Can sleep apnea lead to chronic fatigue?

Yes, sleep apnea can indeed result in chronic fatigue. The disruption of sleep resulting from sleep apnea—either obstructive sleep apnea (OSA), central sleep apnea, or complex sleep apnea—can significantly affect the quality and quantity of sleep an individual gets, resulting in the sensation of constant tiredness and fatigue during the day.

This is the mechanism by which sleep apnea results in chronic fatigue:
1. Disrupted Sleep Cycles
Sleep apnea causes nighttime sleep to be disrupted often as the airway is narrowed or obstructed, leading to apneas (cessation of breath) or hypopneas (partial obstruction). These interruptions prevent the individual from entering restorative phases of sleep, such as REM sleep and deep sleep.

Without restorative sleep, body and mind aren’t able to recover, leaving them feeling drowsy and fatigued upon waking and throughout the day.
2. Insufficiency of Oxygen (Hypoxia)
During an apneic event, oxygen in the blood can plummet. The body responds by waking briefly to resume normal respiration. This oxygen desaturation with brief awakenings, repeated hundreds of times during the night, prevents the person from entering the stages of deep sleep recovery.
The consequence is chronic fatigue and daytime sleepiness. The body’s stress reaction to repeated oxygen deficiency can also elevate the levels of cortisol, a stress hormone that can further interfere with sleep and lead to fatigue.
3. Sleep Fragmentation
Sleep apnea causes awakenings to take place on a regular basis, but the individual may not always be aware of them. This sleep fragmentation lowers the quality of overall sleep and disrupts the regular sleep process, leading to inadequate sleep.
This broken-up sleep prevents the body from completing its own repair processes, including tissue repair, muscle growth, and memory consolidation, all of which contribute to the feeling of being rested and refreshed.
4. Increased Risk of Comorbid Conditions
Untreated sleep apnea individuals are at a high risk of acquiring other conditions that enhance tiredness, such as depression, anxiety, high blood pressure, cardiovascular disease, and diabetes. All these conditions, besides poor sleep, can enhance tiredness.
Sleep apnea may also lead to aggravation of insulin resistance and blood pressure, culminating in fatigue as the body tries to manage these chronic diseases.
5. Excessive Daytime Sleepiness
The most frequent consequence of chronic sleep deprivation as a result of sleep apnea is excessive daytime sleepiness (EDS). This can interfere with being awake and alert during the day, affecting job or school function, socialization, and overall quality of life.
Individuals with sleep apnea often complain of needing to nap during the day or finding it difficult to stay awake when driving, significantly affecting daily living.
6. Cognitive Impairment
Chronic fatigue associated with sleep apnea can also affect cognitive function, including memory, concentration, and judgment. Lack of restful sleep will result in mental fogginess, difficulty focusing, and a decrease in reaction time, all contributing to an overall state of fatigue and mental exhaustion.
Treatment for Chronic Fatigue Due to Sleep Apnea
The best news is that chronic fatigue caused by sleep apnea can usually be managed or alleviated with appropriate treatment. Common treatments for sleep apnea are:
Continuous Positive Airway Pressure (CPAP): A CPAP machine maintains open airways during nighttime, and thus the individual breathes normally while asleep as well as experiences deeper and more restorative sleep.
Lifestyle Changes: Weight loss, sleeping on the side (and not sleeping on the back), and avoiding alcoholic beverages or use of sedatives before bedtime will reduce the degree of sleep apnea symptoms.
Oral Devices: For cases of mild and moderate sleep apnea, there is a prescription that can be made by a dentist to prevent closure of the airway due to positioning the jaw.
Surgery: In some cases, surgery may be utilized to remove excess tissue or correct anatomical defects that lead to sleep apnea.
Conclusion:
Sleep apnea is a significant contributor to chronic fatigue due to its disruptive effect on the quality of sleep and the resulting daytime sleepiness and fatigue. It can cause cognitive impairment, mood disorders, and other medical complications if not treated. The better news is that with the right treatment, such as CPAP therapy, most individuals experience their quality of sleep, reduced fatigue, and overall well-being improve. If you experience persistent fatigue and suspect sleep apnea, it’s well worth seeing a healthcare provider for testing and potential treatment.
Sleep apnea, especially obstructive sleep apnea (OSA), has the potential to significantly influence weight gain via several mechanisms. The syndrome, which causes periodic changes in breathing during sleep, brings about metabolic changes, changes in appetite, and energy balance modifications that make weight maintenance and weight loss difficult. This is how sleep apnea influences weight gain:

