle. This creates non-restorative sleep and reduced durations of restorative sleep stages, such as deep sleep and REM sleep, which are necessary for memory, regulation of emotions, and overall brain function.
Inability to experience continuous quality sleep does not provide an opportunity for the brain to fully rest and restore itself, leading to lowered brain function.
8. Brain Structure Effects:
Studies using brain imaging technology have shown that sleep apnea patients can exhibit structural changes in the brain, particularly those affecting memory, attention, and executive function. These changes can be attributed to chronic hypoxia and disrupted sleep.
For instance, white matter lesions (brain white matter injury, i.e., the area of the brain responsible for carrying signals from neuron to neuron) are more common in people with untreated sleep apnea. White matter injury can result in cognitive function impairment and is also linked to some diseases like vascular dementia.
9. Sleep Apnea and Risk of Stroke
Untreated sleep apnea has also been linked with a high risk of stroke, which in turn can lead to cognitive impairments such as memory loss, confusion, and difficulty with problem-solving. Sleep apnea and stroke can reinforce each other, with a compounded effect on cognitive abilities.
10. Reversibility with Treatment
The cognitive impact of sleep apnea is reversible or significantly improved through proper treatment. The most common treatment of obstructive sleep apnea (OSA) is the use of a CPAP (Continuous Positive Airway Pressure) machine, which maintains an open airway during sleep and regulates oxygen levels to normal.
Treatment has been shown to improve cognitive functions such as attention, memory, and executive functioning, especially in cases where sleep apnea was undiagnosed or untreated.
In some cases, the use of oral appliances or surgery may be recommended to correct sleep apnea and reduce its cognitive impact.
Conclusion:
Sleep apnea, particularly if left untreated, can significantly impact cognitive functioning by interfering with memory, attention, executive functions, and cognitive processing. Intermittent hypoxia and sleep fragmentation caused by sleep apnea may ultimately lead to neurodegenerative changes with an increased risk of developing dementia and other cognitive impairments. Fortunately, effective treatment measures such as CPAP therapy, along with medical therapy and lifestyle changes, can reverse cognitive impairment from sleep apnea, as well as restore sleep quality, in the majority of cases. Early diagnosis and control of sleep apnea are important for maintaining cognitive ability.