1. Change in Appetite-Stimulating and Inhibitory Hormones
Sleep deprivation, a hallmark of sleep apnea with frequent awakenings and disrupted sleep, can disrupt the balance of key hormones that regulate hunger and satiety.
Leptin, a hormone that signals fullness, is typically lower when sleep is disrupted. Lower levels of leptin can stimulate appetite elevation and cravings, especially for calorie-rich foods.
Ghrelin, the hunger hormone, also increases with poor sleep. Elevated levels of ghrelin can cause calorie consumption, leading to overeating and weight gain.
These hormonal changes can create a cycle of viciousness with poor sleep causing increased hunger, increased calorie consumption, and finally weight gain.
2. Increased Insulin Resistance:
Sleep apnea has also been associated with insulin resistance, where the cells of the body become less responsive to insulin, a hormone that controls blood sugar. Insulin resistance can lead to higher levels of blood sugar, and later on, can result in the development of type 2 diabetes.
Higher levels of insulin also cause the body to store more fat, particularly around the stomach, making it harder for individuals to lose weight or be a healthy weight.
3. Fatigue and Reduced Physical Activity:
Daytime drowsiness is perhaps the most common symptom of sleep apnea. The ongoing fatigue can lead to less physical activity because people are too tired or do not have enough energy to engage in exercise or even in regular activities of daily living.
A sedentary lifestyle with broken sleep may cause weight gain and the inability to lose weight. Sedentary life has a strong association with weight gain and obesity as it reduces the total number of calories burned per day.
4. Altered Metabolism:
Sleep apnea also is linked with metabolic impairment, for example, with a decreased metabolism. This will cause the body to burn less calories when sleeping and lead to resistance to weight loss.
Disturbed sleep-induced stress may also raise cortisol production, a hormone that aids fat storage, especially around the midsection. Persistent elevated cortisol is connected with fat deposition and weight loss resistance.
5. Rest Disturbed Sleep
Sleep apnea disrupts the necessary sleep cycles, especially restorative and deep sleep like REM (Rapid Eye Movement) and slow-wave sleep. They are necessary for processes like repairing tissues, muscle-building, and burning fat.
Without restorative sleep, the body cannot improve, which may lead to poor metabolic efficiency and increased hunger due to low quality sleep.
6. Inflammation:
Sleep apnea provokes chronic low-grade inflammation in the body, partly caused by recurrent desaturation at night. Chronic inflammation is linked to obesity and retention of fat, particularly around the abdominal region.
This inflammatory response can negatively influence metabolism, hormone regulation, and the body’s ability to burn fat, making weight gain increasingly likely and weight loss increasingly hard.
7. Relationship Between Sleep Apnea and Obesity:
There is a twofold connection between obesity and sleep apnea. Excess weight, particularly in the context of fat stored around the waist, is one of the risk factors for sleep apnea. The fat deposition in the neck region tends to obstruct the airways and leads to sleep apnea.
On the other hand, sleep apnea can increase the difficulty in losing weight, and obesity and sleep apnea feed on each other in a vicious circle wherein obesity exacerbates sleep apnea and sleep apnea enhances obesity.
8. Increased Risk of Metabolic Syndrome:
People with sleep apnea are more likely to have metabolic syndrome, a cluster of conditions that add up to high blood pressure, increased blood sugar, more fat around the waist, and unhealthy cholesterol levels. Metabolic syndrome is strongly linked with weight gain, especially around the waist.
The synergy of these factors makes it more challenging for people with sleep apnea to manage their weight.
9. Medication Side Effects:
Some of the medications that are prescribed for the treatment of symptoms of sleep apnea, for example, antidepressants or anti-anxiety medication, produce side effects of weight gain. These medications also affect appetite and metabolism, thus leading to weight gain.
Conclusion:
Sleep apnea may cause weight gain by disrupting the hormone-regulating appetite, insulin resistance, which leads to fatigue and reduced physical activity, and enhancing metabolic dysfunction. The condition offers a vicious cycle where sleep disturbances make it harder to maintain a healthy weight, and overweight status can worsen sleep apnea. Proper control of sleep apnea by treatments such as CPAP therapy, weight reduction, lifestyle changes, and sleep hygiene can counteract its effect on weight and general health.
